With a basic accuracy of ±0.04% across a frequency range from DC to 600 kHz, and benchmark accuracy of ±0.03% rdg. ±0.01% f.s. at DC and 50\/60 Hz, it provides the precision required for applications such as WLTP (Worldwide Harmonized Light Vehicles Test Procedure) testing, DC-DC converter efficiency evaluation, and other demanding measurement tasks in R\u0026amp;D, production, and field environments.\u003c\/p\u003e\n\u003cp\u003eThe power analyzer supports direct voltage input up to 1500 V DC (CAT II) and 1000 V DC (CAT III), enabling measurements in high-voltage environments such as photovoltaic inverters and other modern power conversion systems. Furthermore, its CAN input function allows the PW4001 to obtain battery voltage values via CAN communication, so that power can be calculated without direct voltage probing. This is particularly important in environments where safety considerations make direct access to terminals difficult, for example when testing fully assembled electric vehicles.\u003c\/p\u003e\n\u003cp\u003eThe combination of a fixed four-channel design, high accuracy, and wide frequency bandwidth makes the PW4001 ideally suited for efficiency testing of single-stage converters. Typical applications include energy storage system (ESS) converters and the inverter stages used in heat pumps, compressor drives, and basic industrial motor drives, where DC input and AC output can be measured simultaneously.\u003c\/p\u003e\n\u003ch3\u003eSensor Communication and Phase Correction\u003c\/h3\u003e\n\u003cp\u003eFor current measurement, HIOKI provides a wide range of dedicated sensors, from compact clamps for low currents to high-bandwidth probes capable of several kiloamps. As both the analyzer and the sensors come from a single source, they communicate directly, automatically exchanging calibration and correction data. The HIOKI PW4001 Power Analyzer applies phase shift corrections with 0.001° resolution, minimizing error and ensuring that each sensor performs to its full potential. HIOKI’s high-precision current clamps are particularly valued for their ability to capture currents quickly and safely on complete systems without the need for direct wiring.\u003c\/p\u003e\n\u003ch3\u003eDC Operation and Long-Term Recording\u003c\/h3\u003e\n\u003cp\u003eWith the optional DC power input, the analyzer can operate directly from a DC supply such as a car or truck battery or a portable battery pack within a voltage range of 10.5 to 28 VDC. This makes it ideal for field tests where AC power is not available. Its 16 GB internal memory enables long-term recording without external USB devices, reducing the risk of interrupted measurements.\u003c\/p\u003e\n\u003cp\u003eDesigned for harsh conditions, the PW4001 operates from −20 °C to +50 °C and is specified for vibration resistance up to 4.6 G. It also meets the requirements of WLTP and SAE J1634 testing at −7 °C, ensuring stable performance in certified cold chamber evaluations as well as in real driving tests.\u003c\/p\u003e\n\u003ch3\u003eSystem Integration and Automation\u003c\/h3\u003e\n\u003cp\u003eThe PW4001 Power Analyzer is ideally suited for integration into test benches and automated test environments. With LAN interfaces supporting SCPI, Modbus\/TCP, and XCP-on-Ethernet, it can be controlled directly from existing systems. An integrated HTTP server allows browser-based operation without additional software, while FTP client and server functions make internal storage accessible like a remote file drive.\u003c\/p\u003e\n\u003cp\u003eFor extended monitoring, an optional 16-channel analog output function is also available, allowing waveforms and key parameters to be output in real time.\u003c\/p\u003e\n\u003ch3\u003eAdvanced Analysis and Test Functions of the PW4001 Power Analyzer\u003c\/h3\u003e\n\u003cp\u003eBeyond delivering numerical results, the PW4001 provides oscilloscope-like visibility. With four voltage and four current channels, engineers can view eight signals at once and capture them at high sampling rates. Zoom, trigger, and cursor functions make it possible to analyze switching events and transients in detail, while integrated memory supports long-term recording of measurement parameters.\u003c\/p\u003e\n\u003cp\u003eFor more advanced evaluation, the optional motor analysis package supports up to two motors, calculating motor power from torque and RPM while also providing vector displays and harmonic analysis up to the 500th order. Up to 20 custom formulas can be defined, allowing engineers to adapt the analyzer to specific test requirements.\u003c\/p\u003e\n\u003ch3\u003eAutomatic Mode Detection for ESS and Regeneration\u003c\/h3\u003e\n\u003cp\u003eIn applications such as energy storage systems (ESS) or drive systems with regenerative braking, the efficiency calculation depends on the operating mode. During charging or generator operation, the relationship between input and output power is reversed compared to discharging or motoring. The PW4001 automatically detects these modes and adjusts the efficiency calculation accordingly. This prevents incorrect results such as apparent efficiencies greater than 100% during regenerative operation.\u003c\/p\u003e\n\u003cp\u003eWhen larger systems must be evaluated, up to eight PW4001 units can be synchronized via BNC, enabling time-aligned measurement across 32 channels and supporting complete system-level analysis of PV or EV powertrains.\u003c\/p\u003e\n\u003cp\u003eFrom xEV energy consumption testing to converter, inverter, motor, and PV efficiency measurements, the PW4001 provides the versatility and reliability required for modern power analysis.\u003c\/p\u003e\n\u003ch3\u003eIEC Harmonic and Flicker Measurement with PW9006\u003c\/h3\u003e\n\u003cp\u003eThe optional PW9006 IEC Harmonic\/Flicker Function extends the PW4001 with IEC-compliant measurement according to IEC 61000-4-7 (harmonics and interharmonics) and IEC 61000-4-15 (voltage fluctuations and flicker).\u003c\/p\u003e\n\u003cp\u003eBy simply selecting the IEC measurement mode, the analyzer is automatically configured to perform standard-compliant measurements. Harmonic measurement supports up to the 200th order, while flicker evaluation includes the key parameters Pst, Plt, dc, dmax, and Tmax, making the PW4001 suitable for EMC testing, harmonic evaluation, and grid interconnection assessment.\u003c\/p\u003e\n\u003cp\u003eThe PW9006 function can be ordered together with the PW4001 or activated later using a license code.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cstyle\u003e\na {\n    text-decoration: none;\n    color: #464feb;\n}\ntr th, tr td {\n    border: 1px solid #e6e6e6;\n}\ntr th {\n    background-color: #f5f5f5;\n}\n\u003c\/style\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003ch3\u003eOverview of PW4001 Models\u003c\/h3\u003e\n\u003cdiv class=\"___1dmoc29 f10pi13n ftgm304 f1enuhaj fdclmfp f1nbblvp fat0sn4 f1ov4xf1 fekwl8i f1lmfglv f1oz7aqm f1abmfm4 f1w619qj f16h0jq8\"\u003e\n\u003ctable class=\"___1vyiefv f1ddd56o f16vktn6 f1ahpp82 f11qra4b f1uinfot fibjyge fvueend f9yszdx f1fu4s3n f3l3pb3 f10ghnd0 f8fmt76 fjvbh62 f1qrqxae f1vw5qpk fc02sbz fxawf59 fymf513 f1aoyrul f1el8yx3 f1pymoxg f1ofu761 fe6itr f7coize f1794535 f1o0pw0q fbjjl9v fk1v6el f16pyhcb f1ixlhx9 f12zef0i flu5r5u f19haqzy f1owmcxx f1oddm8q f1004tna fcoaxci fh0ee9u f15v23i2 f1dmj53 f1r1gcv9 f14z1veh ffufd3x f1ypplot f1660cg\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eD\/A Output\u003c\/th\u003e\n\u003cth\u003eMotor Analysis\u003c\/th\u003e\n\u003cth\u003eDC Power Supply\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePW4001-01\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePW4001-02\u003c\/td\u003e\n\u003ctd\u003e☒\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePW4001-03\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003ctd\u003e☒\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePW4001-04\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003ctd\u003e☐\u003c\/td\u003e\n\u003ctd\u003e☒\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePW4001-05\u003c\/td\u003e\n\u003ctd\u003e☒\u003c\/td\u003e\n\u003ctd\u003e☒\u003c\/td\u003e\n\u003ctd\u003e☒\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cp\u003e• PW4001 Power Analyzer\u003cbr\u003e• Startup Guide ×1\u003cbr\u003e• Power Cord ×1\u003cbr\u003e• USB Cable ×1\u003cbr\u003e• D-sub 25-pin Connector ×1 (PW4001-02, PW4001-05)\u003cbr\u003e• DC Power Connector ×1 (PW4001-04, PW4001-05)\u003c\/p\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003e• CT6834 (500 A) AC\/DC Current Clamp\u003cbr\u003e• CT6833 (200 A) AC\/DC Current Clamp\u003cbr\u003e• CT6831 (20 A) AC\/DC Current Clamp\u003cbr\u003e• CT6830 (2 A) AC\/DC Current Clamp\u003cbr\u003e• CT6841A (20 A) AC\/DC Current Clamp\u003cbr\u003e• CT6843A (200 A) AC\/DC Current Clamp\u003cbr\u003e• CT6844A (500 A) AC\/DC Current Clamp\u003cbr\u003e• CT6845A (500 A) AC\/DC Current Clamp\u003cbr\u003e• CT6846A (1000 A) AC\/DC Current Clamp\u003cbr\u003e• CT6877A (2000 A) AC\/DC Current Sensor\u003cbr\u003e• CT6876A (1000 A) AC\/DC Current Sensor\u003cbr\u003e• CT6875A (500 A) AC\/DC Current Sensor\u003cbr\u003e• CT6873 (200 A) AC\/DC Current Sensor\u003cbr\u003e• CT6872 (50 A) AC\/DC Current Sensor\u003cbr\u003e• CT6862-05 (50 A) AC\/DC Current Sensor\u003cbr\u003e• L1000 Voltage Cord\u003cbr\u003e• PW9006-01 Activation Code Card\u003cbr\u003e• VT1005 AC\/DC High Voltage Divider\u003cbr\u003e• SP7001-95 Non-Contact CAN Sensor\u003cbr\u003e• Z5302 Rackmount Fittings\u003cbr\u003e• C4001 Carrying Case\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Hioki","offers":[{"title":"Default Title","offer_id":58412357058892,"sku":"70064494","price":10488.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/2245\/6652\/files\/PW4001_02_4.jpg?v=1786730118","url":"https:\/\/www.testequity.co.uk\/products\/hioki-pw4001-03-70064494","provider":"TestEquity UK","version":"1.0","type":"link"}
