Single Output, Fan-less Convection Cooling
The 175 Watt EX355R combines high frequency switch-mode pre-regulation with linear post-regulation. This excellent line and load regulation is matched by low noise and good transient response.
Four-digit Meters
The EX355R incorporates separate voltage and current meters on each main output with a fixed 10mV resolution, which avoids reading misinterpretation.
Remote Sensing
The EX355R incorporates remote sense terminals that can easily switch to enable/disable.
Constant Voltage or Constant Current
The EX355R's output can operate in constant voltage or constant current mode with automatic crossover and mode indication. Course and fine voltage controls are provided. The current control is logarithmic, enabling low current levels to be set accurately.
Safety Binding-post Terminals
The EX355R is fitted with TTi-designed output terminals that accept a 4mm safety plug with rigid insulating sleeve. These terminals also accept fork connectors or bare wires, giving maximum connection flexibility.
