Aim-TTi Digital Bench Power Supply 400W, 1 Output 0 → 20V 0 → 20A

The EX-R series of compact mixed-mode regulated power supplies offers output power from 175 → 420W. The models have high resolution four digit meters and switchable remote sense terminals.

Mixed-mode regulated with linear final regulation
Constant voltage or constant current with automatic cross-over
4 digit meters with 10mV and 1mA resolution
Switchable remote sense terminals for perfect regulation at the load
DC output switch enables voltage/current setup without load connected
Safety terminals accept fixed shroud 4mm plugs plus forks and wires
Silent fan-free convection cooling all models except EX2020R & EX4210R (intelligent fan cooling)

Opto-isolated RS-232 interface
Front panel controls can be locked out

The EX355P is a digitally controlled version of the EX355 with an isolated RS-232 interface. It offers a low cost solution for a basic programmable PSU, and will be sufficient for many applications where the sophistication and complexity of GPIB are not needed. A simple command set allows remote control of voltage, current and output along with read-back of metering values and operational status. Local control is via three rotary encoders providing rapid and accurate setting of voltage and current.

Separate voltage and current meters for each output
Safety output terminals

Switchable remote sense terminals for perfect regulation at the load
EX354RT has auxiliary output of 1.5V to 5V at 5A
