Description Technical Info Reviews

The Aim-TTi EX355P Digital Bench Power Supply is a single-channel PSU with an RS-232 interface. It is capable of providing a voltage output between 0 to 35V at 0 to 5A and has a maximum power output of 175W.

Constant Current and Constant Voltage Mode

The Aim-TTi EX355P Digital Bench Power Supply’s output can operate in either Constant Voltage or Constant Current mode and features automatic crossover and mode indication.

DC Output Switch

The DC On/Off switch allows the user to view the Aim-TTi EX355P Digital Bench Power Supply's voltage and current levels before connecting a load.

Voltage and Current Meter

Voltage and current data can be viewed via the Aim-TTi EX355P Digital Bench Power Supply’s large, bright display. This single-output PSU features a 4-digit voltage meter (resolution: 100mV) and a 3-digit current meter (resolution: 10mA).

Simple to Use

Voltage and current levels are easily, efficiently, and accurately configured using analogue controls. The Aim-TTi EX355P Digital Bench Power Supply includes coarse and fine voltage controls, as well as a logarithmic current control for setting low currents precisely.

Power-Down Memory

The Aim-TTi EX355P Digital Bench Power Supply will save the voltage, current, and output status at power-down and will restore these settings upon power-up.

RS-232 Interface

The Aim-TTi EX355P Digital Bench Power Supply can be digitally controlled via an isolated RS-232 interface. Via a simple command set the user can set voltage and current levels and engage/ disengage the output remotely. The RS-232 interface also provides a readback of metering values and operating status.

The Aim-TTi EX355P Digital Bench Power Supply is a bench-top, single-channel PSU with an RS-232 interface enabling remote operation.
