The Aim-TTi EX752M Multi-Mode Digital Bench Power Supply is a dual-output, 300W PSU capable of providing a maximum voltage output of 75V per channel or a maximum current output of 2A per channel.

As standard, the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply functions as a dual-channel power supply with two independent and isolated outputs. However, as it is equipped with Multi-Mode capability, the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply can also function as a single-output power supply capable of providing double the power.

Multi-Mode

When Multi-Mode is engaged, the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply can provide a single output at either 0 to 75V at 0 to 4A or 0 to 150V at 0 to 2A, making it ideal for high voltage applications. When functioning as a single-output PSU, the unused half of the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply will remain inoperative with blank displays.

Simple to Use

The Aim-TTi EX752M Multi-Mode Digital Bench Power Supply is equipped with simple-to-use analogue controls allowing the user to set voltage and current levels easily, efficiently and accurately. Each of the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply’s outputs is equipped with coarse and fine voltage controls and a logarithmic current control enabling low currents to be set precisely.

Constant Current and Constant Voltage Mode

Each of the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply's outputs can operate in Constant Voltage or Constant Current mode with automatic crossover and mode indication.

DC Output Switches

Furthermore, both of the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply’s outputs are equipped with independent DC On/Off switches. This allows the user to view the voltage and current setting prior to connecting the load and enables separate control of each output.

Three-Digit Meter

Additionally, each of the Aim-TTi EX752M Multi-Mode Digital Bench Power Supply’s outputs is equipped with a three-digit current and voltage meter with a large, bright display.

The Aim-TTi EX752M Multi-Mode Digital Bench Power Supply is a simple-to-use, dual-channel, high-voltage PSU with Multi-Mode capability enabling it to function as a single-output PSU.
