Press Release for QPX600D dc power supply from Aim-TTi

Dual 600 watt power supply offers 80 volts and 50 amps

The new QPX600D from Aim-TTi is a dual output 1.2 kW power supply using the company’s latest PowerFlex+ regulation to provide up to 80 volts or up to 50 amps on each 600 watt output.

A conventional PSU has a fixed current limit giving a power capability that reduces directly with the output voltage. The PowerFlex+ design of the QPX600D enables higher currents to be generated at lower voltages within an overall power limit envelope.

Each output can provide more than six times the current of a conventional PSU of the same maximum voltage and power. Example voltage/current combinations include 80V/7.5A, 60V/10A, 40V/15A, 28V/20A, 18V/30A and 10V/50A.

The QPX600D can be operated as two entirely independent and isolated power supplies, each with its own comprehensive graphic LCD display. Alternatively multiple isolated tracking modes are available including ones intended for series and parallel operation which provide metering of total voltage or total current respectively. This enables up to 160 volts or 100 amps to be provided when required.

The two outputs can be switched on or off either independently or synchronously. Synchronous switching of the outputs is of increasing importance for circuitry which can lock-up or even be damaged if one voltage rail is present without the other.

The front panel control system allows settings to be made using direct numeric entry, or via a spin wheel. Setting resolution is 1mV or 10mA and a number of non-volatile settings stores are provided.

Two versions of the product are available. One with analogue remote control only, and another with analogue and digital interfaces including USB, RS232, GPIB and LAN (Ethernet). The LAN interfaces is compliant with LXI class C (LAN eXtensions for Instrumentation).

The QPX600D is suitable for bench top or rack mounted applications. It has built-in tilt feet and a 3U high rack mount kit is available.
