QPX600D and QPX600DP - DC Power Supplies

QPX600D DC power supply
The QPX600D dc power supply offers dual isolated outputs of 600 watts each using PowerFlex+ regulation to provide a very wide range of voltage/current combinations. It is available in two versions, with and without digital control interfaces.

The two outputs can be connected in series or parallel externally. The unit provides voltage and current tracking, sync on/off and series and parallel metering modes to allow it to behave like a single channel 1200W unit.

High precision

With setting controlled by instrumentation quality 16 bit DACs, the QPX600D offers high accuracy and stability. Local setting can be done using either the numeric keypad or the spin-wheel, and setting resolution is 1mV up to 50V and 2mV up to 80 volts.

Balanced multi-phase converter system

A balanced multi-phase converter system minimizes ripple and improves dynamic performance. This provides unusually low noise for the power level, coupled with good transient response

Bench or rack mounting

The QPX600D is well suited to either bench or rack-mount applications. All terminals are on the rear panel. The chassis is 3U high and a 4U rack mount kit with ½U ventilation above and below is available as an option (RM460).

Automation Interfaces

The QPX600D has an analogue remote control interface only. The QPX60DP has analogue, RS-232, USB, LAN (Ethernet) and GPIB interfaces. The LAN interface conforms with LXI class C.

Models

The two models differ only in the provision of digital interfaces:
QPX600D - version with no digital interfaces (analogue only)
QPX600DP - analogue, USB, RS232, LAN and GPIB interfaces
QPX600DP rear panel

PowerFlex Regulation

QPX600 PowerFlex curve
Up to 80 volts and up to 50 amps maximum per channel within a 600W power envelope

The TTi 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 (see power curve).

PowerFlex+ uses a balanced multi-phase converter system to minimize ripple and improve dynamic performance. Example voltage/current combinations per channel include 80V/7.5A, 60V/10A, 40V/15A, 28V/20A, 18V/30A and 10V/50A.
