Price Match Guarantee & Advice

The Aim-TTi QPX600DP Digital Bench Power Supply is a dual-output, laboratory DC PSU suitable for benchtop, system and rack-mounted applications. It has a maximum power output of 600W per channel and a total power output of 1200W. The Aim-TTi QPX600DP Digital Bench Power Supply is designed to provide maximum flexibility and supports digital bus interfaces for remote control.

Dual Independent or Tracking Outputs

The Aim-TTi QPX600DP Digital Bench Power Supply’s outputs are independent. Each one has a maximum power output of 600W and can support voltage outputs up to 80V and current outputs up to 50A within this power envelope.

When the outputs are wired in series or parallel, the Aim-TTi QPX600DP Digital Bench Power Supply can output up to 160V or 100A within the total power envelope of 1200W.  The Aim-TTi QPX600DP Digital Bench Power Supply features a selection of isolated tracking modes, including one designed for use during series and parallel operation; this mode will provide metering of the total voltage or total current.

Independent or Simultaneous Output Control

Both of the Aim-TTi QPX600DP Digital Bench Power Supply’s outputs include an On/Off switch allowing them to be activated and deactivated individually. Additionally, the Aim-TTi QPX600DP Digital Bench Power Supply features Both On and Both Off buttons for engaging and disengaging the channels simultaneously. This is useful when working on circuits that may be damaged if only one voltage rail is present.

PowerFlex+ Design

The Aim-TTi QPX600DP Digital Bench Power Supply’s PowerFlex+ design equips it with maximum flexibility as it allows the user to choose from more voltage and current combinations. It also enables higher currents to be generated at lower voltages within the overall power limit envelope: each of the Aim-TTi QPX600DP Digital Bench Power Supply’s channels can provide six times the current of a conventional PSU.

Additionally, PowerFlex+ utilises a multi-phase converter system to minimise ripple and improve dynamic performance.

Numeric or Rotary Entry

Voltage and current levels for each of the Aim-TTi QPX600DP Digital Bench Power Supply’s channels can be programmed numerically using the keypad. Alternatively, the jog wheel can be used to set the voltage and current levels at selectable increments. The Aim-TTi QPX600DP Digital Bench Power Supply has a high setting resolution of 1mV.

Memory Setting Stores

Voltage and current settings can be saved to the Aim-TTi QPX600DP Digital Bench Power Supply’s non-volatile stores, enabling rapid recall. This is particularly useful for repetitive testing. Each of Aim-TTi QPX600DP Digital Bench Power Supply’s outputs is equipped with a separate memory store.

Graphic Display

Each of the Aim-TTi QPX600DP Digital Bench Power Supply’s outputs is equipped with its own high-resolution, graphic LCD which can be programmed to display numbers and text in a range of sizes. When in Standard Display mode, the voltage and current are displayed in large characters and are accompanied by text annotations such as ‘CV mode’ and ‘Output On’.

During setting alteration, the Aim-TTi QPX600DP Digital Bench Power Supply will display the existing and new settings, or the actual and limit values in parallel. Furthermore, when configuring the complex functions, the Aim-TTi QPX600DP Digital Bench Power Supply provides text prompts or complete selection menus.

OVP and OCP Trips

When over-voltage and over-current trips are triggered, the cause is indicated on the Aim-TTi QPX600DP Digital Bench Power Supply’s display. The Aim-TTi QPX600DP Digital Bench Power Supply’s OCP and OVP trips can be activated by other fault conditions such as temperature and remote sense mis-wiring.

When triggered the OVP and OCP trips will shut off the output and provide a different level of protection.

Power Calculation

In addition to indicating the voltage and current, the outputs' displays can be programmed to show the total power provided to the load (V x A). The Aim-TTi QPX600DP Digital Bench Power Supply will display power to a resolution of 0.1W.

Low Resistance Calculation

Alternatively, the outputs' displays can be programmed to indicate the equivalent resistance of the load (V/A).

The Aim-TTi QPX600DP Digital Bench Power Supply’s Low Resistance Calculation function enables low resistance measurements to be made at high currents by using the remote sense terminals as a four-terminal connection. This method provides reliable results for components that operate at ampere levels, such as magnets.  

Current Meter Averaging

The Current Meter Averaging function stabilises the Aim-TTi QPX600DP Digital Bench Power Supply’s display by showing the average reading calculated from the last four measurements. This works to reduce the speed and degree of variation and is particularly useful when measuring rapidly changing loads.

Ergonomic Design

Housed in a 350mm (13 ¾”) wide, 3U-high case, the Aim-TTi QPX600DP Digital Bench Power Supply is suitable for both benchtop and rack-mounted applications. An OPTIONAL rack mounting kit is available, please call for details.

In addition to this, the Aim-TTi QPX600DP Digital Bench Power Supply’s remote sense terminals, analogue, logic and bus interface connectors are located on the front and rear of the unit.

Analogue and Logic Interfaces

The Aim-TTi QPX600DP Digital Bench Power Supply’s outputs feature analogue interfaces for voltage control of both output voltage and output current (non-isolated, one for each output). Control voltages are digitised and scaling can be selected as 0 to 5V or 0 to 10V for zero to full scale.

Similarly, the Aim-TTi QPX600DP Digital Bench Power Supply’s monitor output for voltage and current can be selected as 0 to 5V or 0 to 10V.

The Aim-TTi QPX600DP Digital Bench Power Supply also features an opto-isolated logic control signal for control of output on/off. It can be programmed as true = output on or true = output off. Additionally, the opto-isolated open-collector logic output signal can be set as true or false for output enabled or disabled, current limit, power limit or any fault trip.

Comprehensive Bus Remote Control

The Aim-TTi QPX600DP Digital Bench Power Supply supports RS-232, USB, GPIB and LAN (Ethernet) with LXI enabling remote operation. All these digital bus interfaces are at ground potential and are opto-isolated from output terminals. They provide full control of voltage, current, output on/off and set-up; the digital bus interfaces also facilitate read-back of voltage, current and status.

IVI Driver

The Aim-TTi QPX600DP Digital Bench Power Supply includes an IVI driver for Windows which provides support for high-level applications such as LabView, LabWindows and HP/ Agilent VEE.

The Aim-TTi QPX600DP Digital Bench Power Supply is a flexible, comprehensive and easy-to-use DC PSU.
