Triple-output programmable power supplies optimized for automated test apps

November 6, 2019 By Lee Teschler Leave a Comment

The ABI Programmable Power Supply (PPS) is a triple-output programmable power supply with each channel independently adjustable. Each output can provide 40 W of power (1 A @ 40 V rising to 8 A @ 5 V under all ac supply conditions) with a resolution of 1 mV and 1 mA. All PPS channels are isolated and have equal capabilities. The output polarity can even be reversed under software control, removing the need to swap cables to supply negative voltages.

In combined operation, the channels can be placed into arbitrary system-8groups for easy multichannel control. Any number of channels can be added to a group, and up to three independent groups can be created. Grouped channels remain isolated but work to achieve a common goal, these include:

Isolated Voltage Tracking – channels are set equal to the group’s voltage limit but have independent current control. This can be used to generate tracking bipolar voltages or tracking unipolar voltages relative to different grounds.*
Power Sequencing – channels respond to a group On/Off control.
Voltage Stacking – When voltages above 40 V are required, channels can be externally wired in series. The group’s set voltage will be divided equally between all members of the group to make efficient use of each channel’s power envelope and the group’s current limit will be applied to all members equally.
Parallel – When currents above 8 A are required, channels can be externally wired in parallel. The group’s set current limit will be divided equally between all members of the group to make efficient use of each channel’s power envelope and the group’s voltage limit will be applied to all members equally.

The ABI PPS is a new module in the System 8 series of automated test modules, but the PPS can also be used as a versatile standalone PC-controlled power supply. The System 8 range of modules are designed for PCB repair and end-of-line testing, controlled by simple-to-use but versatile Ultimate software. The PPS features remote sense and low ripple/noise, suits a wide variety of test and measurement scenarios, and can be preprogrammed with ABI’s Ultimate sequencing software.

From low to medium volume production test, through to predictive/corrective and PCB troubleshooting tasks, the PPS can be programmed for criteria such as: voltage, current, and power comparison Pass/Fail testing or power sequencing soak tests, with preset targets; comparisons and traceability are also available. The convenient front panel RGB LEDs indicate each output state, including fault conditions and channel identification. Customizable, programmable, and automatic voltage and current protections are available.

Made in Europe by ABI Electronics Ltd., a leading embedded test equipment manufacturer, the ABI PPS is available now from ABI’s technical distributor Saelig Company, Inc., Fairport, NY.

Current Digital Issue

A frequency you can count on There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that…
