System 8 Programmable Power Supply (Pps)

The Programmable Power Supply (PPS) is ABI’s most ambitious power module developed for the SYSTEM 8 range. Over 35 years of excellence in product design and manufacturing were applied to the making of this USB driven, versatile unit that suits various test and measurement scenarios. From low to medium volume production test, through to predictive/corrective and PCB troubleshooting tasks.

All PPS channels are isolated and have equal capabilities. In normal operation, each channel is fully independent and isolated. This is equivalent to having separate single output power supplies. The output polarity can even be reversed in software, removing the need to swap cables over to provide negative voltages.

In group operation, channels can be placed into arbitrary groups for easy multichannel control. Any number of channels can be added to a group, and up to 3 independent groups can be setup and controlled. 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 40V are required, or higher currents (8A MAX) 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 channels power envelope and the group’s current limit will be applied to all members equally.

Parallel – When currents above 8A 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 channels power envelope and the group’s voltage limit will be applied to all members equally.
