DC Power Supply

There are many excellent DC power supplies available on the open market. However, they are usually large and heavy, so not suited for portable
applications. Most of these supplies use manual controls and cannot be remote controlled.

The PSM-101 fulfills the need for a small, lightweight, USB controllable laboratory power supply. The small size and weight, low profile, rounded corners and touch controls, allow it to fit easily in a laptop case or student backpack. The touch controls improve reliability by eliminating mechanical potentiometers and switches.

The PSM-101 can form the basis for low-cost automatic test equipment. Or, combined with a digital voltmeter and other Syscomp instruments such as the CGR-201 CircuitGear oscilloscope, it creates the core of a portable, low-cost analog and digital electronics laboratory.

Based on modern switching technology, the PSM-101 eliminates the bulky, heavy power transformer and heatsink traditionally required in a lab power supply. The result is a power supply that is pocket-sized with an overall weight of only 110 grams.

The optional USB interface enables the PSM-101 to be controlled from a host computer. The software is Open Source and runs under Windows, Mac or Linux operating systems.
