Three Linear Triple Output Power Supplies launched by Global Specialties feature have fully programmable isolated outputs which can be adjusted independently or combined in series or parallel for higher voltage or current. Each model offers variable voltage and current on two channels, with the third channel output rated at 6V & 5A.

Each front panel has a bright 4.3-in. TFT LCD which displays all three outputs simultaneously and a USB connector for easy access to firmware updates. There are both convenient cursor keys and a rotary control knob for precise voltage and current settings.

Using the keypad, menu soft keys, output controls, and lock function, users can control their power needs.

The rear panel offers output terminals for remote sense. Connection to a PC is through either an RS-232 or USB connector using standard SCPI communication protocols.

In tracking mode, a user-defined ratio between two outputs is maintained and allows adjustments across the two channels from one control.

For example, use this with bipolar circuits, setting up positive and reverse connected negative supplies and maintaining their symmetry.

Each model offers timer-controlled output function, constant voltage (CV) and constant current (CC) modes, as well as memory to store and recall up to 40 instrument settings. The series features both overvoltage (OVP) and overcurrent (OCP) protections.

All models in the series feature excellent load and line regulation at 0.01% plus programming and readback resolutions of 1mV and 0.1mA.

Applications include Education, R&D design, or production testing.

Available immediately, Global Specialties’ Premium Series power supplies are all backed by a one-year warranty.
