For the Unilab power supply module, we have developed a special meter circuit in the
Elektor Labs with a four-line display that shows the output voltages and currents of a symmetrical configuration with two Unilab circuit boards.
Features
* Readings shown on a large backlit LCD module with 4 lines of 20 characters
* Voltage and current of each supply output (positive and negative) displayed
* Internal temperature of PS enclosure also displayed
* Selectable °C or °F temperature indication
* Signal conditioning circuitry specifically designed for a dual Unilab power supply
* Software-aided calibration procedure
* Powered by a separate transformer (2 ( 8 V / 3.3 VA)
