Lambda UK needed a visual load to demonstrate their new Vega SmartPlus microprocessor controlled, four channel supply. Three channels each have an LED, a voltmeter and a fixed load. The fourth channel has an LED, a voltmeter, an ammeter and a variable load with switchable modes for resistive or constant current behaviour. The load will work up to 20V and 20A (even sinking this current down to 0.5V). It is electronically limited as a safety precaution to a continuous dissipation of 250W and will automatically reduce the load if the heatsink temperature rises too high in case the fan is blocked.
