Power, Precision, Simplicity

The new EX-R series has been extended by incorporating models from the best selling EX series. By adding four digit meters and switchable remote sensing, the  EX-R series offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer. Six models are offered including single, dual and triple outputs and covering a power range of 175 watts up to 420 watts.
