进口EL303R直流电源代理,英国tti EL303R的产品描述：

Precision with Simplicity

The new EL-R series has been developed from the top selling EL series. By adding four digit meters and switchable remote sensing, the  EL-R series offers much higher precision whilst retaining the simplicity of operation which many bench-top power supply users prefer. Eight models are offered including single, dual and triple outputs and covering a power range of 30 watts up to 130 watts.
