Power Adjustable LED Display Switching DC Power Supply 220V 0-60V/0-20A For Laboratory and Teaching Summary: KPS series is a single set of output, high precision double display switch dc power supply. Machines have complete operating protection function, with high performance,  low ripple, high stability, light weight and small volume etc.. Current limiting protection can make KPS power supply and load against accidental damage.  KPS series power supply with low temperature control circuit, a cooling fan noise is low. Special point: 1, have complete operating protection function 2, highly efficient, low ripple, small volume, light weight 3, double display voltage, current, and high precision 4, voltage stabilization, current limiting, simple operation 5, dual voltage input and convenient choice 6, temperature control fan heat dissipation, low noise 7, Double potentiometer more precise adjustment Product application: 1, production line test 2, electrical maintenance 3, life products aging test 4, battery charging 5, laboratory, research and teaching 6, all other needs DC power supply Technical indicators: Input voltage:AC 220V±10%,50Hz Output voltage:0 ~ Nominal value Output current:0 ~ Nominal value Voltage resolution:0.1V Current resolution:0.1A Power effect:CV≤0.3%+10mV Effect of load:CV≤0.5%+30mV Ripple and noise:Vp-p≤0.5%+10mV Voltage display precision:±1%+1digits Current display precision:±1%+1digits Net/gross Weight (KG):5.0-5.3/6.2-6.
