Output Terminal On The Front Panel, Use More Friendly. Has Both Lock And Power Display Function (WATT)Voltage And Current Setting Selector Used Switch Instead Of Slide Switch, Improved The RelibilitySetting And Reading Are More Accuracy,The Resolution of Amp meter is 1mA,Volt meter is 10mV. Ripple & Noise (-) less than 10mVZero overshoot (c.v mode and mode),Protect sensitive device. High efficiency 87%.Intelligent protection: Output short circuit protection, Tracking Over Voltage Protection (OVP), Tracking Over Current Protection(OCP), Over Temperature Protection (OTP) SMT components: Reflow soldering process, higher relibilityModel:-1601Operation Voltage Range:198 - 264Vac/100-144VacOperation Frequency Range:45 - 65HZOutput Voltage Range:0 - 32VOutput Current Range:0 - 5AEfficiency (220Vac/full load): equal 87%Full Load Input Current (220Vac):less than equal 1.4ANo Load Input Current(220V):less than equal 80mAVolt Meter Accuracy:less than equal 0.1% + 2 digitAmp Meter Accuracy:less than equal 0.1% + 3 digitsConstant VoltageLoad Regulation (0-100%):less than equal 30mVLine Regulation(198-264Vac/100-144Vac):less than equal 5mVRipple & Noise (-):less than equal 10mVRipple & Noise (.s):less than equal 2mVSet Accuracy:less than equal 0.3% + 10mVTransient Response Time (50%-100% Rated Load):less than equal 1.0msConstant CurrentLoad Regulation (90%-10% Rated Voltage):less than equal 50mALine Regulation (198-264Vac/100-144Vac):less than equal 20mACurrent Ripple & Noise (-):less than equal 10mAp-pSet Accuracy:less than equal 0.2% + 5mAPlug Type:EU Plug,it applies to Indonesia, Germany, France, , Italy and so on.Voltage:AC220VColour:GrayMaterial:aluminum alloySize:120x50x180mmPackage Contents:1 * Power Supply1 * Power Cable1 * English manual
