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 Relibility. Setting And Reading Are More Accuracy,The Resolution of Amp meter is 1mA,Volt meter is 10mVRipple & Noise (-) less than 10mV. Zero overshoot (c.v mode and mode),Protect sensitive deviceHigh 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:-1602Operation Voltage Range:198 - 264Vac/100-144VacOperation Frequency Range:45 - 65HZOutput Voltage Range:0 - 60VOutput Current Range:0 - 3AEfficiency (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, Spain, Italy and so onVoltage:AC220VColour:GrayMaterial:aluminum alloySize:120x50x180mmPackage Contents:1 * DC Power Supply1 * Power Cable1 * English manualOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
