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 10mV. Ripple & Noise (-) less than 10mV Zero 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 relibility Model:-1601 Operation Voltage Range:198 - 264Vac/100-144Vac Operation Frequency Range:45 - 65HZ Output Voltage Range:0 - 32V Output Current Range:0 - 5A Efficiency (220Vac/full load): equal 87% Full Load Input Current (220Vac):less than equal 1.4A No Load Input Current(220V):less than equal 80mA Volt Meter Accuracy:less than equal 0.1% + 2 digit Amp Meter Accuracy:less than equal 0.1% + 3 digits Constant Voltage Load Regulation (0-100%):less than equal 30mV Line Regulation(198-264Vac/100-144Vac):less than equal 5mV Ripple & Noise (-):less than equal 10mV Ripple & Noise (.s):less than equal 2mV Set Accuracy:less than equal 0.3% + 10mV Transient Response Time (50%-100% Rated Load):less than equal 1.0ms Constant Current Load Regulation (90%-10% Rated Voltage):less than equal 50mA Line Regulation (198-264Vac/100-144Vac):less than equal 20mA Current Ripple & Noise (-):less than equal 10mAp-p Set Accuracy:less than equal 0.2% + 5mA Plug Type:EU Plug,it applies to Indonesia, Germany, France, , Italy and so on.
