Internal-Installed EMI filter condenser Input frequency: 47-63HZ Output voltage stability:+-0.5% Can be used for DIN installation (EN50022-35) All range voltage input (85-264VAC,120V-370VDC) Output voltage inching range (-5%~+10%,adjusting potentiometer V) Have the function of soft-start (to limit the peak current of start and the pressure of the voltage to the components) The current of the load can be roughly adjusted (means the maximum protective current of the load, adjusting potentiometer A) Have the short circuit and over-load protection. (Over-load protection: 105%-135%) Insulation and voltage endurance: >1.5KV Power supply output with the LED indicator Ripple: <100mVp-p Efficiency: >80% Remote control function. (the remote control switch can control having and not having the output voltage) UPS function (External-connected battery can be charged when the AC power is supplied, the power supply will act as UPS when the AC power is off and the battery was connected.) Over-heat protection function (The main control CMOS chip stops output when the temperature is beyond 135 degree and the output will renew automatically when the temperature drops to certain level.)
