## Description

Wiring: OUTPUT+ to LOAD+, OUTPUT- to LOAD-; INPUT+ to BAT+, INPUT- to BAT- Reminder: Never reverse the polarity. Use the enough big cable to avoid the voltage drop. Never connect to solar panel or wind turbine. Never charge the battery. Keep good air convection.  Daygreen P/N: A7D1220 Efficiency: 95% Input Voltage: 40-90VDC Output Voltage: 12VDC Output Current: 20A No-load current: <0.1V Ripple: 200mVp Line Regulation: ±0.2% Load Regulation: ±0.2% Voltage Accuracy: ±1.5% Enclosures: IP68 Dimension: 100*113*35mm Net Weight: 0.7kg Case Operating Temperature: -40~85°C Certificates: CE Rohs Warranty: 3 years MTBF: 100,000 hours  Application: 48V/60V/72V DC battery of vehicles as input power to 12VDC appliances as output load. QuestionsHow to choose the correct current for loads? For example, if the max current of your load device is 10A, then choose 10A/0.7=14.28A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current.
