50V20A 1000W LCD display CNC step-down adjustable power supply module      Features:    1. LCD can display input/output voltage, output current/output power/output capacity/output time;    2. Numerical control adjustment, accurate and fast, step-down output, output voltage 0-50.00V can be adjusted freely, limit current can be adjusted freely from 0-20.00A;    3. The output port is poured and does not burn;    4. You can set the module to be turned on/off by default;    5. It has a variety of software protection mechanisms, and the protection threshold is adjustable. When the working parameters of the module exceed the protection threshold, the output is automatically turned off;    6. Using synchronous rectification technology, the conversion efficiency is high: the efficiency is more than 90%;    7. Enlarging the heat sink and installing a fan to enhance heat dissipation.         Specification:    Display: LCD display    Input voltage range: 6-55.00V    Input voltage resolution: 0.01V    Output voltage range: 0-50.00V    Output voltage resolution: 0.01V    Output current range: 0-20.00A    Output current resolution: 0.01A    Output power range: 0-1000W    Input voltage accuracy: ±(1%+5 characters)    Output voltage accuracy: ±(0.3%+5 characters)    Output current accuracy: ±(0.5%+5 digits)    Typical output ripple: 150mV peak-to-peak    Normal working temperature range: -10& 8451;~40& 8451;    Capacity measurement range: 0-999.9AH    Statistical error of capacity energy: ±2%    Statistical time range: 0-100 hours    Step-down working mode: differential pressure>0.05%+1V    Size: Panel 79X43X42mm    Motherboard 106x76x40mm       Packing included:    1 * CNC power module        Note:    1.
