3000W 0-120V 0-25A Adjustable Charger 0-60V 0-50A Power Supply Battery Charger Items Description: Features AC input: 90-130V or180V-260V AC, 47 to 63Hz (when 110V input , the output current is half of 220V , ) It can be used for lithium battery charger, lead acid battery charger and DC power supply. DC output voltage: choose 0-120v 0-60v Size / weight: 37cm*9cm*13cm(l-w-h)/3.8KG LED indicator light logo: red and green, double color instructions, red charging green finished or standby Efficiency: 93% Use for : lifepo4/ li ion /lipo/lead acid /lithuium battery Charging Mode: CC, CV, Output current : 0-25A or 0-30A adjustable Characteristic 1:The charging mode has the function of anti-reverse connection of the battery, and the output relay is disconnected. Turning on the output without the battery will automatically turn off the output and disconnect the output relay. 2:The power supply mode can not reverse the battery, the output relay is in a long-term on state, and the output terminal can maintain a steady voltage and supply output without connecting the load. Battery maintenance power supply, battery general charger Detailed introduction of the function. The range of the voltmeter is extended to 120V, and the minimum resolution of the voltmeter and ammeter is 0.01. The switch is directly controlled by the encoder, and the power consumption is only 1.5W after shutdown. Support is full of automatic shutdown. Three-stage charging is supported (for lead-acid batteries). Charging ampere-hour statistics are supported. Automatic calibration with one button is supported, eliminating the tedious debugging process, and the accuracy is up to 1%. Super fine tuning mode is supported with a minimum step of 0.003V. Automatic controlled false load (halogen tungsten lamp), fast voltage regulation without waiting. The software is protected from overvoltage and overcurrent, and the output is turned off if the voltage and current are slightly high, which makes charging safer. With a better temperature control scheme, it can still work at full current in a 30-degree environment.
