The module adopts step rectification scheme with high efficiency, the highest efficiency is up to 95%. Continuously adjustable output voltage and current Input voltage up to 75 volts, output voltage up to 50V (at input 75 volts) maximum current 25A. Wiring: For high power, the wiring should be as thick as possible. Conversion efficiency: up to 95% (efficiency is related to input and output voltage, current and differential pressure); Short circuit protection: Yes (constant current protection); Input reverse connection protection: no; Output anti-refill: no (to charge the battery, the output connected to inductive loads, such as connecting the motor must be added anti-refill diode) Parameters: Module name: 600w constant voltage constant current adjustable power supply module Module nature: non-isolated module () Input voltage:12-75V Output voltage range: 2.5-50V (must meet the condition, IN input multiplied by 0.8) Output minimum voltage: 2.5V Output constant current: 1-25A (continuously adjustable) Maximum output power: 600W Continuous maximum working power: 500W Continuous maximum working current: 25A Heat dissipation mode: air-cooled heat dissipation Work indicator: Yes (output voltage blue LED) Wiring : comes with no welding terminals Wiring: "IN" for input, "OUT" for output Voltage conversion list: 12-75V to 5V 12-75V to 9V 14-75V to 12V 17-75V to 14.8V 19-75V to 16.8V 22-75V to 1 9V 24-75V to 21V 28-75V to 24V 35-75V to 30V 41-75V to 36V 48-75V to 42V 55-75V to 48V Precautions: 1. This module is a step-down board and cannot be used as a step-up board. 2. If it is used for charging batteries or batteries, please add a diode to the output to prevent backfeed. size: 100 x 61 x 31mm Material: PCB+metal+electronic components colour: Random Color Note: Random color, don't accept the specified color.
