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 60V (at input 75 volts) maximum current 25A. Product Model: SZ-8025CCCV Module name: 600w buck constant voltage constant current adjustable power supply module Module nature: non-isolated buck module (BUCK) Input voltage:12-75V; Output voltage range: 2.5-60V (must meet the buck condition, IN input multiplied by 0.8); Output minimum voltage: 2.5V<br><br>Maximum output voltage: approximately equal to the input voltage * 0.8 (for example, the input is 40V, 40V * 0.8 = 32V maximum output voltage is 32V.) Output constant current: 1-25A (continuously adjustable,) Maximum output power: 600W (working environment must be well ventilated) Continuous maximum working power: 500W (ventilated environment) Continuous maximum working current: 25A (under ventilated environment) Heat dissipation mode: air-cooled heat dissipation Input undervoltage protection: No Input over-voltage protection: None (over-voltage prohibited) Operating temperature: -10~+65 degrees Operating frequency: 80KHz 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) Work indicator: Yes (output voltage blue LED) Wiring method: comes with no welding terminals Wiring: "IN" for input, "OUT" for output Colour:Photo Color Material:Metal + Plastic The appearance of different production batches may be different but will not affect the use<br><br>Package Contents: 1 x Voltage anti
