Module nature: Synchronous rectification non-isolated step-down constant voltage and constant current module Input voltage: DC8-35V Output voltage: DC1.5-30V (clockwise increase, vice versa) Output current: 15A (MAX) (If the module exceeds 65 degrees, please strengthen the heat dissipation) Current limiting range: 0.25A-15A (clockwise increase, vice versa) Maximum power: 300W (MAX) Operating frequency: 150KHZ Conversion efficiency; up to about 96% (efficiency is related to the pressure difference and the use environment) Operating temperature; 0-85 degrees Celsius Output short-circuit protection: Yes (instantaneous protection) constant current (the current constant current value is set, and it cannot be short-circuited for a long time) Output anti-reverse flow: No (a diode can be connected in series at the output end to prevent reverse flow) Input reverse connection protection: Yes (MOS tube anti-reverse connection) Wiring method: terminal block Colour:Photo Color Material:plastic Package Contents: 1 x Anti -pressure module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
