Module nature: synchronous rectification non-isolated buck module Input voltage: 10-90VDC Output voltage: 2-60VDC (applicable to applications where the input voltage is higher than the output voltage cannot be boosted) Output current: Max 6A (please use derating when high voltage is output, and the module temperature exceeds 65 degrees requires external cooling) Maximum power: 100W (maximum current 6A at low voltage output) Working frequency: 180KHZ Conversion efficiency: 97.5% (typical value) Input anti-reverse connection: Yes colour: silver Material: metal size: 70 x 38 x 31mm Package Contents: 4 x 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.
