Description: With short-circuit protection, over-current protection, over-temperature protection, over-voltage protection. The module is waterproof, anti-shock, and moisture-proof and has stronger durability. Tiny in Size and light in weight, hence is convenient to carry out for usage. Small heating; high transfer efficiency of 96 percent max; the power draw is about 15mA when there is No load; adopts synchronous rectification technology. It can be widely used in bus, cmb, large trucks, motor, solar generate electricity, display screen of bus and taxi, car audio device. Specification: Material: Aluminum Size: 75x74x31mm Package Includes: 1x DC/DC Converter Note: 1.Please add fuse in the input; and positive and negative pole of voltage should not be connected reversely, or power module would burn. 2.To ensure the module outputs enough voltage and power, please make sure enough voltage and power of input power supply. 3.We suggest you to leave current margin for longer usage life; and if your output current reaches the Max, you must enhance cooling.
