Cllena DC 36V 48V Step Down to 12V 30A 360W Voltage Reducer Converter, Waterproof DC/DC Buck Transformer Power Supply
Brand: Cllena
Categories: Electronics, Power Accessories, Power Converters

Wiring: OUTPUT+ to LOAD+, OUTPUT- to LOAD-; INPUT+ to BAT+, INPUT- to BAT- Note: * Never connect to solar panel, PWM/MPPT charge controller, inverter or wind turbine. * Never charge the battery. Keep good air convection. * Never reverse the polarity. * Use the enough big cable to avoid the voltage drop. Application: 36V/48V DC battery as input power to 12V DC appliances as output load. Specifications: Input Rated Voltage: 48V DC Input Voltage Range: 30-56V DC Output voltage: DC12V 30A Output Rated Power: 360W Efficiency: 97% (half load); 95% (full load) No-load current: <0.1V Ripple: 200mVp Line Regulation: ±0.2% Load Regulation: ±0.2% Voltage Accuracy: ±1.5% Enclosures: IP68 Case Operating Temperature: -40~85°C Weight: 550g Features: 1. 100% full power and stable current output, non-isolated module. 2. Industry grade DC48V to DC 12V step-down converter, efficiency up to 95%. 3. Die-cast aluminum shell, epoxy potting, cooling by free air convection; Waterproof level IP68 and anti-shock protection. 4. Protections: Over-current, Over-voltage, Over-temperature, Over-load and Short-circuit, auto-recovery when device is back to normal operating. 5. Certificates: CE/RoHS, 1 year warranty, lifetime up to 100,000 hours. Package included: 1 x DC 48-12V 30A Voltage Converter Questions: How to choose the correct current for loads? For example, if the max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current.

Input voltage range: DC 30-56V; Output voltage: DC 12V(non-adjustable); Output current: 30A; Output power 360W.
High conversion efficiency: Synchronization rectification technology-multiple intelligent protection function with high conversion efficiency and stability. The conversion efficiency may reach 95%.
Protections: Over-load, Over-current, Over-temperature, Short-circuit, Over-voltage.
Aluminum shell and silicone sealed design: Waterproof, Anti-shock, Anti-humidity and Dust-proof, more durable.
Wide application: Large trucks, taxi radio, emu, car audio, LCD TV, advertising screen, LED strip lights, monitoring system, motor, electronic systems and DIY etc.
