## Description

Wiring: INPUT+ to BAT+, GND to BAT-; OUTPUT+ to LOAD+, GND to LOAD- 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:  12V DC battery as input power to 24V DC appliances as output load.  Specifications:  Input Rated Voltage: 12V DC Input Voltage Range: 10V-16 DC Output voltage: 24V DC Output Current: 40 Amp Output Rated Power: 960W Efficiency: 97% (half load); 95% (full load)  Ripple: 200mVp Line Regulation: ±0.2%  Load Regulation: ±0.2%  Voltage Accuracy: ±1.5% Enclosures: IP68  Case Operating Temperature: -40~85°C Total Size: 265*127*63mm(L*W*H) Weight: 2170g Features:  1. 100% full power and stable current output, non-isolated module.  2. Industry grade DC 12V to DC 24V step up 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 12V-24V 40A Step up 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.

## Features

- Input voltage range: DC 10V-16V; Output voltage: DC 24V(non-adjustable); Output current: 40A (rated working current); Output power 960W.
- High conversion efficiency: The conversion efficiency may reach 95%; Its dynamic response speed is 5 percent 200US, please lower the power or enhance heat radiation when temperature over 40℃
- 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: Trucks, taxi radio, emu, car audio, LCD TV, advertising screen, LED lights, monitoring system, motors, electronic systems etc.

## Questions & Answers

**Q: What gauge wire is on the converter?**
A: the 24V to 12V 40A conversion has a VERY undersized gauge wire, 12ga.  all wiring charts show 8ga minimum for 40A.  12ga is for 25A.  The product has very thorough specs, but missing the important one, wire gauge.  I have suspect the 40A is a peak rating and continuous rating might be in the 20 to 25A range.  I bought this to convert the 24V battery bank to 12V common voltage.  I will need to identiy all the loads that will be put on it to determine if a 20-25A converter is adequate.

My battery BMS is rated for 250A yet they put 2ga wires on it rated for 120A.  How can these companies use sub-standard wiring and claim to past various certifications?

**Q: can input voltage a bit off from its range written here? I want to connect a battery 15~16.8V to obtain 12V output with high amp**
A: you need to use a different inverter 1 from 12 volt to 12volt than your input from15 to 16.8 will come out as a stable 12volt

**Q: Can I connect this ti a 48v 12amp Lithium battery and step down to 12v?**
A: It should work and provide 48A-H at 12V when supplied by a 12A-H 48V battery. You do not want to load the 12V beyond its 30A max output or the corresponding max output amps of the battery.

**Q: Can you connect cllena dc 24v step down to 12v 120a 1440w dc/dc voltage converter to a 4000watt inverter?**
A: I’d expect so. Not too sure on what you’d loose in efficiency.
