Certified with CE/RoHS and built to last up to 100,000 hours, this converter is engineered for professional-grade performance in demanding environments.

## Description

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 use for charge. Keep good air convection.  * Never reverse the polarity.  * Use the enough big cable to avoid the voltage drop.  Specifications:  Input Voltage Range: 40V-90V DC Output Voltage: DC12V 20A Output Rated Power: 240W 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  Weight: 550g Features:  1. 100% full power and stable current output, non-isolated module.  2. Industry grade DC 40V-90 to DC 12V step down/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 40V/90V to12V 20A 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

## Questions & Answers

**Q: Can I put two of these in parallel to get 720 watts?**
A: Not a good idea to simply connect in parallel.  However, if you hook each one to a 1 ohm ceramic resistor each, then connect them together.  The issue is that each one will want to be at a slightly different voltage and they’ll fight each other.  You need to buffer that difference with a resistor on each of them.

**Q: Large spark when conncting 72v battery normal?**
A: Yes, it is normal to get a rather unnerving spark when connecting the converter to the battery.

**Q: What in the input amperage required?**
A: That would depend on the AMP draw of the output, and the voltage of the input.  You can probably find a good calculator by googling.

**Q: what is the exact output voltage and can it be adjusted?**
A: The exact voltage is 12,4V and don’t have no ajustement
