## 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: 8V-40V DC Output Voltage: DC13.8V 20A Output Rated Power: 276W 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 8V-40V to DC 13.8V 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 8V/40V to13.8V 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.

## Questions & Answers

**Q: What is the peak current output for the cllena dc 8v-40v to 13.8v 20a automatic buck boost? will it run up to 25 amps, non-continuous?**
A: The amps seem pretty weak on these, I installed them on my RV to convert 48v lithiums (58v actual input) and they struggle to drive the two 35 amp jacks, and I have 4 of these in parallel. Volts are low to, 58v in, 11.5-12.2 out max.

**Q: What is the amp draw on the line side of the inverter**
A: This is a 360 watt converter and the specs say that it is up to 95 percent efficient; so, 360 divided by a nominal 48 volts DC divided by .95 is 7.9 Amps DC.  Assuming a close to worst case scenario, using a low battery voltage of 42 volts DC and 92% efficiency; it could draw 9.3 amps.  For sizing a fuse, 9.3 times 1.25 is 11.6 Amps DC.  In summary, if you assume a 10 amp draw and use a 15 amp fuse on the line side of this converter, you should be safe using those numbers.

**Q: What is the parasitic (open circuit output) power draw of the 48->24V 60 amp model?**
A: I have four of these connected in parallel  and it doesn’t even register 1 watt parasitic draw between all of them. I cant measure anything less than a watt so I would imagine a single one of these would be in the very very low milliamperes parasitic draw

**Q: Can i use this converter to power a standard 110v wall outlet?**
A: This is a dc-dc converter. It can't take any AC input.
