Encased in a durable IP68-rated aluminum shell, it offers comprehensive protections including overload, short-circuit, and over-temperature auto-recovery, making it ideal for automotive, solar, and industrial applications requiring reliable voltage transformation.

## 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 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: 20 Amp Output Rated Power: 480W 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 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 20A Step up ConverterQuestions: 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.

Review: Very cool product, with sparks and all! (36/48/v 60amp step down converter) - This is one of the most useful upgrades I've made to my boat. I boat-in remote camp for a week at a time. With long days on the water and not recharging every night, I sometimes end up with a dead starting battery due to livewells, stereo/amp, and other things running. This unit allowed me to rewire nearly all 12v accessories to my 36v trolling motor battery bank so that my starting battery always has power. And it pulls power from across all three batteries for even wear vs connecting accessories directly to individual batteries in the bank. One note: I read some reviews that state the unit was shorted upon arrival due to a significant spark created when attempting to connect the unit. I had the same experience. After emailing Cllena directly (thinking the unit was shorted), I was advised this is common and got some great help from them. I ended up putting a 50 amp switchable breaker in line between from the 36v bank and power input on the converter. Since the switch was off, I had no spark when connecting. I switched it on, and voila! It worked perfectly. So, don't assume a big spark is a sign of a short - it's just a result of 36v vs what some might be used to in 12v systems.
Review: Great for Bluetti! AC200 and AC200P - My Bluetti AC200 and AC200P 'solar generators' will charge at 100 watts from a 12v source OR 200 watts if from a 24v source. I had a LiFePo4 280ah 12v pack set up that has gobs of power but would take forever to charge the Bluetti at 100 watts. I figured if I could boost the voltage from the LiFePo4 pack to 24v, then I could supply the Bluetti with 200 watts of recharge when it needed it. The large LiFePo4 battery pack is charged by 1500w of solar so it had plenty available. In short, it worked like a charm! This device supplied 204 watts of 24vdc power to the Bluetti to keep is topped off while pulling 16.8 amps from the 12v battery. I used it like this for several months without a problem and can attest that it works great; just make sure your wiring from the battery to the 12-24v booster is of sufficient gauge. I recently upgraded the battery pack to 24v so I just bought the 24v-to-48v version of this product so I can charge the Bluetti at a full 700 watts at 48v from a 24v source. Since the unit is rated at 960w (20a), I do not expect any problems at all. I'll add the review on that product once I have it for a few months. Highly recommend!

### ⭐⭐⭐⭐⭐ Is 480W enough?
*by J***L on December 30, 2019*

Should you install a 12V solar system or a 24V solar system? If "bigger is better" why not 48V? So we wanted to install several 12V power points since we had a lot of luck with them previously. This device was the easiest way of enabling our 24V solar system to provide 12V. We also have a 12V water pump (although, I've recently discovered the same pump is available in a 24V version <sigh>) Connecting this converter to the "load" on our solar controller made it a simple matter to power the powerpoints and the water pump. The pump maxes out at 10Amps so 120W from this 480W converter should be no problem. OTOH, we have a 240V house (Aussie rules) but the 120V appliances are so much cheaper. We thought about connecting at 3000W inverter to this converter. Oops. I'm sure you see the problem.'' The converter works great. The problem is figuring out what you need it for, :-)
