Aideepen 1200W 20A DC Converter Boost Car Step-up Power Supply Module Adjustable Voltage Converter 8-60V to 12-83V

Used for a DC heater works great on 24 volts and functionality is awesome 👍 power output is nice versus input! Works off my solar for free heating! I get a 1000 Watts from my converted heater in picture! Was AC now DC cool beans!

So far so good

Be aware that max output power is based on the voltage input. This is noted in the product description. Fuses on boost step up supply are 15A fuses. I'm using it to boost 12.5v to 48V for POE injection for a network. Has a low battery cut off, which is nice for battery fed applications. Min voltage is 10Vdc, which is still OK for 12.5 batteries. Found more detailed directions for set up on line...vendor should provide that with the product. It arrived with zero instructions.

I'm not all too suprised. It is a notoriously bad converter that is hated by all that use them. I'm in a bind and needed something fast so I had no choice. I needed to discharge my 14S 80AH NMC battery pack for a small EV type project. This test provided me both a way to do that and to stress test this device to see if it will work in my final application. The voltage was set to the highest it allows, 135V or thereabouts. The MOSFET is rated to tolerate 150V not leaving a great deal of design margin. But I had it this way so that way my 130V 300W lamps offer substantive load. The load of 3 130W lamps and 1 150W lamp is around 1.05KW, which is heavy but still under the maximum power rating. The current at the input was 30A, which is comfortably below the 40A input current rating (56% of maximum primary input current squared) The blown short failed MOSFET is CRSQ052N15N3 which is rated for 150V, 160A Id at Tj=25°C and 119A at Tj=100°C, and 4.8mΩ Rds(on). The most likely culprit is the poor thermal transfer to heatsink and no thermal protection on the silicon die. The device features a thermocouple and thermostatically controlled fan, which is a nice (and mandatory at the upper power levels). The chipset is the classic TL494. Very cheap IC, but it dates from the late 70s and is a voltage mode controller, so as a result this converter does not have current-mode control and no cycle-by-cycle current limit. Current limitation is implemented by having a second current control govern the duty cycle of the voltage mode controller, overriding the voltage control loop, and this current control loop suffers from low bandwidth concequentially MOSFET current can greatly exceed safe operating area. These controllers need to be redesigned using a more modern and capable chipset.

Works perfect for my need, boosting voltage from 12.3 to 14.5 and holds it right on the number when loaded. I'm not loading but about 8 amps that's only at start up after that to 2.5 continuous.

holy crap its still working special note on this. Do not have under a full load while turning input on (input current can spike to 100 amps and the main mosfet blows out) Avoid setting low voltage protection below 11.2 volts (see line above) Just because the low voltage protection light is on does not mean it is not working at all but just at a lower rate (less heat) Be sure to use both input connections for + and - at a high current output like 10 amp or more (one can result in input post melt down) At max current output keep an eye on your input wires and make sure they dont melt down from 40+ amps of current (yes 40+) If you want to keep this working at a max constant current replace the heat sink with something 2x the boards size a 200mm x80mm x40mm would do the trick and use a fan youll need it. I bought 2 of these from ebay and had a problem from day 1 with them and had to replace the main mosfet 3 times in both of them after the 3rd time they blew for no good reason i scrapped them and bought this one but those 2 did teach me a lot on some dont do's. I use this on low sun days for solar energy charging my Lithium battery packs low sun days do not produce enough voltage to get the packs charged so gotta use something and this works just fine as long as they are kept cool (below 70C) and not under a load when i turn on the input and have the low voltage setting no less than 11.2 volts. The Default heat sink is most certainly not enough the main mosfet and the other mosfets produce to much heat at a constant high current (around 22amps) and conducts the heat to the board heating every single component that is on the board so try to keep it under 70C to avoid any hiccups and small component fails. Thats be best advise i can give for these. Update 11-11-18 BLOWN yep not working anymore these things are totally NOT RELIABLE im so fed up with having to repair these things I put a shottky diode on the output to prevent it from getting reverse current from being hooked up to a battery to charge them so far its been stable but at a loss of 3 amps charging current reducing it to 17 amp max constant.

Just be sure to power up the unit FIRST, then turn on the load. I'm using one to get the 19 volts I needed to power a Beelink SER6 mini PC I use with portable ham radio. It's been perfect. This unit is overkill, for sure. But for the price, who cares? 😊

Ok, this works a dream! Bumped a 16.8v to 24v and been running perfectly since I got it. Output power is stable and the unit doesn't get too hot. Came with an automatic thermal fan that hasn't had to turn on yet. Running a 24v 1000w inverter off of it and having NO issues! Small for factor, mounting holes, heat sink. Easy to install and wire up. Great design. Priced better than most!

I received the 1200 w voltage boost converter, from the Aideepen store, through the Amazon Vine review program. I love playing with electronics, and I have plenty of step down voltage converters, but not any step-up converters. I have a variable voltage power supply / battery charger, but its output is dependent on the input voltage. With this voltage-up converter, I was able to upconvert a 42 Volt DC source to 80 volts DC, and send it in to my power supply / charger. I was then able to send out 70 volts on the power supply / charger. This dc to dc step up voltage converter is a fantastic addition to my electronic tools. It gives me a lot more versatility as to what voltages I can now pick and choose from.

The 1800 W is seriously aspirational. You might get that INPUT for a very short while, at a very specific combination of high input and output voltages. In practice, I'm getting a sustained 50 volts at 6.5 amps (325 watts) from 13.5 volts 28 amps input (86% efficiency). It needs fan cooling to sustain this. It overheats at 8 amps out (13.2 V 37 A input), and collapses entirely above that. But moderate your expectations and it works fine. It does all the things it's supposed to (CC, CV, overtemp protect).

This is a high power DC to DC buck boost convert with constant current and constant voltage setttings that work properly. Nicely constructed and electrically and mechanically robust. I did not test it to its limits (voltage and current) but for my application it worked fine at roughly 1/2 its rated power.

Using this with a 12.5V 175 watt Xbox power supply to charge a 20AH 12.8V lifepo4 battery. I set it to charge at 14.4V 10A and have done two full charges so far while watching an ammeter get to 0 before turning off. I'm also planning on using this in my vehicle instead of using the Xbox power supply(my vehicle doesn't always put out 14.5V). I followed instructions and advice of other reviews to set the current to zero and adjusting up after you start charging. As others mentioned it does get hot so a fan is probably necessary. Unsure of the longevity but hope it keeps kicking, it will mainly be used with/in a diy battery box for camping.

I mistakenly thought this was DC-AC when ordering it, that's on me, but despite not being able to use it for my needs I did test it out with a 15A 115VDC motor I had in storage and it seemed to hold up really well. I used my bikes 48V (54.7v) battery as a power source to test it, I set the output to 115V and hooked up the motor with a switch, everything worked well, I ran the motor until my battery reached 41V (under load), the entire time the converter ran smoothly, it got hot but not alarmingly so, the cooling fan did it's job well. I'll save this perhaps for a future project as it handled my testing so well, I feel comfortable recommending it
