🔌 DROK 24V Power Converter Module - 4A 100W Switching Power Supply Board with Variable Input, AC 85-265V, Indicator - Industrial Grade Switching Power Supply Review

Many of these were purchased for domestic home use (to power Class D stereo amps). They appear to be slightly better than regular imported quality. However, I don't have any long-term data on them yet, but they look above average.

So far so good. Run 2a at 24 VDC continuously without excessive heat for about 20 minutes. I will do an additional test one to two months after ordering a suitable case for the device and update my rating with an endurance test in a few hours.

120 VAC input, 24 VDC output. Nothing more to say. I use it to power a garage door receiver that needs more current than the opener can supply. Nice neat packaging, works. Good thing the 120V terminals are not DIRECTLY next to the 24V terminals.

To be used in conjunction with buck converter to go from 120VAC to 5VDC to display Raspberry Pi and an integrated screen to display ActionTiles for my security/weather/environmental control/smart devices. Works perfectly! Extremely stable output voltage, stays constant at 24V without dropping.

Good product. Compact device for disconnecting a dual power supply. It doesn't have fan cooling, but heat dissipation is above average. An adjustable version would be great, but works well with buck/boost converters. Can't complain about the price. Brilliant!

Absolutely no instructions. There are no markings on the circuit board to inform the user which side is AC and which side is DC. Looks nice. However, until the seller publishes important BASIC information, it remains unused on my desk. UPDATE: I found a diagram showing AC and DC connections on a foreign website. As suggested, AC should be connected to the green plastic block (next to the soldered fuse). I stress HOW SUSPECT - SEEMS obvious but I wasn't sure. Comparing the PSU with the…
