💡 BEM Single Output Transformer 14840DA, 3 Phase, 32V/24V, Input: 480V Review

To control the electric water heater with NodeMCU, flashed with ESP Home. Works from 3.3V without problems. I hooked up the SSR to a large heatsink that was originally used for the AMD Athlon 64 and I believe it was rated for around 90W, which is probably a lot more than many heatsinks sold for these relays. It's been working for about a week now and I'm very happy with it. I'm on a variable speed power plan and can automatically turn the water heater off during the hours when the speed jumps…

I currently have a 40 amp version running which switches anti-sweat heaters in the fridge compartment (loading approx 20 amps at 115 volts). Depending on the ambient humidity detected by the controller, it may turn on, off, or fluctuate between the two states several times per minute throughout the day. So far it's done it with no issues, 24/7 365. Pretty impressed considering the price. This was a lot cheaper than replacing the entire controller after the original electromechanical relay…

Works well with my special 600 x 600 800W HEATED FIBERGLASS URETHANE BED! (Low wattage to avoid major warping, it just takes MUCH longer to get to 120, but it's worth the wait (with 3.175 GLASS ON TOP .090 6061-T6 ALUMINUM BIG 51MM METAL CLIPS) AND CUSTOM ABS ACCETONE SMOOTHED GRIPS : ). First, the FUSE blew every time I activated the HEATED BED. Thought it was SSR but after reading it found out someone else had the same problem - they used the AUTOSAVE and it solved their problem. I used a…
