Review on π‘ Pack of 5 JIUWU LM317 Buck Step Down Power Supply Modules for DIY-DC Linear Conversion by Jayme Newitt
When I use 1 relay and an LED everything was fine, but multiple relays work and the LED draws a maximum of 430mA.
Transition from 24V to 12V. When I use 1 relay and LED everything was fine, but when multiple relays and LEDs were driven max 430mA I had problems. After about 3 minutes it starts making a lot of noise, buzzing and hissing. I thought mine was bad so I changed it and the second one did the same. It's rated at 1.5A and I didn't even get close to that, also when I adjusted the voltage from a 24V source to 12V and then changed the source to 18V the output dropped to 10.3 V. I can try a heatsink but now I'm ordering another buck converter with a higher rated amp.
- Annual trial period
