Review on KNACRO Voltage Regulator Three Terminal Rectifier by Joshua Donnis
+/- 12V regulator for small DIY projects
Worked as expected using DC +/- input. I gave it 4 stars because the input filter capacitors are only 220uF which can result in excessive output ripple. If you're using the power supply for a small load (like a pair of op amps) you'll probably be fine. There is not enough space on the board for large capacitors, but they can be installed outside. Also, the heatsinks are very small, so pay attention to the power dissipation of the regulators. Note. I tested each branch independently with a 15 ohm load (800 mA at 12 VDC). The DC input voltage was +/- 20 volts. The AC test voltage was 40 VAC CTs (20 VAC per branch). During testing
- Alright!
- Expensive
