Review on π₯ Comidox 1PCS DC-DC High Voltage Boost Converter: ZVS Step-up Booster Module for Capacitor Charging β Adjustable Voltage Output, 8~32V to 45~390V Power Supply by Terrance Duncan
High DC voltage! Light up, but be careful!
Surprisingly small power supply! Charges capacitors to metal level, beware! After turning off the power, it takes some time for the capacitors to discharge, so be careful! I'm currently experimenting with this as an alternative high-voltage power supply for a tube amp! So far it has been very reliable. Did some load testing: installed a bunch of power resistors, cranked the voltage up and was able to source 35+ mA at 359V with a 20V DC supply for over 1/2 hour with no zero. Questions. The radiator was only warm. I'm guessing this is good for an amp rated at no more than 5W, but so far so good1
