500w spindle power supply
Description
Alternative to the 100v power supply using an AC dimmer and rectifier modules: https://www.aliexpress.us/item/2255800663018492.html https://www.aliexpress.us/item/3256804883905949.html Also need wires, AC plug, heat shrink, DC barrel jack/connectors, mounting screws. and a little soldering. remove both heatsink and potentiometer from the board so you can mount it. on. the case, they don't get hot for this purpose. Check the specs of your spindle for maximum voltage, adjust trimmer while monitoring output with voltmeter, I've only tested this using 110v mains. Please don't do this if you can't figure out how to wire those modules. AC line is dangerous! NOT my responsibility if you damage your equipment.
