I'm doing a retrofit on a router with a servo dynamics mts30m4-38 26lb/in 8.6A 3700 rpm 140v servo with a 24vdc 44lb/in d97-52721 brake on the z axis. I need to get a DC power supply for this brake and am wondering what would be sufficient amperage to release it- can I just put an ammeter in series with the brake and a 24v power supply to get a direct reading and then size the supply based on that or is there a better way?
