Meanwhile one of the zone friend Manjeet suggest to me that If I use a switch between the Servo boards and the power supply after the capacitors then there will be an open secondary and I can have a delayed switching after the surge has stabilized, so I am going to have a DPST switch rated 20 amps in between the UHU servo power supply and the UHU boards. In future I will use a delay switch to switch on the PS for the UHU - hope it works! |
