    48v power supply makes 65v

    I Wired up my powersupply (48v 7.3) and when the switch is on 115 it puts out 65v whitch is too much for my G540. I switched to 230 and it puts out 45v (all running on 110. is there something wrong ? Is my switch backwards?

    48vac rectified and filtered will output 48v*1.414 = 68vdc

    Not sure but I would drop them a line right away.If the switch was backward, I think you would get half the output voltage, except if is regulated it will try to output what is supposed to. I don't think I am making any sense

    If it is a keling power supply, I believe that the power supply is a regulated supply and should output 48v as delivered.

    "48vac rectified and filtered will output 48v*1.414 = 68vdc"

    Does that mean that this poer supply:

    KL-600-48 48V/12.5A 115V /230V

    will power this Servo:

    KL23-130-60
    Skewed Rotor Design, 60V/20A
    Constant Torque: 50 oz-in
    Peak Torque: 350 oz-in
    No load Speed: 4700 R.P.M
    Terminal Voltage : 60 VDC
    Continuous Current: < 4 A
    Peak Current: > 20 A
    No load Current: 0.5A
    Weight : 1.4 kg

    up to its max 4700rpm no load speed?

    I'm trying to figure out what gearing I need so I have to be sure that the power supply is up to the job of getting the servo up to its rated max rpm
