[Milsurplus] PP-4763 and Starting current

[J. Forster]

Measure the resistance of the input side with the dyno stopped. Then the
LRC is:

Supply Volts / Resistance = LRA.

> A question for the group:
>
> I'd like to use the PP-4763 to run a 24V TCS Motor-generator set.  The
> set has two 24V 1/3 horsepower motors rated together at 17A FLC.  The
> stock PS won't start even one motor.
>
> Has anyone had any luck disabling the current limiter (crowbar)
> circuit in the  power supply?
>
> Adding two tractor batteries in series across the power supply gave me
> enough capacity to start the receiver motor, but when I flip the
> switch for the transmitter, the PS current limiter still trips and
> shuts the whole thing down.
>
> I realize that LRC could easily be ten times the 17A listed for the
> two motors, but it seems that any large dynamotor (such as the HV dyno
> in the T-195) would have similar characteristics.

> Anyone had similar problems?
