Reply to "UPDATE 1/31/20: Postwar ZW operating question"

owned 5 pw ZWs over time and never saw one produce over 10-11 maximum amps under load. Current surges can change the railpower environment, but the published high wattage rating on the pw ZW is input not output.

Try setting  B to 19 volts and C to 6 volts, measure the voltage difference between them.  Then put a 1 ohm (or zero) resistance load across the two posts with a 0-100 amp ammeter in series with the load and see just what the ZW is capable of in unprotected mode(no 14 amp circuit breaker).

I've done this, and with just a 7-8 volts difference in throttle settings, the 0-30 amp ammeter was pegging / off the scale.
