    Remote Sense Efficiency Start-up Delay Rise Time Transient Load Response

    48V output: Compensates for voltage drops to 0.5V between the power supply to the load. Outputs are internally sensed at output connector if remote sense lines are opened. 230Vac, full load 115Vac, full load Output voltage at 90% For load change 75%, at slew rate of 1A/µs, recovery time less than 2ms Single wire current share a N+1 parallel redundant configuration with OR-ng diodes included in the PSU Available 110Vac, full load Voltage change at turn-on and turn-off ms %
