Power Derating Based on Input Voltage: See Figure 2.2.
Figure 2.2 Output Power vs. Input Voltage
Regulation (Rectifier Default):
a) Voltage Regulation: ≤±1%
b) Load Regulation: ≤±0.5%
c) Line Regulation: ≤±0.1%
d) Overshoot at Startup: ≤±1%
e) Dynamic Response (at rated input and output voltage values):
Response time is ≤200 µs, and the overshoot is ≤5% for load changes at 50%-25%-50% and 50%-75%-50%.
Overshoot or undershoot is ≤5% and within ±1% of the regulation band, ≤4 ms at 50 µs for load changes at 10%-90% and
90%-10%.
Regulation (via system MCA)
a) Static: The Power System MCA controls the steady state output voltage to within ±0.5% of any voltage setting within the
range of 44.0 to 58.0 volts DC for any and all combinations of load from no load to full load, input voltage, and input
frequency at a constant ambient temperature. If the MCA's regulation feature is disabled for any reason, steady state
regulation is ±1.0% as controlled within the Rectifiers.
b) Dynamic Response: For any step load change from 10% to 90% or from 90% to 10% of full rated load within 250
microseconds, shall not cause the voltage measured at the output to overshoot or undershoot more than 5% of the regulated
output level within 1 millisecond. The output voltage must return and stay within the ±1% regulation band within 4
milliseconds and within the ±0.5% regulation band within 3 seconds.
Any step change of the line voltage within the range of 260 to 530 volts shall not cause the output voltage to deviate outside
the ±0.5% regulation band.
