Power Derating Based on Temperature
• Regulation:
a) Static: Steady state regulation is ±0.6% as controlled within the rectifier for any and all combinations of
load from no load to full load, input voltage, and input frequency at a constant ambient temperature.
With controller, the output voltage shall remain within ±0.5% of the set point over the specified ranges of
input line voltage, output load current and ambient temperature.
b) Dynamic: Response time ≤200 microseconds and overshot ≤5% for load changes at 50% - 25% -
50% and 50% - 75% - 50% at rated output voltage and current.
For any step load change within the range of 10% to 90% of full load within 1 milliseconds, per
Telcordia GR-947-CORE, the maximum voltage transient will not exceed 5% of the initial steady
state voltage within 250±10 microseconds. Recovery to within 1% of the initial steady state voltage
does not exceed 4 milliseconds.
• Filtering:
a) Voice Band Noise: Complies with YD/T-731-2008.
1. Peak-peak voltage is ≤200 mV at 0 MHz - 20 MHz and normal output voltage. (YD/T-731-
2008)
2. Psophometric noise is ≤2 mV typical at 220 VAC input, 53.5 VDC output and 20% to 70% of
rated load for more than one rectifier.
b) Wide Band Noise: Complies with YD/T-731-2008.
1. Wideband noise emission is < 20 mV between 25 Hz - 20 kHz according to ETS 300132-2.
