Regulation:
a) Output Voltage Tolerance:
Output voltage tolerance:
< ± 0.2% 25A load +15°C - +35°C
< ± 0.5% 25A load -5°C - +55°C
Static regulation, including input voltage variation and temperature variation:
< ± 0.5% 5-100% load +15°C - +35°C
< ± 1% 5-100% load -5°C - +55°C
Uin = 176-290 Vac, f = 45 Hz - 65 Hz
Output voltage decreases with increased output current.
Overshoot of output voltage at startup ≤ ±1%.
b) Dynamic Response Characteristic (at rated input and output voltage):
Response time ≤ 200us and overshoot ≤ 5% for load changes at
50% - 25% - 50% and 50% - 75% - 50%.
Overshoot or undershoot ≤ 5% and output recovers within ±1% of regulation
band in ≤ 4ms for load changes at 10% - 90% and 90% - 10%.
(Telcordia GR-947.)
Filtering (with or without battery):
a) Voice Band Noise: Complies with Telcordia GR-947-CORE.
1) Output noise according to Telcordia GR-947-CORE: < 32dBrnC between
180V~290Vac input and 10 - 100% load (output voltage > 42V, for any
application with > 1 Rectifier).
2) Psophometric noise is ≤ 1mV between 180V~290Vac input and 10 -100%
load (output voltage > 42V) and 16.66-6000Hz. (for any application with > 1
Rectifier).
b) Wide Band Noise: Complies with Telcordia GR-947-CORE.
1) Typically 130 millivolt peak-to-peak. Does not exceed 250 millivolt peak-to-
peak.
2) Typically 13 millivolts rms. Does not exceed 30 millivolt rms.
Output Discharge: The output capacitors automatically discharge when the
Rectifier is disconnected from the batteries and AC is turned OFF. Time constant is
less than 1 minute.
Power Interruption: The Rectifier starts when connected to a fully discharged
battery or capacitor bank (bus voltage > 15V) without operating protective devices or
requiring the shedding of load or needing any manual intervention. The Rectifier
starts under all line and environmental conditions, when the output terminals are
connected to an impedance of less than 15 milliohms.
Stability Criteria: Complies with GR947 Core R3-20. Stability criteria: > 30 deg. of
phase margin when gain is unity (0 dB) and gain down to < - 6 dB when phase is 180
deg.
