5.1.7 Regulation (Rectifier Module)

(A) Voltage Regulation: ≤±1%

(B) Load Regulation: ≤±0.5%

(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%.

5.1.8 Regulation (via MCA)

(A) Static: The 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 Rectifier Modules.

(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 limits specified in Paragraph 3.2.1 shall not

cause the output voltage to deviate outside the ±0.5% regulation band.

5.1.9 Filtering (with or without battery): Typical readings were taken at nominal input voltage,

nominal output voltage, 50% load, and 25 degrees C ambient.

(A) Voice Band Noise: Complies with Telcordia GR-947_CORE.

(1) Typically 20.4 dBrn C-message weighting. Does not exceed 32 dBrn C.

(2) Typically 0.28 millivolts psophometric. Does not exceed 1 millivolt psophometric.

(B) Wide Band Noise: Complies with Telcordia GR-947_CORE.

(1) Typically 55 millivolts peak-to-peak. Does not exceed 200 millivolts peak-to-peak

(2) Typically 15.9 millivolts rms. Does not exceed 100 millivolts rms.

5.1.10 Hold Up Time: 10 ms (The DC voltage is allowed to decrease to 42V from 54V during the test.)
