18 Specifications
UM5C06B / C ( 169-2071-500 ) P0711722 Standard 10.00 May 2001
Output voltage
Floating: -46 V DC to -57 V DC
Equalizing: 0 to -2.5 V DC above float
Output regulation: At the point of regulation: within +0.5% of the
selected value for all specified input and output
variations and within +1% for any combination of
specified input, output and environmental conditions.
Output protection: 30 A DC breaker
Output current: at 96-132 V input * - 15 A for MPR15E/EX at 176-
264 V input – 25 A for MPR25E/EX
Current limit: 17.5 to 20 A minimum for 96-132 V input and 25.5 to
30 A for 176-264 V input. From -46 V DC to -57 V
DC. Constant power for output from -57 V DC to -
59.5 V DC
Note: The AC inrush current during the turn-on sequence of
the rectifier, under all input and output conditions
specified in this document, will not exceed its full load
steady-state value.
Output noise and ripple
• less than 22 dBrnC at voice frequency, with batteries measured at the
point of regulation and over the entire range of the rectifier, inducing
operation in the current limit mode, and low nominal and high input
conditions.
• less than 10 mVrms in any 3 kHz band between 10 kHz and 20 MHz.
Measurements made with or without batteries at the output terminal of
the rectifier and with the rectifier in the local sensing mode.
•
peak-to-peak switching voltage spikes less than 250 mV (600 mV
from -40°C to 0° C), measured differentially with an oscilloscope at a
2 MHz bandwidth.
