Lucent Technologies ECS Minicell Battery Plant H569-420
2 - 4 Product Description
Issue 5 February 1997
Notes
1. If a panel is expected to operate continuously in an
ambient temperature of 40° C to 50° C, the total current
draw through the panel cannot exceed 500 amperes.
2. The H569-420 Group 1 can accommodate 2 rectifier
shelves and one converter shelf. In the H569-420 Group 2,
the converter shelf takes the place of the second rectifier
shelf.
3. For altitudes of 5000 to 13,000 feet, derate maximum
temperature by 3.6° F per 1000 feet above 5000 feet. For
altitudes of 1524 meters to 3962 meters, derate the
maximum temperature by 0.656° C per 304 meters above
1524 meters.
4. Specified at 27.25 volts dc, 600 amperes output, and
nominal input voltages and frequencies.
5. Measured at 2 feet (0.6 meter) from the rectifiers installed
in a plant.
Safety Agency
Approvals
The H569-420 bay is Underwriters Laboratories (UL) Listed per
Subject Letter 1801, Power Distribution Center for
Communications Equipment. Rectifiers are individually UL
Recognized (UL1950) and CSA Certified (CSA 22.2234) or
equivalent.
Typical Battery
Plant
A basic block diagram of a typical dc battery plant is shown in
Figure 2-1. The battery plant accepts alternating current from the
commercial utility or a standby ac power source and rectifies it
to produce dc power for the using equipment. The plant’s control
and alarm functions interact with the rectifiers and the office. In
addition, the plant provides overcurrent protection, charge,
discharge, and distribution facilities. Battery reserve
automatically provides a source of dc power if the commercial
or standby ac fails. This battery reserve is engineered to supply
dc power for a specific period of time. In normal practice, battery
capacity is sized to provide 3 to 8 hours of reserve time.
Battery Plant
Subsystems
AC Input: connects the commercial and/or standby ac power
sources to the rectifiers within the plant and provides
overcurrent protection. This subsystem is usually supplied by
the customer.
