2000 50A -48V 364A-3 SR Series Rectifier
2 - 10 Product Description
Issue 6 January 1997
Dynamic Response: Using a battery having an ampere-hour
capacity (8-hour rate) four times greater than the output rating of
the rectifier, step changes in load over the range of 10 to 90
percent, or 90 to 10 percent, will not cause the voltage measured
at the point of regulation to overshoot or undershoot more than
5 percent. After the step change, the voltage will return to and
stay within the regulation band within 300 milliseconds.
Shipping: The rectifier in its shipping container will withstand
the vibrations and shocks normally encountered in shipping
without damage or degradation of performance.
Typical Battery
Plant
Figure 2-1 shows a basic block diagram of a typical dc battery
plant. 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.
Rectifiers: convert an ac source voltage into the dc voltage level
required to charge and float the batteries and to power the using
equipment.
Controller: provides the local and remote control, monitor, and
diagnostic functions required to administer the battery plant.
Batteries: provide energy storage for an uninterrupted power
feed to the using equipment during loss of ac input or rectifier
failure.
Note
Although all other specified characteristics remain within
limits, the presence of a battery does alter both the output
noise and transient response of the rectifier.
