2.7.3.2 UPSC-DR<br />

Introduction<br />

This board combines the power supply and battery management functions. No other components<br />

are required if operated as a power supply. To maintain short-term battery emergency<br />

operation after a power failure, that is, to use uninterruptible power supply functions, you must<br />

also connect a battery pack.<br />

An EPSU2-R external power supply must be used if the total number of U P0/E stations, analog<br />

stations, and stations connected using adapters is greater than 72.<br />

Additional power can be made available by connecting the external EPSU2-R power supply<br />

(see Section 2.7.6) To do this, connect the DC port on the EPSU2-R to the special –48 V DC<br />

input on the UPSC-DR. The UPSC-DR’s internal -48-V output is deactivated when the external<br />

power supply is connected.<br />
