UBPSU5.0 POWER SUPPLY
The UBPSU5.0 power supply is a 5A unboxed PSU with a regulated output voltage of 13.8Vdc. There are
four fused outputs that use 20mm glass ‘quick blow’ fuses. The standard fuse rating for each output is as
follows: output1 (LED1), output 2 (LED2), output 3 (LED3) = 1A, output 4 (LED4) = 3.15A, however, these are
interchangeable so that dierent fuse values can be used providing the overall current output rating does
not exceed 5A. It also includes a battery back-up facility with a battery trickle charge fuse of 1A. The DC
output terminals and battery trickle charge terminals are independently fused.
The power supply has an inline fuseholder (with pull-up latch for easy fuse replacement) that is used to connect
230Vac mains input. The inline fuseholder also uses a 20mm glass ‘quick blow’ fuse with a current rating of
T3.15A/250V.
IMPORTANT NOTE: The 230Vac mains input terminals on this PSU should be connected to the mains supply
via a fused spur or preferably an all pole circuit breaker (refer to pages 30 - 31).
UBPSU5.0 Dimensions
Each fused output and fused battery back-up connections includes a status LED to indicate when there is a
fault with the output (when the LED is ON this indicates the output is ok, when the LED is OFF this indicates the
fuse is damaged or blown).
Terminal Connections
The battery back-up connection wires use insulated crimp connectors (red = +pos, blue = -neg) for easy
connection to a 12Vdc battery. It is recommended that a 12Vdc, 7.0Ah valve regulated lead-acid type battery
is used (Videx part no. NP7-12).
