Charger Rating (x2)
1.00 Amp (min) – temperature-compensated, lead-acid battery
charger.
Continuous Power supply
Output Rating (x 2)
100W total available across 2 outputs:
25V Supply (General System)
2.25A (55W) max.
1
35V Supply (Loop Driver feed only ) 2.50A
(85W)
max.
0.75 Amps from the 25V supply is reserved for powering Internal
circuits. The remainder of available power is for external loads
(Conventional sounders, Aux supply & loop current).

25.5V Max & 20V Min .
Maximum Ripple Voltage
<0.5V peak-peak on both 25V and 35V outputs.
Battery Charger Outputs (x2)
27.4 V nom at 20°C (temperature compensated).
Quiescent current
250mA + loop driver / option card c external circuits.
Alarm current
490mA + loop driver / option card c external circuits.
3
Standby Batteries
24V sealed, lead acid.
Minimum Capacity - 12 Ah (x4).
Maximum Capacity - 24 Ah (x4).
Printer Supply
8-9V AC from integral mains transformer for optional panel-
mounted printer (to be supplied from upper ZX5Se unit only).
Table 14 – ZX10Se Power Supply and Charger Specification
1
Making use of the 35V output, to supply the loop driver cards directly, avoids the overall restrictions associated with loop
supply on the ZX10Se.
2
Output = Battery voltage – 1.0 volts under mains power failure conditions.
