Features of the Power Supply Sources
SSG series.
The SSG1,5 SSG2,5 and SSG5 power supply sources have been
designed in accordance with standard EN54-4 to supply support
power to fire control systems.
The Series SSG power supply source has been designed to operate
with a universal input range of 90 to 264 VAC and frequencies
between 47 and 440 Hz. There is no need to change the voltage; the
source self-adjusts to the primary power supply conditions.
The two source models are similar; they are composed of a power
supply module of 45W , 65W and 2 x 65W for supply sources
SSG1,5 SSG2,5 and SSG5, respectively, and an electronic control
module that provides all primary and secondary (batteries) power
supply source supervision.
The power supply sources can supply up to 630 mA (SSG1,5), 1 A
(SSG2,5) or 2 A (SSG5) of current in each of their two outputs PS01
and PS02. If the sum of currents is needed to supply a single load,
the positive of both outputs should be connected in parallel:
The negative is common in the control board and thus does not need
to be bridged.
