Introduction SE 3708C Power Supply Manual
1.3 CONFIGURATIONS
The SE 3708C Uninterruptable Power Module is identified by four different part numbers depending
upon the lock power output and the AC power input. These part numbers and the Power Module
configurations are shown in Table 1-1.

1.4 GENERAL INFORMATION
General information on the SE 3708C system operation and system applications is provided below.
1.4.1 SYSTEM OVERVIEW
The SE 3708C Uninterruptable Power Module is a true uninterruptable power supply in that it can take
power either from the power lines or from external storage batteries which are always on-line in case
the power fails. Normally, when AC power is available, the batteries are always kept charged; when
the power fails, the batteries take over immediately until AC power is restored.
To accomplish this, the 3708C is actually two power supplies working together. The first, or primary
power supply, provides low voltage for locks, for battery charging, and for the secondary power supply
which, in turn, produces all system voltages. During power outages, the batteries continue to provide
the low voltage needed for locks and the secondary power supply.
1.4.2 SYSTEM APPLICATIONS
The 3708C can provide enough power to run an access control system consisting of the following
components:
•
Up to 2 Access control unit(s).
•
Up to 16 Multiple Switch Monitor(s) (SE 774) or Door Switch Monitor(s) (SE770).
