SATEL APS-15 3
TEST BAT – enable / disable the battery status control (jumper ON – enabled, jumper
OFF – disabled). Disabling the battery status control turns off the battery
trouble signaling on the AWA output.
red LED indicating the AC mains power supply status:
ON – AC power OK,
flashing – no AC power.
green LED indicating the battery status:
ON – battery OK (or the battery status control disabled),
flashing – low battery (battery voltage below 11 V).

Description of terminals:
AC – power input (17-20 V AC).
COM – common ground.
+12V – power supply output (13.6-13.8 V DC).
AWS – OC type output indicating loss of 230 V AC power.
AWA – OC type output indicating low voltage or failure of the battery.
TMP – tamper output (NC).
In the normal state, the OC type output is shorted to common ground (0 V). In the active state (trouble
signaling), the output is disconnected from common ground.
4. Installation
Disconnect power before making any electrical connections.
Before installation, prepare a load balance so as not to overload the power supply. In
normal operating conditions, the sum of currents consumed by the connected devices
and the battery charging current must not exceed 1.5 A.
The power supply has been designed for use with lead-acid batteries or other batteries
having similar charging characteristics. Using other batteries than the recommended
ones may cause an explosion.
The used batteries must not be discarded, but should be disposed of in accordance
with the existing rules for environment protection.
The transformer should be permanently connected to the 230 V AC mains supply. Before you make
the cabling, familiarize yourself with the electrical installation of the facility. Make sure that the circuit
you choose for powering will be always alive. The circuit should be protected with a proper safety
device. The owner or user of the power supply should be instructed on how to disconnect the
transformer from the mains (e.g. by indicating the fuse which protects the supply circuit).
A 12 V lead-acid sealed battery can be connected to the power supply as a backup power source.
The power supply enclosure can accommodate a battery with 9 Ah or 7 Ah capacity.
If the power supply is to be installed in another enclosure (e.g. SATEL made OPU-3 P or
OPU-4 P), skip the steps from 1 to 5 and mount the electronics board as recommended in the
installation guide for the given enclosure.
