4. Basic Functions and Technical Description
The PSU gets 220 VAC, 50/60 Hz from the mains and provides 24 VDC at the output. The
PSU circuitry includes a step-down transformer, an electronic rectifier, emergency supply switching
circuits and an output for an external alarm unit.
In addition to the mains, the BATT terminals of the PSU are powered from standby sources or
from rechargeable batteries so as to ensure trouble-free operation of the equipment connected to the
PSU.
The PSU will be switched over to a standby source automatically if the main power source
fails, is turned off or is unavailable at the PSU. If there is a failure in the input power supply, dry
contacts of the relay open and an alarm signal of the PSU is generated in response to that. The
OUT_ALARM terminal block is powered from rechargeable batteries in order to feed the external
alarm unit. Thus, no additional supply circuit powered from another source is required for the alarm
unit.
There is a circuit breaker to protect the PSU from any short circuit that may occur in the
output circuit. If the PSU is switched off due to a short circuit, it will be necessary to eliminate the
cause of such short circuit and switch the circuit breaker on.
5. Installation and Connection of the PSU
1) Install the PSU on a vertical bulkhead or on a mounting panel as shown in the dimensionand-installation drawing (Fig. 1). There are special holes in the PSU body to attach the PSU. The
fasteners (such as screws and bolts) are fitted inside the body.
2) Connect cables of external devices and power supply sources to the PSU terminals as
shown in Fig. 2.
3) Switch on the PSU with the switch that is on the side panel of the body.
4) Make sure the PSU is working properly (feed output power to the equipment connected to
the PSU).
