EATURES

High efficiency cost effective power supply ideal for use in Fire, Access Control and General Security

applications. Featuring a regulated 27.6Vdc output supplying continuous full rated current to load and up to

an additional 0.5A for charging 2 x 12V standby batteries, if fitted. The universal mains input voltage enables

the power supply to be used across a wide geographical area. The highly efficient switch mode design ensures

low operating costs, generates less heat and with a small physical size increases the room available for

additional PCBs or cables. The modular construction simplifies maintenance.

NSTALLATION

NSTRUCTIONS

This unit is only suitable for installation as permanently connected equipment. This PSU is NOT

SUITABLE for external installation. This unit must be fed from a mains power source having a separate

(approved) disconnect device and fitted with a fuse or other over current protection device rated at 3A

maximum. Ensure that the disconnect device used has appropriate earth fault protection to the

applicable standard.

EQUIPMENT MUST BE EARTHED. Before installation, ensure that external

disconnect device is OFF.The PSU should be installed according to all relevant safety regulations

applicable to the application.

Mounting

1) Mount securely in correct orientation allowing minimum clearance – see diagram.

2) Route mains and low voltage output cables via different knockouts and/or cable entry holes.

3) Use bushes and cable glands rated to UL94 HB minimum.

Mains Power Up

4) Attach correctly rated mains cable (minimum 0.5mm

[3A], 300/500Vac).Fasten with cable ties.

5) Apply mains power. Check for 27.6Vdc on load outputs. Check Green Mains LED is ON.

6) Disconnect mains power.

Load Output

7) Attach correctly rated load cable and fasten using cable ties. Note polarity.

8) Apply mains power. Check Green Mains LED is ON.

9) Verify load is operating correctly.

10) Disconnect mains power.

Standby Battery

11) Attach supplied battery cables to terminal block and batteries.

NOTE: ensure correct polarity of battery connections: Red lead to +ve of battery 1, Black lead to

ve of battery 2. Connect ve of battery 1 to +ve of battery 2 using short link lead

12) Position batteries to avoid lid fixing screw.

13) Apply mains power. Check Green Mains LED is ON.

14) Check there is no fault indication on Yellow Fault LED.

15) Disconnect mains power. Check that the batteries continue to supply voltage and current to the

load. Check Green Mains LED is OFF.

NOTE: Batteries must have sufficient charge to supply the load

16) Reconnect mains power. Check Green Mains LED is ON.

17) Remove Load fuse and check Yellow Fault LED is ON.

18) Replace Load fuse. Check Yellow Fault LED is OFF.

AINTENANCE

There is no regular maintenance required of the PSU other than periodic testing and replacement of

the standby batteries. Reference should be made to the battery manufacturer’s documentation to

determine typical/expected battery life with a view to periodic replacement of the battery.

If the output of the PSU fails the cause of the failure should be investigated e.g. short circuit load. The

fault should be rectified before restoring power to the PSU. The fuses may need to be replaced. Ensure

the correct fuse rating and type is used.
