13.8Vdc Switch Mode Power Supply

GEN2-08-y

for 8Ah Battery and up to 1.0A* Continuous Load Current

GEN2-18-y#

for 18Ah Battery and up to 1.5A* Continuous Load Current

EATURES

High efficiency cost effective power supply suitable for use in systems designed to comply with PD6662:2010 and EN50131-6:2008 Grade 2 and Environmental Class II requiring 8Ah or 18Ah standby battery capacity. Two independent output signals are provided for loss of mains fault (EPS**), and general fault (including APS** fault). Self-diagnostics can detect blown output and battery fuses and low battery voltage (APS fault). The PSU incorporates a battery management system comprising low battery voltage detection and deep discharge protection to ensure that the battery is not permanently damaged through excessive discharge. A brownout filter ensures that short mains voltage dips do not create a false loss of mains alarm. Two LEDs assist with quick and easy installation by showing presence of mains, correct battery charging and a fault condition. Comprehensive protection is built-in as standard including mains transient filtering, electronic output overload protection and fuses on the load and battery outputs.

Mounting

1) Mount securely in correct orientation allowing minimum clearance – see Fig. 1.0.

2) Ensure that the rear tamper is not in a position that will affect its operation, for example over a mortar

course, recess or raised area on the wall.

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

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

Mains Power Up

5) Attach correctly rated mains cable (minimum 0.5mm2 [3A], 300/500Vac). Fasten with cable ties.

6) Apply mains power.

Check for 13.8V on load outputs. Check green Mains LED is ON.

7) Disconnect mains power.

Load Output

8) Loop correctly rated load cable through supplied ferrite (1 turn) and attach to terminal block, note

polarity. Fasten with cable ties.

PERATING INSTRUCTIONS

In the event of loss of mains, a battery fault or a GEN fault, the corresponding Fault signal contacts will open.

If the output of the PSU fails, the cause of the failure should be investigated e.g. short circuit load, connection of a deeply discharged battery. The fault should be rectified before restoring power to the PSU. If any of the fuses require replacing, ensure the correct fuse rating and type is used.

AINTENANCE

Maintenance

This unit is intended for use by Service Personnel only. There are NO USER SERVICEABLE parts inside.

There is no regular maintenance required of the PSU other than periodic testing, and replacement of the standby battery. Reference should be made to the battery manufacturer's documentation to determine
