PS2
1. OVERVIEW
1.1 Introduction
The PS2 is XPR's unique power supply unit, which is fully compatible with XPR products. It has sufficient capacity to power readers,
EM locks or strikes, in addition to the Controller EWS. It provides stable DC output even with varying input voltages. It comes in a
strong and elegant steel housing. It has a built-in charger circuit and an option to house a battery for backup, in case of power failure.
The PS2 has built-in automatic protection against battery over-charging. It also has built-in over voltage and surge protection.
This ensures highly stabilized power output even at fluctuating input voltages.
1.2 Features
- Switched Mode Power Supply.
- Steel housing.
- In-built battery charger.
- Provision for battery for backup power.
- Fuse protection for mains input.
- Fuse protection against battery polarity reversal.
- Short-circuit and output overload protection.
- Tamper protection.
- Protection against battery over-charging.
1. 4 General information
PS2 is specifically designed (intended) for use as a
reliable power supply for access control systems.
2. INSTALLATION
2.1 Mounting instructions
1. Identify a suitable location to mount the PS2.
2. Separate the top cover of the PS2 carefully from the base plate.
3. Stick the drilling template provided onto the wall and drill 5 holes as indicated in the template. Four holes are for fixing the base
plate to the wall and the 5th hole is to fix a bush for the tamper.
4. Insert the 6 mm wall plugs (5 nos provided) into the drilled holes.
5. Place the round blackened bush (provided) on the hole drilled in the central part of the template, and fix it to the wall with the
screw provided.
6. Ensure that PS2 unit is grounded properly (Refer Section 2.2).
7. Route the cables through the holes in the base plate and fix the base plate to the wall using the screws provided.
8. Wire the PS2 referring Section "2.3 Overall PCB view" as a guide.
9. Place the battery (not provided) in place & ensure proper connection.
Note: For Battery connection, the wires on one end are already connected to PS2 and the other end of the wires have clips
for battery connection.
Caution: Please observe correct polarity, as otherwise the fuse may blow.
10. Place the top-cover against the wall over the base plate, and slide it down to lock it in place.
11. Fix the top cover to the base plate with 2 screws (M3x6mm security screw) at the bottom, using the security screwdriver provided.
2.2 Earthing
Several layers of protection are provided against transient voltages from static discharge, lightning and power supply spikes. For
protection to be fully effective, earthing of the housing should be done properly (XPR recommends common earthing for PS2, O2LA
and EWS) Use 16 AWG or heavier cable and keep the cable length as short as possible.
