Overview of Equipment
3.1 Description
The Ampcontrol CPS-A Intrinsically Safe Compact Power supply forms part of the Gasguard Range of Group I certified Gas
Detection and Alarm Systems and is also suitable for use with other applications.
The CPS series of IS power supplies convert 110Vac mains power to intrinsically safe low voltage DC power.
The DIN rail mount enclosure is made of robust black polycarbonate. Top and bottom enclosure walls have ventilation slots for
natural convection cooling. The side walls are solid and allow other components to be mounted adjacent to it on the DIN rail. Top
and bottom ventilation slots must be kept free for air circulation. Screw terminals are located on the front for connecting the AC
mains cable and the output load circuits. The output has two terminals for each of the positive and negative DC supply.
WARNING!
The power supply must be mounted in a safe area or in a suitable enclosure with a minimum
IP 54 rating.
Typical use of this power supply is for voice communication systems, gas detection systems and other electronic equipment
requiring intrinsically safe power in a Group I application.
The CPS-A Power supply is an IP 20 plastic enclosure DIN rail mounting Intrinsically Safe power supply designed for Group I
applications. Several power output versions of the Power Supply are available with a range of voltage and current limits.
Mounting is by a moulded clip assembly onto a standard TS32 top hat DIN rail.
Connections are made to enclosed screw clamp type terminals on the front facia of the enclosure.
