The
PSC-series pcb type of power
supply is specially designed for low cost applications in the
security industry. Designed by a high performance switching
technology, the efficiency is up to 88% and can therefore work in 70oC
temperature conditions by only free air convection.
This series possess full alarm signals in compliance to the
demand of security systems, including AC OK and a battery low alarm.
When the utility supply is off and the system goes into battery
backup mode, the relay will change state and a signal will be sent
out for an early reaction situation. If the battery voltage drops
below 11V (for a 12V battery bank) or 22V (for a 24V battery bank),
another relay alarm signal will activate the "battery low"
situation.
The battery backup loop will be cut off, when the
battery voltage drops below 10.5V or 21V to prevent batteries from a
deep discharge condition. Protection for the PSC-100 includes short circuit,
overload, and over voltage protection (by fuse) and battery low
cut-off for the battery side.
Suitable application are security systems, access control
systems, emergency lighting systems, alarm systems, UPS systems, and
central monitoring system.
