Overview
The PTC is a combined Power Supply and Battery
Charger system with integrated standby battery
management for small uninterruptible instrument supply
applications.
Just connect mains supply, standby battery and load for
an industrial grade standby power supply system.
This DIN rail mounted product is ideal for providing dc
power to Teleterm M2-series RTU systems where battery
backup is necessary to ensure continuous system
operation during power failure. Applications include
RTU’s, data-loggers, remote field instruments, alarm
systems and access controllers.
Managing battery-backed systems for optimum backup
time and battery life can be tricky and expensive.
This product incorporates many features that make
installing such systems simple and foolproof:
Under-voltage Cut-Out
During prolonged power outages, the back-up battery will
eventually discharge. If the load remains connected, the
battery enters its “deep” discharge phase, which can

cause irreparable damage to the battery, and reduce its
capacity and life. The PTC incorporates an under-voltage
cut-out that disconnects the load when the battery
voltage begins to fall, preserving the battery life.
Fault Protection
Batteries are capable of delivering enormous currents
under system fault conditions that can damage wiring
and equipment. The PTC incorporates an auto-resettable
load cut-out, which disconnects the load under overcurrent fault condition.
Charge Control
The PTC controls the charging of the battery to ensure
optimum life. Batteries can be kept on continuous charge
as long without fear of damage through overcharging.
System Monitoring
The PTC provides an AC detect output. When AC is
present and the supply is functioning correctly, this output
is on. This output can be used to detect AC input or
charger failures.
