DIN Rail mounting
Available in 12Vdc or 24Vdc output versions.
Operates from 115Vac or 230Vac supply
4 Amp continuous load – (10Amp peak)
Under-voltage cutout to protect battery from deep
discharge.
Charging characterised for sealed lead-acid cells.
Independently current limited battery charging for
optimum battery life.

OVERVIEW
The PT5000C is a combined Power Supply and Battery
Charger system with integrated standby battery
management for small uninterruptable 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 instrument systems where battery backup is
necessary to ensure continuous system operation during
power failure. Applications include RTU’s, dataloggers,
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.

Over-current protection to protect wiring against
faults.
Charger shutdown input for battery testing.
AC detect output for mains monitoring.
Optional temperature sensor for optimum battery
float voltage control in wide ambient operating
environments.
Independent battery and load terminals for ease of
installation.
PROTECTION
Batteries are capable of delivering enormous currents
under system fault conditions that can damage wiring
and equipment. The PT5000C incorporates an autoresettable load cutout, which disconnects the load under
over-current fault condition.
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 PT5000C incorporates an undervoltage cutout that disconnects the load when the battery
voltage begins to fall.
Batteries can be kept on continuous charge as long as
the charging current and float voltage are kept below
their specified maximum values. The maximum charging
current is based upon the Ampere-hour capacity of the
battery. This is can be less than the rated load current
depending upon the capacity of the battery chosen. The
