This DIN rail mounted combined PSU/Battery back-up system from Omniflex is ideal for providing 12 or 24Vdc power when mains power is not available. Applications include RTU’s, data-loggers, remote monitoring systems, alarm systems and remote access systems, to name just a few.
Just connect a solar panel, sealed lead acid battery and load for an industrial grade solar powered Power Supply battery Back-up system.



The powerterm PSU/charger family is renowned for being a product range that can be depended on. This latest addition to the family continues with the tradition. The PTS is manufactured using carefully selected long-life components and conservative design parameters to ensure increased reliability.



The POWERTERM PSU/Charger range offers a complete solution for small battery-backed dc instrument power system in a single compact package and is equipped with the following features:-



Under-voltage Cut-Out

In the event of complete discharge of the battery, an under-voltage cut-out disconnects the load preventing the battery entering its “deep” discharge phase, which can cause irreparable damage to the battery, and reduce its capacity and life.



Fault Protection

Batteries are capable of delivering very large currents under system fault conditions that can damage wiring and equipment. The PTS incorporates an auto-resettable load cut-out, which disconnects the load under over-current fault condition.



Charge Control

The PTS controls the charging of the battery to ensure optimum life. When the battery is fully charged, the PTS will disconnect the solar panel to prevent overcharging.



System Monitoring

The PTS provides a Charge detect output. When the solar panel is connected and charging, this output is on. This output can be used to detect solar panel or charger failure, or to measure actual charging hours.



12/24V Selectable output

The PTS can be used in 12V or 24V applications. The PTS can be switched to the correct battery voltage and adjusts the solar regulator and low voltage cut-out accordingly.



Temperature Compensation

In outdoor environments, the ideal battery voltage will vary with temperature. The PTS has a temperature sensor that compensates for changes in ambient temperature to keep the battery at its optimum.
