Model C2175A PT1000C 24Vdc PSU/Battery Charger - 1

PT1000C PSU/Charger Model C2175A (500 mA load/500mA Charge) Power Supply/ Battery Charger • A Complete solution for small battery-backed dc instrument power systems. • Supply 12Vdc or 24Vdc systems with continuous power during ac line interruptions without the need for inverters or mains UPS’s • Ideal for RTU’s, dataloggers, remote field instrumentation, alarm systems, remote access systems etc. Features • • • • • • • DIN Rail mounting Available in 12Vdc or 24Vdc output versions. Operates from 85-264Vac universal ac supply 500 mA load plus 500mA charge current 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 PT1000C 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.

Temperature compensated 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 PT1000C 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 PT1000C 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 http://www.omniflex.com ©

Model C2175A PT1000C 24Vdc PSU/Battery Charger - 2

PT1000C PSU/Charger Model C2175A (500 mA load/500mA Charge) Power Supply/ Battery Charger to allow the batteries to be tested in location. A charger shutdown input is provided. On activating this input, the charger is disconnected, allowing the battery voltage under load to be measured. By monitoring this voltage over a short time for any droop, the state of health of the battery can be determined. A unique safety feature prevents the supply from being removed completely in case the battery is faulty or has been removed. The power continues to deliver at a lowered voltage level during this...

Model C2175A PT1000C 24Vdc PSU/Battery Charger - 4

PT1000C PSU/Charger Model C2175A (500mA load/500mA charge) Power Supply/ Battery Charger Application Notes BATTERY SELECTION The PT1000C is designed to operate with sealed lead acid type batteries also known as Valve Regulated Lead Acid (VRLA) batteries. This type of battery is sealed except for a valve that opens when the internal gas pressure exceeds the design limits. (That is why it is important not to overcharge VRLA batteries). Generally, these batteries can be used in confined areas and can be mounted in any orientation. (see the specific manufacturer’s data for details.) There are...
