AC/DC Power Supply PowerPac 1200

The PowerPac 1200 is, as the name already implies, a compact AC/DC Power Supply and an intelligent battery charger in one, with a rated output of 28V/40A. It meets the most discerning mechanical and electrical demands on ruggedness and can handle great input voltage fluctuations. The input current of the PowerPac 1200 is power factor corrected (PFC) to ensure the optimal use of weak current sources such as portable generators. Its shunting switch technology allows for great power efficiency. When operated as a stand-alone unit or installed into a 19" rack system, it only takes up a height of 2U (88.9 mm/3.5"). The PowerPac 1200 comes with a RS485 port that can be used for control, monitoring, and configuration. This port can be used to access detailed status and statistical information. The signal connections offer various signals:

Alarm relay output, external battery temperature sensor, and a bus to connect various devices in a redundant or parallel system. The PowerPac 1200 can be configured to charge a diverse range of battery types, such as lead-acid, NiMH, and NiCd, as well as for future battery technology on the software side. Temperature-compensated charging ensures full battery capacity throughout the temperature range. The device is protected against overvoltage, short-circuiting, overcurrent, and excess temperatures. The 12V DC/DC module makes it possible to charge from two power sources. Depending on the setting, the more powerful source, e.g., a 12 V generator, 12 V battery, or the public power grid, is automatically switched on or off. If the 230 V mains is selected as the primary power source, the power-supplying 12 V battery can also be charged moderately.
