PowerPac 2400 AC/DC

Battery charger / power supply unit 2400 W

The PowerPac 2400 is a modular, compact AC/DC power supply and an intelligent battery charger in one, with a rated output of 28 V / 80 A. It meets the most discerning mechanical and electrical demands on ruggedness and can handle great input voltage fluctuations. The PowerPac 2400 input current is power factor corrected (PFC) for optimal use of weak power 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 2400 comes with an 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 provide multiple signals: alarm relay outputs, external battery temperature sensors, and a bus for connecting multiple devices in a redundant or parallel system. As such, the output power can be cascaded to 4.8 kW, 7.2 kW, and so on. The PowerPac 2400 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.
