The ComPact Dual Input is a compact DC power supply and battery charger with dual inputs, switching seamlessly between an AC and a DC power source, all while maintaining a stable DC voltage at the output. The AC input current is power factor corrected and designed for optimum utilisation of weak power sources such as portable generators. The DC input enables the unit to operate from the vehicle power. When powered from the AC source, the ComPact will charge any battery connected to DC output as well as the vehicle battery connected to the DC input, preventing self-discharge.

The RS-485 bus can be used for control, monitoring and setup. Detailed status and statistics can be retrieved. The bus is also used for interconnecting multiple units in a redundant or parallel system. The signal connectors provide alarm relay outputs and inputs for individual battery temperature sensors (battery both at the DC input and the DC output) in addition to the RS-485 bus. Temperature compensated charging ensures full battery capacity over the entire temperature range. The ComPact can be configured to charge different battery technologies, including custom specification. The firmware is user upgradeable for future battery technologies. The ComPact is protected from overvoltage, overcurrent, short circuit, reversed polarity (at both DC input and DC output) and over temperature.

Input Circuit Breaker The input circuit breaker is for failure protection and is also used as an ON/OFF switch. When switched “OFF”, the Compact Dual input will switch to the DC source.
Alarms Status signals are fed to seprate potential outputs, and are indicated in separate LEDs.
LEDs in the AC input section: Power OK, Error, Current limit
LEDs in the DC input section: Power OK, Error, Charge
Display The display can be toggled between output voltage, output current and alarm/error codes.
AC and DC Input Voltage When the AC voltage is below the safe operating range, the ComPact will switch to the 12 VDC source. When the AC input voltage returns to a safe level, the ComPact will switch back to the AC input.
