STUDER INNOTEC COMPACT

2 Introduction

The COMPACT is a sine wave inverter with integrated battery charger and solar charger controller with many additional functions, it has been developed to be used as stand-alone (independent of a grid-system) AC provider, or as continuous / break-free current supply provider.

2.2Description of main functions

2.2.1The Inverter

The sine wave inverter built in the COMPACT generates a sinusoidal AC voltage with an exceptionally precise voltage and stabilized frequency. In order to start large electric motors, the user has the possibility to employ a short-start-power which is 3-times the nominal power of the

COMPACT.

The inverter is protected against overload and short circuit. A power-stage with the latest MOS- FET power transistors, a toroidal transformer, and a fast regulating system make-up a robust and reliable inverter with highest efficiency. A 1-20 Watt adjustable charge detection system serves to provide the smallest energy consumption and ensures a long life for the battery.

2.2.2The Transfer system

COMPACT can be connected to an AC source. For example a stand-by emergency generator or the AC network. With the transfer system, on one side you have an alternating voltage at the output for use by the connected consumer devices. On the other side the batteries are charged. The distribution of energy between the consumer devices and battery charger is automatic.

2.2.3The Battery charger

The built-in battery charger is so arranged that it can charge the batteries quick very completely. A microprocessor controlled, 3 to 4 Step charging process ensures the optimum charging of the batteries. The desired charging current can be set continuously from 0 – 55A (C 4000-48: 0 - 50A). The battery charger is meant for the lead-acid and lead-gel batteries. Thanks to the floating charge system the batteries can remain continuously connected.
