APPLICATION
The Premium ODS-750 inverter is a 120Vac or 230Vac output dc ac converter. The frequency can be set to 50Hz or 60Hz via a DIP switch, the input and output are galvanically isolated.
The ODS-750 consists of two cascaded converters, one dc dc generating an intermediate output volatage from the input voltage. The intermediate voltage is then inverted to supply the output voltage and frequency by means of a dc ac converter.
The topology for the first converter is a fixed frequency push-pull type that provides the isolation between input and output. The second converter consists of a bridge inverter also at fixed frequencyand fully PWM controlled by means of a microcontroller that is equiped with an LC output filter that removes the switching frequency components and delivers a sine-wave output.
The ODS-750 inverter is equipped with input polarity protection by means of fuse. It also featues maximum average power protection as well as maximum output peak current protection. This protects the semiconductors even when an output short-circuit occurs. it also features a disable function for input undervoltage, which protects the batteries from harmful discharges.
Ten M3 threaded holes holes are provided for chassis mounting in different positions, with the optional base and 2 x DIN rail clips it can be mounted on a standard DIN rail.
The ODS-750-72xx-T version is designed for railway applications to EN50155; EN50121-3-2; EN50121-4.
