Product Description:

The PSI63C0.759-L2 is a frequency inverter that is specifically developed for industrial automation. Made by Bosch Indramat, this inverter ensures a requisite power conversion in a 95% efficient manner. It is appropriate for motor and other machinery control because it has a rich range of protection functions to increase operational safety.

The PSI63C0.759-L2 Inverter Frequency functions at 80 A of current and outputs a power of 15 kW. It has a maximum efficiency of up to 95% under fully loaded operations. The maximum leakage current is rated at 35 mA making it safe for use in the market. This inverter is of 3 3-phase type and is used to provide a very efficient output for industrial usage. The conductor has a cross-sectional area of 25 mm² which provides an effective current carrying capacity. The PSI63C0.759-L2 Inverter Frequency needs an external fan for forced air cooling. This cooling method makes sure that there is adequate airflow on the inverter for correct operating temperatures, when used heavily the inverter may overheat. Its dimensions are fairly moderate namely 80×398×200mm which enables the unit to fit into small spaces. During usage, the output power is only 25 W making the efficiency of the system better.

The PSI63C0.759-L2 Inverter Frequency has some of the protective features that were formerly incorporated in it. It contains over-voltage protective, under-voltage protective, over-current protective, and thermal protection. It is implemented for automobile applications and meets the EMC Level A requirements. It offers less electromagnetic interference with the neighboring equipment. It is a type of motor controller developed with industrial applications in mind. This provides proportional and precise motor control and methods of safety for linked systems.
