Heavy-duty sine wave inverters deliver 400VA output voltage

 

A series of heavy-duty, high input voltage DC/AC sine wave inverters has been released by ABSOPULSE Electronics. The CSH-400-F6 units use microprocessor controlled, high frequency PWM technology to deliver 400VA pure sinewave output voltage. 

They convert 600VDC industrial input voltage (450-800V operating range) to an isolated sine wave output of 115VAC continuous at 60 or 400Hz, or 230VAC continuous at 50Hz. The design topology allows for input voltages of up to 1,200VDC. The inverters are designed for industrial applications that require clean sine wave AC-output voltage and are suitable for industrial automation and control, transportation, power plants and electrical utilities.

The high frequency conversion enables high efficiency, compact construction of 210x64x365mm and low weight. The inverters are cooled by conduction via baseplate and by natural convection through the cooling slots. Most heat generating components are installed on aluminum heatsink blocks which are thermally connected to the base plate. This also ensures mechanical ruggedness. The internal boards are conformal coated to provide protection against humidity and airborne contaminants. The units are typically chassis mounted.

The input meets EN55022 Class A with wide margins, with Class B available on request. This ensures that the inverters can be used in EMI sensitive environments without additional filtering. An optional output-fail alarm (Form C) is available. The units are designed for compliance with C22.2 No. 107.1 – 01, UL 458 and EN/UL60950-1 standards. Electronic protection includes input surge clamping, overload and short circuit protection, as well as thermal shutdown with automatic recovery. Large design headroom and the exclusive use of components with established reliability contribute to a high MTBF.
