Hopkinton, MA – Schaefer Inc. is proud to unveil turnkey inverter systems using our Series IT of single or three-phase switch mode inverter systems with a power range from 6kVA to 90kVA. These highly reliable, fully-customizable "built-to-project" dc/ac pure sine wave inverters offer the industry's most complete range of input and output voltages, with a selection of package styles and mounting configurations. Some of our highly advanced designs feature an integrated UPS, static switch, battery charging and/or parallel capabilities.
The Series IT is fully isolated using a switch mode inverter with a rectifier at input and a transformer at the output. Features include continuous short-circuit protection, automatic restart after over-voltage shutdown and surge capability. Optional features include remote on/off via various inhibit configurations, input inrush and surge protection, mains synchronization, input reverse polarity protection, output voltage adjustment potentiometer, output voltage and frequency monitoring, increased mechanical strength, tropical (conformal coating) protection, parallel and redundant operation.
Available as a complete system including cabinet, front panel meters, breakers, switches, and ventilation with or without temperature controlled fans, etc. or as a standalone inverter. They are ideal for 600-750VDC nominal bus and are available for 40V DC+ as well as single or 3 phase AC inputs as well. Ideal for power sub-stations, emergency lighting and other backup systems.
IT Systems are custom-tailored to meet your specific application requirements. Full product specifications can be viewed at www.schaeferpower.com. For further information, please contact Schaefer, Inc., 45 South Street, Hopkinton, MA 01748. Tel: 508/435-6400 Fax: 508/435-6401.
