Inverters/Frequency Converters with Selection of Communication Interfaces

Schaefer Inc. announce the CI, IT, IV, and K Series of single or three-phase heavy industrial and military inverters and frequency converters with CAN, Ethernet, Modbus and Analog communication interfaces for mission critical applications. These highly reliable, fully-customizable "built-to-project" pure-sine-wave inverters offer 10Vdc to >1,000Vdc+ input voltage and 200VA-3MW outputs. Some of the designs feature an integrated UPS function, static switch (SS series), battery charging (B series) and/or parallel capabilities (N+1).

Features include continuous short-circuit protection, automatic restart after over-voltage shutdown and surge capability. Operating temperature is -20 to +75 degrees C, with -40 degrees C as an option. Optional features include ac or dc inputs and ac or dc outputs, Multiple output voltages, 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, low and high IP rated, liquid or air-cooled, parallel and redundant operation. Heavy industrial and military versions are available.

Safety and construction protection is in accordance with EN 60950-1/EN 50178. EMI to EN 61000-6-4, class A, option class B available. Optional: Mil-Std-1399 type 1 and type 3, Mil-Std-461, Mil-Std-1275, Mil-Std-1332, Mil-Std-810, Mil-Std-901, Mil-Std-167, Mil-Std-704, and more.
