Over 150 standard models are available with power ratings ranging from 600VA to 30kVA. Eight different input ranges, encompassing from 20VDC to 800VDC are standard, with a choice of 3x200VAC, 3x400VAC, or 3X480VAC outputs.
Housed in modular systems with interchangeable inverters, the IV Series features the ability to select either adjustable/programmable, fixed, or synchronized frequencies, allows for unsymmetrical load configurations, and has surge power capability.
Operating temperature is -20ºC to +75ºC, with -40ºC as an option. Additional options include further mechanical ruggedization for extreme environments and programming/monitoring functions. The use of industrial grade components, continuous short circuit protection, overload protection, and thermal shutdown with auto restart make the Schaefer IV Series a perfect choice for critical applications.
Mechanical and electrical modifications to standard modules are readily available upon request. In addition, Schaefer can design and manufacture fully custom solutions.
