Schaefer Intros Inverter Line
DC/AC inverter.
Ashland, MA — Schaefer, Inc. is introducing the IV Series of DC/AC inverters. The inverter design synchronizes three individual switch mode inverters and three output transformers, for a symmetrical 3-phase output. The transformers provide input/output isolation, while transforming the voltages to user required outputs. Over 150 standard models are available with power ratings ranging from 600VA to 30kVA.

Eight different input ranges from 20VDC to 800VDC are standard, with a choice of 3 x 200VAC, 3 x 400VAC, or 3 X 480VAC outputs. Housed in modular systems with interchangeable inverters, the IV Series has the ability to select either adjustable/programmable, fixed, or synchronized frequencies, allowing for unsymmetrical load configurations. The inverters also have surge power capability. Operating temperature is -20 to +75°C, with -40°C as an option. Additional options include further mechanical ruggedization for extreme environments and programming/monitoring functions. The inverters are made with industrial grade components, and provide continuous short circuit protection, overload protection, and thermal shutdown with auto restart.

Mechanical and electrical modifications to standard modules are readily available upon request. In addition, the company can design and manufacture fully custom solutions.
