Schaefer Inc.

8000W Power Converter

Schaefer, Inc. introduces the CW5300 Series of water
cooled, 8000 Watt DC/DC and AC/DC converter modules. The Series'
compact, yet robust, design yields an extremely high power density,
offering a space-saving solution for even the most extreme
environments in industries such as railway controls/communications
equipment (onboard and trackside), military, alternative energy,
transportation, and process control systems.

The CW5300 Series is available in 5 standard DC input voltage ranges
from 80-800VDC, as well as 3-phase AC input voltages including 3 x
200VAC, 3 x 400VAC, and 3 x 480VAC. Single outputs are available in
9 standard ranges spanning 14-400VDC. All outputs are adjustable and
fully regulated to 0.2% or better (load) and 0.1% (line).

All modules in the CW5500 Series have remote sensing (up to 150VDC
output), overvoltage protection, and current limit protection.
Efficiencies are up to 95%. Operating temperature is -20C to +75C,
with -40C to +75C as an option.

The units are packaged in a space saving 5U x 19" x 600mm (HxWxD) rack
module and incorporate terminal / bolt / bar connection points.
Available options include decoupling diodes for parallel / redundant
operation, "ruggedization", inhibit, Power Fail / DC-OK alarms, system
reset, active current sharing, and programming.

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