PWR 30
Modular Switched Mode Rectifier System PWR 30
The PWR 30 is a compact, state-of-the-art rectifier system designed for today’s
space restricted communications applications. PWR 30 rectifier systems are designed to
provide the ultimate in flexibility and modularity. Each rectifier system PWR 30 can
accommodate up to three power modules APC TWF0500 9A/54,5VDC in only 4 rack units
of space. In addition to allowing hot plug-in modules, the PWR 30 provides front access
for ease of installation, maintenance and upgrading. The available output voltages are
ideal for the telecommunication and data communication markets.
