The NPS-I and NPS-II switches allow instantaneous transfer of load between two power sources. It can be used to ensure complete redundancy of power supply up to the last piece of wire. It useful in many applications where redundant power supply is available, either from two UPS systems or one UPS and bypass source.
Uses Power semiconductors as Switching Element
Simple and rugged design
User-friendly display and control
MODBUS RS 232/484 Interface (optional)
Potential free contacts (optional)
Designed for High Nines Availability
Break- Before - Make switching eliminates any possibility of connecting the two independent power sources together, even under fault conditions.
Diagnostics and transfer tests detect any potential switch failures before the problem becomes critical.
Network Power Switch transfer time of six milliseconds is invisible to sensitive electronic equipment. (As per IEEE Standard 446 susceptibility curve for IT component)
Automatic transfer protects the critical load as soon as a problem is detected on the power source by switching to the alternative supply.
Manual transfer allows power sources to be switched whenever required for scheduled source shutdowns or maintenance.
