Network Power Switch (NPS)/
Stastic Tranasfer Switch
A Network Power Switch (NPS) or Static Transfer Switch (STS) is a high-speed switching device that ensures seamless power redundancy for critical electrical loads. It automatically transfers the load between two independent power sources in case of a failure, ensuring continuous uptime and reliability in data centers, industrial automation, telecom, and UPS systems.
Benefits
- Instantly switches to an alternate power source in case of failure.
- Fast switching (typically < 4ms) ensures seamless operation.
- Reduces downtime by providing automatic power redundancy.
- Distributes power evenly between sources to improve efficiency.
- Allows real-time status updates via web interface or SNMP.
- Prevents damage by detecting overcurrent, voltage fluctuations, and short circuits.
