Static Transfer Switch

3 Phase Static Transfer Switch

Product description:
INQUIRY

3 Phases 63~400A

The STS product is designed with two independent power inlets to supply power to the load from a primary power source.
Should primary power source fail, the secondary will automatically back up the connected equipment without any interruption.
The transfer time from one line to another is seamless to the connected equipment. After switching to a secondary power source, the STS can also switch power back to the primary input when power to the primary input is restored.
Powered by two separately independent power sources

Dual power supply for redundancy

Provides seamless power switch for IT equipment

Transfer time:≤6 ms

Input Source -A is P riority
