i-STS Model C1 Source Transfer Switch Solid State Wall Mount 32amp
(£4,500.00 inc VAT)
The * i-STS32C1s1P2 Model C1 Solid State Source Transfer Switch* from critical Power Supplies is our single phase wall mounted Static Transfer Switch (STS). Designed to provide uninterrupted power in industrial / commercial sites where Point of Distribution type Static Transfer Switches are inappropriate because of the load types and fault levels and where the STS is to be located.
Your equipment is automatically protected switching between two independent power sources upon detection of a problem. To avoid the dangers of paralleling power sources, all switching is break before-make and ensures no disruption to the operation of your connected equipment.
With limited install infrastructure this unit offers zero footprint and industries smallest physical size. For wall or within switchboard mounting. Only 280 mm depth (Size 400 wide x 400 high, (mm).
