i-STS Model B1 Source Transfer Switch Solid State Rackmount 16amp
(£2,274.00 inc VAT)
The i-STS15B1s1P2 from Critical Power Supplies Model B1 is a 2 pole, single phase 1RU 19" rack mount point of distribution static transfer switch. With up to 15A of switching capacity, the B1 is perfect for any small to medium rack-based installation.
The Model B1 is the worlds smallest and fully functioned rack mounted Static Transfer Switch (STS) which features the reliability and high fault capacity of solid
state thyristor switching as opposed to relay based Transfer Switches that are usually offered in this physical size.
All B1s’ come with discrete remote Voltage free Contacts and remote Controls Inputs, Modbus and LAN WEB Server and SNMP built in. Combine this with bi-colour LED mimic to provide instant recognition of STS state and a backlit LCD information display to provide real-time variables, status and event history.
