Description

Static Power iSTS-B1

Single Phase, 2 Pole 1U Rack Mounted Static Transfer Switch

With up to 32A of switching capacity, the iSTS B1 is the perfect Static Transfer Switch – STS – for any small to medium rack-based installation that requires advanced supervisory monitoring and control. This STS features as standard a hot-swappable power module and integrated maintenance bypass enabling continuous power during servicing.

Fully configurable, the LED mimic and graphic OLED display interface enables easy access to user settings and operating variables. All events are recorded in real-time with time synchronisation available via NTP. Remote connectivity is achieved via Ethernet and 20-way header.
