Secure power with redundancy

Healthcare facility power distribution systems have unique requirements regulated by numerous installation standards and guides such as IEC 60364-7-710, NF C 15-211, GB 16895.24, NFPA 99, HTM 06-01 and more…

The main facility is powered from redundant utility (mains grid) substations through high rating automatic transfer switching equipment (ATSE).

A backup source to the utility power is provided by means of a generator(s) and automatic bypass TSE to power critical and essential loads.

Less sensitive critical loads and UPS feeds are secured with open transition (I–0–II) ATSE located as close to the load as possible.

Static transfer switches (STS) and UPS are included downstream for highly sensitive critical loads providing no break and seamless transfer.

Periodic testing under load & maintenance is mandatory to ensure all systems are ready to operate free of any safety risks or potential issues.
