Bender, which has over 70 years’ experience in the design and manufacture of electrical safety systems, has launched the ATICS changeover system in the UK.

Developed harnessing the experience gained during its involvement in the preparation of HTM06-01, Bender says ATICS ‘marks a watershed’ in critical power system design.

For category 4 and 5 medical locations such as operating theatres and intensive care units, a secondary supply must be available within 0.5 seconds should the primary supply fail. Fully monitored and with wraparound bypass facilities, integral insulation/transformer monitoring, and a ‘unique’ rotary cam arrangement for increased reliability, the compact, modular system offers enhanced levels of resilience said to be unique. The integral bypass switch enables testing or replacement during service works without interrupting the power supply – considerably enhancing safety, particularly in busy areas operating ‘24/7’, such as intensive care and neonatal units.

The ATICS auto-changeover system complies fully with all relevant standards, and is independently certified by an independent technical inspection authority, TUV SUD, in accordance with EN61508 SIL 2 and DIN VDE 0100-710.

To achieve SIL 2 compliance and deliver the highest level of dependability, Bender’s R&D department developed complete redundancy throughout the design, using dual microcontrollers and failsafe software platforms. The work took specialist engineers two years to complete.

Available in single or three-phase versions, ATICS can be retrofitted within single-feed IPS panels to quickly achieve HTM06-01 compliance. Bender believes ATICS is also compatible with UPS systems and the COM460 smartphone gateway. The company says the system offers the market’s ‘highest level of protection and compliance’.
