The IPS-ICU Series 710 modular is a highly specialized distribution cabinet designed for the secure power supply of group 2 medical locations, such as operating rooms and intensive care units. The system ensures the continuous supply of vital medical equipment, even in the event of an initial fault (e.g., insulation fault or short contact through body contact) or a failure of the general power supply.

System Architecture and Main Components

• Separate Transformer Boxes: The IPS isolating transformer (up to 8 kVA in Germany) is housed in a separate transformer box, which can be mounted either directly on top of the standing cabinet or remotely from the wall cabinet.

• Precise Switchover Control: In the event of a voltage drop in the preferred feeder (line 1), the system switches over to the redundant feeder (line 2) in less than 0.5 seconds (class 0.5).

• Continuous Monitoring: The integrated modules (UEI-710-V.5, ILT-710-V.5, or ILT-710-V.4) permanently monitor the insulation resistance of the IT system, as well as the load current and temperature of the isolating transformer.

• Optional Insulation Fault Detection: With the optional IFS-710-W6 device and the integrated test signal generator, faulty circuits can be located automatically during operation (up to 96 channels).

• Digital Networking: All operating and fault messages are transmitted via the CAN bus to external peripheral devices, such as the operating and annunciator terminals of the BMTI series (e.g., BMTI 1, BMTI 2, BMTI 5) or the building services control system.

Modular Design and Scalability Thanks to its modular structure, the system offers flexibility for a wide variety of hospital infrastructures and can be adapted to specific power requirements:

• Expansion Stages: Available as Single IPS (S-IPS, 300 mm width), Double IPS (D-IPS, 600 mm width), and Triple IPS (T-IPS, 800 mm width).

• Cabinet Heights: The distribution cabinets are available in standard heights of 1250 mm and 1400 mm (with a depth of 350 mm).

• Output Circuits: Depending on the expansion stage and design (with bypass switch or bypass terminal), between 6 and 54 output circuits can be implemented.

• Bypass Function (Optional): Enables bridging circuits for maintenance work on the change-over and monitoring modules without interrupting the power supply to the connected loads.

International Safety Standards The system complies with strict international standards for medical power supply, including IEC 60364-7-710 and DIN VDE 0100-710, and achieves a Safety Integrity Level of SIL 2 (IEC 61508). This optimally qualifies the IPS-ICU Series 710 modular for international healthcare and infrastructure projects that require maximum reliability and precise technical documentation.
