Hospital construction projects have strict requirements for electrical safety and stability, as they relate to medical equipment operation and patient safety. Low-voltage control cabinets, the core of the hospital’s low-voltage power distribution system, undertake power distribution, control, protection and monitoring tasks. This article briefly introduces their common types, functions, and key Schneider SpaceLogic control accessories (with specific models) for hospital construction reference.

Low-voltage control cabinets are widely used in hospital functional areas (outpatient buildings, operating rooms, imaging centers, etc.). Different areas have different requirements for electrical load and protection, so matching cabinet types are needed. The core requirements are high stability, strong anti-interference, easy maintenance, and compliance with medical standards to ensure continuous operation of medical equipment and daily electrical systems.

According to hospital functional needs, low-voltage control cabinets are mainly divided into 5 types:

Installed in building power distribution rooms, it distributes 380V/220V power to lighting, sockets, medical equipment and ventilation systems. It realizes power on-off control and protects circuits from overcurrent, short circuit and undervoltage faults, ensuring stable power supply.

Designed for high-precision medical equipment (CT, MRI, ICU ventilators), it provides stable, clean power to avoid voltage fluctuations and electromagnetic interference. It is equipped with backup power interfaces to ensure normal operation during sudden power outages.

Controls central air conditioning units, ventilation fans and air purifiers, adjusting fan speed, air valve opening and monitoring temperature/humidity to meet medical clean standards and save energy.

Controls lighting on-off, dimming and switching in different areas, realizing centralized and intelligent management (e.g., automatic day-night switching) to improve convenience and save energy.

Controls fire pumps, fire fans and emergency lighting. It starts fire equipment quickly in case of fire, cuts off non-fire power, and monitors equipment status to ensure fire system standby.

Schneider SpaceLogic series, relying on EcoStruxure™ open architecture, is widely used in hospital control cabinets for its stability and intelligence. Key accessories with models, scenarios and functions are as follows:

• MP-C1000-0: For central air conditioning/clean area cabinets, supports BACnet/IP, UL 864 compliance, suitable for operating room/ICU temperature/fresh air adjustment.
• RP-C200-0: For ward FCU and lighting cabinets, integrates 8 I/Os, supports PIR induction for energy-saving lighting control.
• AS-P100: Central monitoring room server, aggregates data, realizes centralized visualization and multi-system linkage.

• SXWUI160110001: Universal I/O module, collects digital/analog signals for medical equipment and power distribution cabinets, easy on-site expansion.
• SXWDOA12010001: Digital output module, controls fire equipment and lighting, complies with UL 864/916 standards.

• THT-1000: Temperature/humidity sensor for operating rooms/ICUs, supports automatic environment adjustment.
• CO2-2000: CO₂ sensor for crowded areas, links with ventilation systems.
• EVA-500: Electric valve actuator for air conditioning/water treatment cabinets, corrosion-resistant.

• HMI-7000: Glass touch screen, displays equipment status and supports parameter modification, compatible with EBO system.
• SE8350-0: Room controller for wards/outpatient clinics, optimizes HVAC operation and reduces energy consumption.

• RS485-ISO: RS-485 adapter, solves protocol compatibility between new and old equipment.
• MTN680329: KNX/IP gateway, realizes Ethernet connection, supports encrypted transmission.

1. Comply with medical standards (e.g., GB 16895.2-2018) for electrical safety.
2. Prioritize anti-interference accessories and reasonable cabinet shielding.
3. Adopt redundancy design and high-reliability SpaceLogic accessories.
4. Choose easy-to-maintain cabinets and standardized Schneider accessories.

Low-voltage control cabinets are vital for hospital operation and patient safety. Selecting appropriate cabinets and high-quality Schneider SpaceLogic accessories improves the stability and intelligence of the power distribution system. Scientific configuration based on area needs meets medical industry high standards.
