HR3002PE Schneider HR3000 Guest Room Expansion Module Dedicated Power Supply AC 220V Input Power Unit

The HR3002PE serves as the dedicated power supply for expansion modules within the HR3000 guest room control system. This unit addresses the physical limitation where a single power supply cannot adequately support multiple modules in larger configurations. In suites, rooms with extensive lighting groups, or installations requiring multiple function modules for dimming and curtain control, the bus load exceeds the capacity of a single unit.

Rather than oversizing the main supply for every room, this design provides a secondary supply that operates locally with expansion modules. Featuring single-phase AC 220V input with wide tolerance and 12V DC module bus output, this separation enhances system availability by confining expansion-side faults to the specific modules they serve.

Determining the need for a secondary supply should be calculated during module scheduling rather than discovered during commissioning. Each function module's worst-case current should be documented before panel layout.

Proper clearance, ventilation within the enclosure, and connection to a protected circuit are essential for optimal service life and performance.

• Hotel Suites: Multiple lighting groups, curtain control, and additional dimming channels exceed single supply capacity
• Large Standard Rooms: Enhanced lighting schemes in resort properties requiring additional power
• Executive Floors: Advanced room control systems beyond minimum specifications
• Serviced Apartments: Multiple habitable spaces per unit, each with dedicated function modules
• Refurbishment Projects: Extending existing rooms with dimming or curtain control not originally sized for
• Maintenance: Essential spare part for maintenance departments
