Information About S54430-C27-A1
The S54430-C27-A1 is part of Siemens’ Desigo Fire Safety Modular family, engineered as an auxiliary high-current supply that integrates seamlessly with PSC-12M units. Built with a universal AC input range of 120–240VAC, the PSX-12M requires no special configuration and includes a switch-mode converter with power factor correction to improve efficiency. Its addressable, microprocessor-controlled design communicates system status, loading conditions, and fault alerts to the Operator Interface (FCM2041-U2). With diagnostic LEDs, dual output circuits, and backplane bus connectivity, this power extender provides a dependable and scalable solution for large fire alarm installations.
Key Features:
- Auxiliary Power Expansion: Provides 12A of regulated 24VDC power for Desigo Modular systems.
- Dual Output Terminals: One 4A power-limited output and one 12A non-limited output (combined max 12A).
- Universal AC Input: Accepts 120–240VAC at 50/60Hz with no special setup.
- Microprocessor Control: Reports module status, ground faults, and load data to the Operator Interface.
- System Integration: Connects via 60-pin power/data bus for seamless communication with system modules.
- Diagnostic LEDs: Provides visual indication of power status, network faults, and output failures.
- Modular Mounting: Installs in one of four module spaces or onto CAB-MP mounting plates in CAB1, CAB2, or CAB3 enclosures.
- Scalable Design: Supports connection of up to three PSX-12M units per PSC-12M for expanded capacity.
The S54430-C27-A1 delivers the reliability and precision required for scalable power distribution in advanced fire safety systems.
