Honeywell · Power Supplies & Transformers

Description  The Honeywell MPS-24A is a regulated power supply card designed to support fire alarm control panels such as AM2020, AFP1010, and XP Transponder systems. It provides 3.0 amps of filtered 24 VDC output power and includes a battery charging circuit for standby operation.     Technical Specifications  Condition New/Never Used Surplus Brand Honeywell Category Power Supplies Part Number MPS-24A Subcategory Power Supply Input Voltage 120 V AC (50/60 Hz) Output Voltage Regulated 24 VDC Output Current 3.0 A filtered (6.0 A max shared with internal) Battery Charging Capacity 9 AH to 55 AH Battery Type 24 V float-charge lead acid LED Indicators AC Fail, Battery, Ground Fault Mounting Panel mount in CAB-A3/A4, B3/B4, C3/C4, D3/D4 Certification UL, FM, CSFM, MEA, CCC, Lloyd’s, USCG, IRAM Weight 11.57 lbs       Information About MPS-24A The MPS-24A functions as the main power source for multiple Honeywell fire control platforms, delivering power to internal system electronics and up to 3.0 A for external notification appliance circuits. It accepts 120 V input (50/60 Hz) and includes regulated 24 VDC output with overcurrent protection. The unit features status LEDs for AC loss, ground fault, and battery conditions. It can charge up to 55 AH batteries, supports dual-rate charging, and integrates with compatible Honeywell enclosures (e.g., CAB-A3/A4, B3/B4). A high-efficiency DC-DC converter is included for internal +5 V operation, and filtered +24 VDC outputs are designed to power horns, strobes, or release solenoids. Key Features: 3.0 Amp Regulated Output: Provides filtered 24 VDC for internal and external fire system components. Battery Charging Support: Charges batteries from 9 AH to 55 AH with dual-rate and float charging modes. AC Input 120 V (50/60 Hz): Primary power input with optional 220 V version available. LED Status Indicators: LEDs for AC power fail, battery fail, and ground fault status. Circuit Protection: Includes circuit breaker and PTC resettable fuses for short-circuit and overload protection. DC-DC Converter for +5 V: Powers control panel logic modules without additional converters. Panel Mount Integration: Installs in lower-left section of CAB-A/B/C series enclosures. Notification Appliance Compatibility: Supports any listed 24 VDC notification device. True Supervision: Built-in battery and fault supervision for critical safety applications. Agency Approved: UL, FM, CSFM, MEA, CCC, Lloyd’s Register, USCG, and more. The MPS-24A ensures stable and fault-monitored power delivery to both internal controls and external signaling circuits in fire alarm systems.
