Honeywell 51198947-100
Product Name: HPM Power Supply (AC/DC Output Power Supply)
Overview:
The Honeywell 51198947-100 is an HPM power supply unit designed for Honeywell UCN (PM, APM, or HPM) device cabinets. It is the “silver” upgraded version replacing the older “black” power supplies, providing multi-channel DC outputs and incorporating a battery charging circuit for 48 VDC battery input.
Detailed content
Technical Specifications:
- Product Type: HPM Power Supply (DCS parts) – AC input, AC/DC output
- Input Voltage: 85 to 264 VAC or 48 VDC (battery)
- Input Frequency: 50/60 Hz
- Output Voltage:
- 25.25 VDC (at 10 A load) when powered by AC line
- 24.25 VDC when powered by 48 V battery
- 6 VAC nominal line-frequency output (35 mA rated load) for line-frequency synchronization (e.g., for LLAI IOPs to reduce AC noise)
- Rated Power: 550 W
- Output Current: 20 A (24 VDC output)
- Redundancy: Designed to support redundant configuration using two or more paralleled units
- Operating Temperature: -20°C to +55°C at full load; linearly derated above 55°C by 0.5 A/°C up to max +65°C
- Shipping Weight: 5 kg
- Compliances: CE, all applicable EEC directives
- Compatible Systems: Honeywell TDC 3000, Experion PKS (PM, APM, HPM systems)
Features:
- Built-in rechargeable battery charging circuit for 48 VDC battery input.
- Over-current and short-circuit protection.
- Industrial-grade rugged design.
- Paralleled outputs supported for higher current or redundancy.
- Silver-version upgrade replacing legacy black power supplies.
Applications:
- Power source for Honeywell UCN cabinets (PM, APM, HPM).
- Deployed in TDC 3000 and Experion PKS control cabinets with redundant configuration for high availability.
- Mission-critical process automation in refineries, petrochemical, power plants.
Installation & Notes:
- Supports redundant configuration by paralleling two or more units.
- When using 48 VDC battery input, the built-in charger maintains battery health.
- Above 55°C ambient, output current derates by 0.5 A per degree Celsius.
- Ensure proper ventilation in the cabinet; shipping weight is 5 kg so secure mounting is required.
