• 48V Battery Charging: Integrated charger for backup systems

• Wide‑Range AC Input: Global mains compatibility

• Enhanced Reliability: Revision B upgrades for harsh environments

• Redundant Operation: Supports parallel connection for redundancy

Application Scope

• Honeywell TDC3000/TPS DCS (UCN PM/APM/HPM cabinets)

• Process industries: power, oil & gas, refining, chemical

• Critical control rooms with 24/7 battery‑backed operation

• Direct replacement for 51198947-100 or 51109684-100

Operation & Maintenance Instructions

• Mount in clean, ventilated cabinet (ambient <55°C)

• Connect IEC C13 to AC mains; DC output to UCN backplane

• Connect 48V battery to charge port for backup

• Verify “Power”/“Output” LEDs on; “Fault” LED off

• Use only Honeywell‑certified 51198947-100B replacements
