Model Explanation

• 51197066: Base part number for TDC3000 dedicated power supply PCB

• ‑200: High‑power revision (200W, redundant‑capable, for 10‑slot cabinets)

Technical Parameters

• Device Type: DCS system power supply (AC‑DC)

• Compatibility: Honeywell TDC3000 / TPS (controller & workstation cabinets)

• Input Voltage: 100–120/220–240 VAC, 50/60 Hz

• Output Voltage: +5 VDC, ±12 VDC (regulated)

• Output Power: 200 W max

• Efficiency: > 85% at full load

• Operating Temp: 0 °C to +55 °C

• Humidity: 5%–90%, non‑condensing

• Dimensions (W×H×D): Standard TDC3000 card (≈220 mm × 120 mm)

• Weight: Approx. 1.2 kg

• Certifications: CE, UL, CSA

Interface & Communication Configuration

• AC Input: IEC C13 connector (rear panel)

• DC Output: Backplane edge connector (power + GND)

• Status LEDs: AC OK, DC OK, Fault (card edge)

• Redundancy: Active‑active redundant operation (2 units)

Core Functions

• Isolated AC‑DC Conversion: Converts mains AC to regulated +5 V/±12 V for system cards

• Overvoltage/Overcurrent Protection: Shuts down safely under fault conditions

• Redundant Operation Support: Works in pairs for no‑break power

• Thermal Monitoring: Over‑temp protection with auto‑recovery

• Backplane Power Distribution: Supplies stable power to all slots in 10‑slot cabinet

Application Scope

• Honeywell TDC3000/TPS DCS (controller cabinets, GUS/US workstations)

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

• Critical control systems requiring high‑reliability power

• Replacement/upgrade of legacy TDC3000 power supply modules

Operation & Maintenance Instructions

• Install in dedicated power slot (usually slot 0) of TDC3000 cabinet

• Connect AC input before inserting into backplane; verify “AC OK” LED

• Check “DC OK” LED is lit; “Fault” LED off during normal operation

• Keep ambient temp < 55 °C; ensure cabinet ventilation

• Replace only with Honeywell‑certified 51197066‑200 power supplies
