Description
The Honeywell 51195066-100 is a five-slot chassis power supply associated with the Honeywell TDC 3000 control system. It is designed to provide multiple DC output rails for chassis-mounted control and interface electronics.
The unit accepts 120/240 VAC input at 47–63 Hz and provides four DC output rails: +5 VDC, +12 VDC, -12 VDC, and +24 VDC. The published ratings are 30 A for +5 VDC, 8 A for +12 VDC, 1 A for -12 VDC, and 1 A for +24 VDC.

🔧 Key Features
• Designed for five-slot Honeywell chassis applications
• Multiple DC output rails for system electronics
• 120/240 VAC input capability
• 47–63 Hz operating frequency
• Supports +5 VDC, +12 VDC, -12 VDC and +24 VDC outputs
• Suitable for legacy Honeywell control-system maintenance and spare-parts requirements
• Useful as a replacement power-supply assembly when the installed system requires the same part number
⚠️ Installation Notes
Before installation, verify the chassis configuration and the exact power-supply part number. Pay particular attention to the input voltage selection, output ratings, connector arrangement, and chassis requirements.
Because this is an older TDC 3000 component, buyers should also compare the nameplate and revision information on the actual unit with the existing installation before replacement.
❓ Common Questions & Answers
Q1: What system is the 51195066-100 used with?
A: It is identified as a five-slot chassis power supply associated with Honeywell TDC 3000 systems.
Q2: What is the input voltage?
A: The unit supports 120 VAC and 240 VAC input, with published input currents of 6.0 A at 120 VAC and 3.75 A at 240 VAC.
Q3: What are the DC outputs?
A: The four published output rails are +5 VDC, +12 VDC, -12 VDC and +24 VDC.
Q4: What is the maximum +5 VDC output rating?
A: The published rating is 30 A at +5 VDC.
Q5: Is 51195066-100 the same as 51195066100?
A: Yes. 51195066100 is commonly used as the same part number without the hyphen.
Q6: Is this a standalone 24 VDC power supply?
A: No. It is a multi-output chassis power supply. Its output configuration includes four DC rails rather than only a 24 VDC output.
Q7: What should I check before ordering?
A: Confirm the part number, input configuration, connector arrangement, chassis type, output ratings, and revision on your existing unit.
Q8: Is the 51195066-100 still a current Honeywell product?
A: Available product records identify this part as discontinued, so it is primarily relevant to legacy-system maintenance and spare-parts replacement.

🛠️ Inspection Before Shipment
For a New Surplus unit, recommended inspection includes visual condition, nameplate/part-number verification, connector inspection, input-side inspection, output-voltage testing, and confirmation of the four DC output rails where test equipment and the appropriate test procedure are available.
Note: Some online listings give conflicting dimensions and weights for this assembly, so I would avoid publishing an exact dimensional figure unless it has been verified from the physical unit or the original Honeywell documentation.
