Product Overview
Abbott Transistor Laboratories model CC12D1.0 (part number 16897) is an encapsulated, baseplate-cooled DC-to-DC converter built for industrial and aerospace electronic assemblies. Operating from a nominal 24 to 30 VDC input, the module produces balanced positive and negative 12 VDC rails rated at 1.0 amp each across a shared common terminal. A sealed top-panel potentiometer provides output voltage trimming, while the machined aluminum baseplate secures directly to an external heatsink or chassis wall to maintain operating temperatures under 212°F.
Key Features
- Dual tracking output delivering +12 VDC and -12 VDC at 1.0 A continuous each
- Input range accepting 24 to 30 VDC with 2.5 A maximum fuse rating
- Encapsulated chassis-mount enclosure with bare aluminum conduction baseplate
- Four corner threaded mounting holes for direct thermal interface to chassis or heatsink
- Hermetic top terminal header with individual pins for input and dual outputs
- Top-accessible output voltage adjustment potentiometer with knurled protective cap
- Integrated base thermal indicator calibrated for 220°F / 104°C threshold monitoring
Applications
- Powering analog op-amp stages and signal conditioning circuits requiring balanced split ±12V rails from a 24V bus
- Bench testing avionics, legacy telecommunications gear, and mobile equipment running on 28 VDC prime power
- Replacing obsolete encapsulated DC-DC converters in industrial control chassis and test sets
- Supplying low-noise dual-rail power in custom maker audio preamps and analog synthesizer projects
Frequently Asked Questions
What are the terminal pin assignments on the top header?
Pin 1 is +Input, Pin 2 is -Input, Pin 3 is +Output (+12 VDC), Pin 4 is Common Output, and Pin 5 is -Output (-12 VDC).
Does this converter require an external heatsink?
Yes. The baseplate must be mounted to a heatsink or substantial metal chassis surface to prevent the base temperature from exceeding 212°F during operation.
What testing has been done, and what is included with this unit?
Visual inspection only; function testing has not been performed. The module includes its knurled potentiometer cover and attached wire pigtails.
Built back when high-reliability power meant a solid potted cube that could take a beating on a 28-volt military rail. Bolt it down to a thick plate, hook up your input, and let those clean dual rails go back to work.
