The manual for the Drake CPS-1 Power Supply provides detailed instructions for setting up and operating the unit, including how to connect it to compatible models like the SCC-1 and SC-2 or SC-6, and emphasizes the use of an On-Off switch and a Cinch-Jones plug for operation. It also covers troubleshooting aspects such as overload protection through a fuse and offers guidance on installation for mechanical stability and minimizing interference.
Manual Overview
The Drake CPS-1 power supply is a solid-state unit designed to power specific Drake models, including the SCC-1 and either the SC-2 or SC-6. It features a full-wave bridge rectifier circuit with silicon diodes and a 1000 mfd electrolytic capacitor for filtering. The unit operates from a 120 V, 50/60 Hz source and includes an On-Off switch for controlling power. Overload protection is provided by a 2/10 ampere fuse located on the power supply’s printed circuit board.
For troubleshooting, ensure all connections are secure and the fuse is intact. If the unit fails to power on, check the fuse and replace if necessary. Calibration and adjustments are not detailed in the manual, but the power supply should deliver +21 volts DC open circuit and +17.5 volts DC at 50 mA. The maximum current output is 100 mA. For installation, connect the CPS-1 to the SCC-1 and either the SC-2 or SC-6, using the provided metal strap for mechanical stability. For further integration into the converter console CC-1, refer to the CC-1 manual.

Drake CPS-1 Instruction Manual Overview
The Drake CPS-1 is a precision communication power supply designed to provide stable and reliable power for amateur radio and other electronic equipment. Known for its robust construction and efficient performance, the CPS-1 ensures consistent voltage regulation, making it an essential component for maintaining optimal operation of sensitive radio devices.
Main Features and Specifications
- Output Voltage: Adjustable DC output ranging from 13.8V to 15V
- Maximum Current: Up to 25 Amps continuous output
- Built-in Overload and Short Circuit Protection
- Heavy-duty transformer for stable power delivery
- Cooling fan for thermal management during extended use
- Compact and durable metal chassis design
- Analog meters for voltage and current monitoring
Basic Usage and Operation Tips
Before powering your radio equipment, ensure the CPS-1 is connected to a proper AC power source with the correct voltage rating. Adjust the output voltage knob to match your device’s requirements, typically around 13.8V for most amateur radios. Monitor the built-in meters to verify stable voltage and current during operation. Avoid operating the power supply beyond its rated current to prevent overheating or damage. Allow the cooling fan to function unobstructed to maintain optimal temperature.
Troubleshooting and Maintenance
If the power supply fails to output voltage, first check the AC input and fuse condition. Inspect all connections for corrosion or looseness. In case of overheating, ensure the cooling fan is operational and vents are clear of dust or obstructions. Regularly clean the exterior and ventilation openings with compressed air to prevent dust buildup. For persistent issues, consult the detailed schematics in this manual or contact a qualified technician for repair.
Safety Reminder
Always disconnect the CPS-1 from the AC mains before performing any maintenance or inspection. Avoid contact with internal components while the unit is powered to prevent electric shock. Use the power supply only within its specified ratings and never operate it in wet or damp environments. Proper grounding is essential to ensure safe operation and protect both the equipment and the user.
