The Cir-Kit Concepts' voltage regulator is a remarkable and innovative device which will greatly extend the life expectancy of any 12-volt bulb. The most significant restriction to long bulb life is the presence of excessive operating voltages. A relatively small increase in voltage may reduce a bulb's life by a factor of ten or more. Most commercial transformers start with a higher voltage at no load and typically provide the stated output voltage when supplying the rated output wattage. As would be experienced with any similar transformer, the Cir-Kit Concepts' transformers present voltages between 13 and 14 volts when lightly loaded. Only when loaded with ten or more bulbs can an acceptable output voltage be realized. To obtain this voltage when using 1 to 9 bulbs, a device such as the Cir-Kit Concepts' voltage regulator is recommended. This unique device automatically changes value as bulbs are added or subtracted from the system, thus maintaining a proper voltage across the connected bulbs. The automatic regulation feature allows this one simple device to take the place of several discrete resistors which would otherwise be required to obtain similar results. Equipped with terminal connectors; the lead-wire need not be cut as before. Detailed instructions included.

Not Required:

• When more than 10 bulbs are installed.
• For 14 or 16-volt bulbs.
• During construction when fewer than 10 bulbs may be temporarily in place.
• For CK1009B and CK1009F transformers.

These cords have been developed primarily for those instances where running power by wire may be more convenient than running it with tape; for example, where two miniature rooms are to be electrically connected together and work from one transformer. Another use might be between the top floor of a dollhouse and a removable roof or attic section. Headless brass pins are supplied with the CK1028 and CK1028-1 cords and are pounded into the tape runs to be joined. The plugs are then plugged into the pins to establish the interconnection. The connecting cords are 18" long and illustrated instructions are provided with each package.

The CK1028-5 Bridging Cord is used for interconnecting two tape mounted CK1007 Junction Splices (not included). Its use provides an extremely easy to install and low profile connection when completed. The connecting cords are 18" long and illustrated instructions are provided with each package.
