Special Features:

Functional description a pulse width modulated dc to dc converter that provided regulated multiple output power; converts transforms an unregulated 28 vdc to a regulated adjustable dc output via a remote control potentiometer or voltage for voltage controlled models; primarily designed to control the light intensity of incandescent bulbs in lighting systems; input voltage 28 vdc ; output voltage adjustable with external 5k ohm, 1/2 w rheostat or voltage 0-5 v dc; regulation 2 pct for line, 2 pct load and 2.5 pct temperature; common mode isolation 40 db; output ripple 25mv p-p or less; protection overvoltage output voltage is limited to aproximately 125 pct of rating even though remote control rheostat opens or internal failure occurs; output current 11 adc total; efficiency 84

Properties:

A component which converts available alternating current or direct current electrical power into a form required to operate another component or set. The item may consist of a combination of an invertor, vibrator; vibrator, interrupter; vibrator, self-rectifying; invertor, power, static; with a transformer and rectifier(s) employing electron tubes, semiconductor diode or metallic (dry disc) type components, or the synchronized secondary contact(s) of a vibrator, self-rectifying; or may consist of electron tubes, semiconductor diode or metallic (dry disc) type rectifiers and capacitors in transformerless (alternating current-direct current type) circuits which may be of the voltage-multiplier type. The item may incorporate a filter, direct current power and provisions for regulation of input and/or output voltage. The item may have special input, output, control or other facilities for applications in specialized environments such as medical, dental or other operations. Excludes battery chargers and rotating machinery types of items, such as motor generators and dynamotors.
