6130-17-005-4123 6130170054123 170054123 is 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.

5905-00-005-4123 5905000054123 000054123 is a resistor in which a sliding or rolling contact moves over an exposed area of the resistive element to change the ohmic value of the output. the functional tolerance (linearity), if given, of the output is greater than plus or minus 1 percent on linear outputs. specified outputs such as sine, cosine, tangent, etc., shall be considered to be precision. for items having manually positioned taps designed to be set and fixed prior to use, see resistor, adjustable. for items with step by step variation, see rheostat and resistor, step by step. for tandem-mounted items designed to function together as an attenuator (and rated accordingly), see attenuator, variable. excludes resistor (1), variable, wire wound, nonprecision; resistor (1), variable, nonwire wound precision; and resistor (1), variable, wire wound, precision.

6220-20-005-4123 6220200054123 200054123 is a rigid or group of rigid item(s) designed to position and/or restrain the movement of one or more light(s) and/or light units. may include mounting holes, screw threads, clips, or other fastening devices and electrical contacts.

6110-33-005-4123 6110330054123 330054123 is an enclosure which includes mounts, and protects such items as switches, circuit breakers, jacks, fuseholders, connectors, terminals and/or terminal boards, resistors, capacitors, transformers, and the like. it is primarily designed to distribute electrical power from one or more primary power source(s) such as generator(s) and battery(ies) to one or more electrical and/or electronic item(s). it may include a cover or door. for enclosures which include only circuit breakers, switches, jacks, fuseholders, terminals and/or terminal boards, see circuit breaker box; switch box; jack box; fuse box and terminal box. for enclosure primarily designed to interconnect two or more electrical and/or electronic items, except primary power source(s) see interconnecting box. for empty boxes which are designed to mount, but do not include electrical devices such as switches, jacks, fuseholders, terminals and/or terminal boards, see junction box. see also interconnecting cabinet; control (as modified); panel (1) (as modified); relay assembly; panel, power distribution; switchboard (as modified) and panel, fuse. excludes connector-switch.
