IMPROVED LOW VOLTAGE POWER SUPPLY AND DISTRIBUTION CENTER

摘要

A low voltage power supply and distribution center comprises a housing (12) having three internal compartments including: a high voltage compartment (17), a low voltage distribution compartment (19), and a transformer compartment (21). The housing (12) is designed for surface or recessed mounting on or in a wall or ceiling. For recessed mounting, with the housing (12) surrounded with 20 cm (8 inches) of insulation, the maximum surface temperature of the housing is less than 90 DEG C. The three compartments (17, 19, 21) are formed by a removable power tray (15) having a toroidal transformer (132) mounted thereon. The low voltage compartment (19) comprises a fuse panel (150) for mounting a plurality of plug-in fuses (153) from which the low voltage power is distributed. The high voltage compartment (17) comprises a switch or a dimmer (131) in a high voltage line between the transformer (132) and the incoming high voltage line, or the dimmer or switch may be remotely installed on a wall. An optional choke (133) may be provided in the high voltage compartment (17) for use with a dimmer. Additionally, a primary current protection circuit (135) may be provided to add additional protection for over current conditions. A mounting cover (54) is provided to cover the housing (12) to provide a more refined appearance, and vent holes (60) are provided in the cover (54) in the area of the transformer (132). The low voltage power supply and distribution center may be used for a National Electrical Code (NEC) class 1 and/or a class 2 wiring installation.
