    • A self contained multiple dimming channel package (20) includes a housing (22) with a main power circuit board (66) supported on its bottom wall and a control circuit board (68) extending laterally and vertically to baffle air flow through the housing (22). A cross flow cooling fan (162) forces air through an opening (154) in the control board (68) and across power switching modules (82) and toroidal chokes (84) mounted to the main board (66). Each power switching module (82) includes a heat sink (166) with fins (122) papallel to the air flow, and the chokes (84) are mounted in rows with their central openings (160) aligned with the air flow. The power switching modules (82) include circuits (124) attached to the heat sinks with terminals (134), 136, 138) releasably plugged into mating connectors (112) on the main board (66). Circuit breaker switches (42, 46) are snapped into place in the housing (22). The front corners of the housing (22) are provided with integral mounting bracket and handle members (198).
    • 自包含的多个调光通道封装(20)包括壳体(22),壳体(22)具有支撑在其底壁上的主电源电路板(66),以及控制电路板(68),横向和垂直延伸到通过壳体 22)。 横流冷却风扇(162)迫使空气通过控制板(68)中的开口(154)并且跨越安装到主板(66)的功率切换模块(82)和环形扼流圈(84)。 每个功率切换模块(82)包括具有与空气流平行的翅片(122)的散热器(166),并且扼流圈(84)以其中心开口(160)与气流对准的方式安装成行。 电源开关模块(82)包括附接到散热器的电路(124),端子(134),136,138可释放地插入到主板(66)上的配合连接器(112)中。 断路器开关(42,46)被卡扣在壳体(22)中的适当位置。 壳体(22)的前角设置有一体的安装支架和手柄构件(198)。
