System and method for thermal protection for a universal load control cabinet

摘要

A universal load control module may include a power supply that operates over a wide voltage range, a microcontroller, and one or more functional control blocks. A functional control block may include a dimmer circuit for controlling a lighting load that provides reverse phase cut mode dimming, forward phase cut mode dimming, and hybrid phase cut mode dimming, as well as thermal protection. One or more universal control modules may be housed in a cabinet that include a cabinet control module. The cabinet may include additional thermal protection measures.

主权项

1. A lighting control system, comprising:
a plurality of load control modules, wherein each load control module controls a load and includes a power supply that operates over a wide voltage range, and at least one load control module includes a dimmer circuit that includes a microcontroller and circuitry to control a phase control signal; a thermal shelf mounted between two vertically adjacent load control modules, the thermal shelf having one or more inclined surfaces to disrupt heat flow from a lower vertically adjacent load control module to a higher vertically adjacent load control module; and a plurality of vents located in a panel of a cabinet, wherein the vents are located proximate to the load control modules.
