  • Watt trimming controller for a heated glass temperature-controlled storage device
    Patent number: 10080447
    Abstract: A controller for trimming power used by a heated glass temperature-controlled storage device comprising a frame and a door, the door comprising a door rail and a glass pane, wherein the glass pane includes a glass heater circuit, the controller comprising a variable impedance; a first impedance; a low pass filter; a diode for alternating current (DIAC); and a triode for alternating current (TRIAC), wherein the controller is configured to adjust voltage from the AC power input to a first voltage; filter the first voltage; generate a gate current when the DIAC is on; generate a glass current when the TRIAC is on; and provide the glass current to the glass heater circuit when the TRIAC is on, wherein the variable impedance is adjusted so power used by the glass heater circuit is below a first predetermined value.
