lamp dimmer การใช้

• Buoyed by that success, I hooked up the television remote and the lamp dimmer switch in the living room and the clock radio in the bedroom.
• Typically switching has to be done several times a minute in an electric stove, 120 Hz in a lamp dimmer, from few kilohertz ( kHz ) to tens of kHz for a motor drive and well into the tens or hundreds of kHz in audio amplifiers and computer power supplies.
• Baseboard heaters will especially benefit from a programmable thermostat which is capable of continuous control ( as are at least some Honeywell models ), effectively controlling the heater like a lamp dimmer, and gradually increasing and decreasing heating to ensure an extremely constant room temperature ( continuous control rather than relying on the averaging effects of hysteresis ).
