triac การใช้

• Halogen torch鑢es usually have a TRIAC dimmer circuit built into the stem.
• New " triac clamping " protection circuit was incorporated to prevent arcing.
• Currently, the effect of Triac is under investigation.
• :The motion sensor probably has a thyristor or triac switch in the output.
• The worrisome products contain the ingredient tiratricol, another name for the thyroid hormone TRIAC.
• :: : Not actually the triac itself, but the circuitry controlling the triac.
• :: : Not actually the triac itself, but the circuitry controlling the triac.
• The TRIAC has a top speed of and a range of, according to the manufacturer.
• A light-activated TRIAC resembles a LASCR, except that it is designed for alternating currents.
• In this setup triac turn-on delays will compound, so quick turn on times are important.
• In AC circuits, SCR or TRIAC relays inherently switch off at the points of zero load current.
• This will mask the gate's supposed diode-type behaviour when testing a TRIAC with a multimeter.
• A zero cross circuit works to correct this problem, so that the triac functions as well as possible.
• This uses a single phase controlled triac to provide a variable voltage AC output for regulating a universal motor.
• However, due to the separate gates, proper triggering of the SCRs is more complex than triggering a TRIAC.
• Moreover, they are compatible with TRIAC-based variable-speed controls, which often are used with fans.
• This ensures that the TRIAC is triggered in quadrants II and III and avoids quadrant IV where TRIACs are typically insensitive.
• Since Triac bought Snapple for $ 300 million, sales have stabilized after falling 22 percent during the two-year Quaker regime.
• Digital thermostats use either a relay or a semiconductor device such as triac to act as a switch to control the HVAC unit.
• In 2014, a case was demonstrated in which therapy with TRIAC in early childhood led to significant improvement of cognition and mobility.
