Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang INTERMATIC dari 3G Electric.
What is the difference between astronomic and non-astronomic INTERMATIC timers?
Astronomic INTERMATIC timers, such as the ET2805C, automatically adjust on/off times based on the date and geographic location, following sunrise and sunset patterns. Non-astronomic models, like the ET2145CR, operate on a fixed 24-hour or 7-day schedule set by the user. Astronomic functionality is useful for outdoor lighting that needs to track seasonal daylight changes without manual reprogramming.
Can INTERMATIC digital timers be used outdoors?
Yes, certain INTERMATIC digital timers are rated for outdoor use. For example, the ET2145CR has a metal body and is specified for outdoor installation. The ET2745CP also carries an outdoor rating but uses a plastic body. Always check the product's indoor/outdoor usage specification to ensure suitability for the environment, especially regarding moisture and temperature extremes.
What voltage ranges do INTERMATIC electronic timers support?
INTERMATIC electronic timers typically operate on 120-277V AC, covering common single-phase voltages in commercial and industrial settings. Models like the ET2145CR and ET2805C are rated for this range. Always verify the voltage rating on the specific model to match the supply voltage, as some units may have narrower ranges.
How do INTERMATIC spring-wound mechanical timers work?
INTERMATIC spring-wound timers, such as the FD5MW and FD30MWC, use a mechanical spring mechanism to time a single cycle. When the knob is turned, the spring winds and the timer runs for a preset maximum duration (e.g., 5 or 30 minutes). After the cycle, the switch returns to its default position. These timers require no external power for timing and are rated for 277V AC SPST switching.
What is the stem diameter on INTERMATIC photocontrols?
INTERMATIC fixed stem-mounted photocontrols, like the K4141C, have a 1/2-inch stem diameter. This standard size fits most threaded conduit openings or mounting fixtures. The photocell includes a washer gasket for weather sealing. It operates at 120V AC with SPST switching, turning loads on at dusk and off at dawn.
