START-DELTA (Y-△) TIMER

FEATURE
FEATURE
• AT-PR is used for confirming the phase sequence of a three phase power to prevent the reversed running or loss phase of the motor.
• Detects the equipments that the input power is not allow to confusing phases or to reverse running.
• Voltage range; 3φAC200V, 220V, 240V, 380V, 440V.
　

　

　
• High reliability, anti-noise, multi-types.
• Adopting high quality, power saving, and stable COOS IC.
• High accuracy, repeated tolerance less than ± 0.3%.
• Short resetting time, less than 40 ms.
• Graceful knob, easy for setting and keeping the graduation clean.
• Owing to characteristics of anti-noise and anti-low voltage, suitable for bad surroundings.
• Quality been guaranteed by individual computer testing.
