Precautions when using TB relays power type

Coil operating power

Pure DC current should be applied to the coil. If it includes

ripple, the ripple factor should be less than 5%. However,

check it with the actual circuit since the characteristics may

be slightly different. Also, the power waveform should be

rectangular.

Coil applied voltage

To ensure proper operation, the voltage applied to the coil

should be the rated operating voltage of the coil. Also, be

aware that the pick-up and drop-out voltages will fluctuate

depending on the ambient temperature and operating

conditions.

Expected life

Check this with the real device as it is affected by coil driving

circuit, load type, activation frequency, activation phase,

ambient conditions and other factors.
