ADJH21024

The ADJH21024 from Panasonic Electric Works is a DJ-H power relay (ADJH). It is suitable for lighting and motor load applications. This relay is also used in applications like smart house (shutter and blind control) and lighting control applications. It has minimum insulation resistance (initial) of 1000Mohm at 500VDC measured portion is the same as the case of dielectric voltage. This power relay has high inrush capability (tungsten load (TV-20 class), electronic ballast load (NEMA410), capacitive load (IEC60669-1)). Dielectric strength (initial) is 1500Vrms for 1min (detection current: 10mA) between open contacts and 4000Vrms for 1min (detection current: 10mA) between contact and coil. The surge withstand voltage (initial) between contact and coil is 12000V, set time is maximum 20ms (initial) (at 20°C, rated voltage without bounce and reset time is maximum 20ms (initial) at 20°C, rated voltage without bounce. Minimum mechanical life is 1×10^6 (at 180 times/min).

Notes

It is recommended to apply rated voltage for minimum 100ms pulse across coil to secure sure operation considering ambient temperature and condition change through service life.
