General purpose miniature power relay that can be used for a wide range of applications from control to power.

DI series¥ Features
ï Boasting high reliability and achievements, with an input current of 80A, carry and cut-off current of 20A,
0 it is suitable for motor load of compressor of air conditioners.
ï PCB type and TMP type (with tab terminal for contact and PCB terminal for coil and contact signal) are prepared.
ï Small size, easy to use 1-pole type, ideal for inverter power supply for air conditioners (input current 200A peak1cut off 20A).
ï Insulation structure with high noise resistance.
