TRANSFER-MOLD TYPE

INSULATED TYPE

[C] Under-Voltage Protection (Upper-arms, UVDB)

a1. Control supply voltage rises : After the voltage level reaches UVDBr, the circuits start to operate when the next input is applied.

a2. Normal operation : IGBT ON and carrying current.

a3. Under voltage trip (UVDBt).

a4. IGBT OFF in spite of control input condition, but there is no FO signal output.

a5. Under voltage reset (UVDBr).

a6. Normal operation : IGBT ON and carrying current.
