Nuvatec 8707 power switch board

The Nuvatec 8707 is a power‑switch board used to isolate and control battery or motor power in industrial vehicles and equipment. Common failure modes for this class of boards include burned or tripped relays, damaged MOSFETs or gate drivers, shorted isolation contacts, and degraded PCB traces from vibration or corrosion. First‑check diagnostics: verify the input supply voltage and polarity to the board; inspect all relay contacts and MOSFET packages for physical damage or burn marks; check continuity of the isolation circuit and confirm that the control signals are reaching the driver ICs without floating inputs.[oss-gpt-20b] Post Comment
