Glentek GA370-3 board

Glentek GA370‑3 is a high‑power PWM servo amplifier board designed for use with Glentek GM4050 brushless servo motors, providing precise torque control and high bandwidth drive signals. Common failure points on this class of boards include overheating or failure of power MOSFETs, electrolytic capacitor degradation, overcurrent protection trips, and loss of encoder feedback due to damaged signal traces or connectors. First‑check diagnostics should verify the 48 V (or specified) supply voltage, inspect for bulging or leaking capacitors, test MOSFET gate drive integrity, and confirm encoder/feedback signals are present before proceeding with component replacement or board rewiring.[oss-gpt-20b]
