What to do if my SAJ PDS23-2SR75 Controller is overheating?
- G
  Gail ReyesAug 22, 2025
  The SAJ Controller may overheat due to several reasons: * Instantaneous over-current: Refer to over-current remedy. * Output short circuit: Re-wire the output. * Cooling fan issues or ventilation obstruction: Replace the cooling fan and clear the ventilation channel. * High ambient temperature: Decrease the ambient temperature if possible. * Loose cables or terminals: Inspect and tighten the wires and terminals. * Abnormal power circuit: Ask for support.
