Common Failures
Units received for evaluation commonly exhibit open power fuses and defective bus capacitors, which may appear domed. These conditions can result in the unit being non-operational. Other components, such as the output module and relays, typically show no faults upon inspection.
Repair Approach
Repairs typically involve replacing defective power fuses and bus capacitors. Additional capacitors may be replaced as a preventative measure to support long-term reliability. If terminal screws are found to be missing during evaluation, replacements are installed.
Testing & Quality
Post-repair testing includes powering the unit with a 220Vdc supply and verifying that charge and power LEDs function as expected. Basic diagnostic procedures are performed. A burn-in test without load is conducted to confirm initial functionality. Further testing at the machine or system level should be completed by the customer upon receipt.
