VII. Maintenance and Selection Suggestions

1. Spare Parts Selection

For old systems with full configuration, high-temperature working conditions, and high-reliability requirements, the 1D54582G05 model should be selected first, as it offers the largest power capacity, the strongest redundancy, the best heat dissipation, and the highest long-term operational stability. For those with limited budgets, original refurbished parts can be chosen, with a focus on testing output accuracy, full-load load capacity, redundancy switching function, fan operation status, and insulation performance.

2. Daily Maintenance

Monthly: Check the status of LED indicators, clean the dust on the casing and air ducts

Every 3 months: Check if the connection terminals are tightened and the connectors are oxidized

Every 6 months: Conduct full-load load tests to verify output voltage/current, ripple, and redundancy switching function

每年： Check the fan operation status， clean the air ducts， replace aging fans， and test insulation performance

3. Upgrade Suggestions

For new projects， the Ovation 4.0 platform's new high-efficiency power supply should be given priority； when expanding the old system or replacing spare parts， the same model 1D54582G05 should be matched for redundancy pairing to ensure compatibility and stability， avoiding system failures caused by insufficient power supply capacity.
