Multi-Range Input Tolerance
Supports 85-264V AC (47-63Hz) and 88-300V DC inputs with automatic phase-balancing, achieving ≥0.95 power factor at 100% load (EN 61000-3-2 compliant).
Dynamic Load Sharing
Enables parallel operation of up to 4 units with ±2% current imbalance control via dedicated synchronization pins (terminals 18-19), requiring matched firmware versions.
Inrush Current Limiting
Soft-start circuitry restricts inrush to ≤25A/230V AC for 10ms during cold boot, compliant with NTC thermistor curve Class T.
Redundancy Transition
Seamless switchover ≤0.5ms between primary/backup units using isolated DC-link synchronization (24VDC ±1% ripple tolerance).
