B&R 3PS465.9
The unit incorporates active PFC (Power Factor Correction) achieving power factor > 0.95 at full load. Built-in protections include: short-circuit protection (auto-recovery), overcurrent protection, overvoltage protection, overtemperature protection (thermal shutdown at 85°C internal). A DC OK relay contact (changeover, 250 V AC / 5 A) provides status signaling to the host controller. The wide input voltage range (323–528 V AC) ensures uninterrupted operation during grid voltage sags and swells.
