Product Description

Introducing the B&R Industrial Automation's 0PS310.1, a powerhouse 24 VDC power supply unit tailored for rigorous industrial applications. This 3-phase unit accepts an input range of 400 to 500 VAC, delivering a steady output of 10 A, ensuring optimal performance and reliability. Designed for seamless installation on a top-hat rail, it boasts stable screw clamp terminal blocks suitable for flexible wires with a cross-section of 0.5 to 4 mm^2 and inflexible wires of 0.5 to 6 mm^2. Status indicators include a red LED for fuse mode cutoff and a green LED for operation, providing clear and immediate visibility of its status. Compliance with EN 61000-6-3 (class B) ensures minimal output noise, guaranteeing clean and stable power delivery.

This power supply unit features an impressive output power of 240 W, with a nominal voltage adjustable between 24 to 28 VDC (default setting: 24.5 V ~0.5%). It has a power-back immunity rated at 34 V and includes extensive protection functions such as short-circuit overload and no-load protection. The overvoltage protection is typically 36 V, with a maximum of 39 V, safeguarding connected devices. The permissible output load varies with temperature, providing 24 V / 12 A or 28 V / 10.3 A (288 W) at temperatures up to 45 degrees C, and 24 V / 10 A or 28 V / 8.6 A (240 W) at temperatures up to 60 degrees C.

Additionally, the unit boasts a MTBF (reliability) of 525,000 hours in 2-phase operation and 543,000 hours in 3-phase operation, underscoring its durability and long-term dependability. Its efficiency in 2-phase operation is typically 90.9% with a power loss (PV) of 24.5 W (400 V), while in 3-phase operation, the efficiency reaches 91.2% with a power loss of 23.6 W (400 V) and 92% with a power loss of 21.4 W (500 V).
