Product Description

The B&R Automation power supply, model 0PS340.1, is a robust 3-phase unit designed for demanding industrial applications, offering a 24 VDC output and supporting an input range of 400 to 500 VAC. This powerful supply unit delivers 40 A and is engineered for easy installation with snap-on mounting onto a top-hat rail. The unit measures 275 mm in width, 124 mm in height, and 117 mm in depth, including the top-hat rail, and weighs 3300 g. Efficient cooling is achieved through normal convection, eliminating the need for a fan. With a typical efficiency of 92.5% at 400 VAC and 24 V / 40 A, it minimizes energy loss, which is typically 78 W under these conditions. The device complies with EN 61000-6-3 (class B) for output noise suppression, ensuring reliable performance in noisy environments.

The B&R Automation power supply unit delivers a substantial 960 W of output power with a nominal voltage adjustable between 24 to 28 VDC (default setting: 24.5 V ~0.5%). Its power-back immunity is rated at 35 V, and it includes comprehensive protection functions such as short-circuit overload and no-load protection. Overvoltage protection is set at 32 V ~10%, transitioning to hiccup operation to prevent damage. The unit is safeguarded externally by three commercially available thermomagnetic circuit breakers. It also features an active transient filter, providing transient-proof performance per VDE 0160 / W2 standards.

Boasting a MTBF of 305,000 hours, the B&R Automation 0PS340.1 is designed for long-term reliability and durability in industrial settings. Its easy installation, high efficiency, and extensive protection features make it a superior choice for professionals in the industry. With its impressive output power and advanced safety features, the B&R Automation 0PS340.1 power supply unit stands out as a top-tier solution for modern industrial power needs.
