Weidmüller PRO series power supplies

Weidmüller has released its PRO range of switched-mode power supply units, known as the PROeco, PROmax and PRO-H.

The PROeco models are available in single- and three-phase units, with a choice of 12, 24 and 48 V models. Suitable for use in field cabinets, flat distributor boxes or compact series machines, the PROeco series provides up to 93% efficiency and minimal no-load losses. They have an MTBF value of more than 500,000 h.

The PROmax switched-mode power supply units have been designed for demanding applications in mechanical and plant engineering, light process applications and marine engineering. The range includes single- and two-/three-phase models and output voltages of 5-48 VDC are available. They also feature MTBF values exceeding 500,000 h, while start-up temperatures of -40°C make them particularly robust. The units can deliver continuous power of up to 120% at temperatures up to +45°C and high output peaks up to 300% ensure safe operation.

The PRO-H family is suitable for special applications in power stations and chemical, pharmaceutical and process industries where reliability is absolutely critical. The single- and two-phase wide-voltage power supply models provide a high MTBF - up to 1.8 million hours - for a long, reliable service life. Robust and durable, the units are both shock and vibration proof and are suitable for use in explosive risk zones.

All three models of the PRO range of power supplies work in a wide temperature range from -25 to +70°C.
