Weidmuller PROeco, PROmax and PRO-H switchmode power supply units

The PROeco, PROmax and PRO-H have been added to Weidmuller’s range of switchmode power supply units.

The PROeco comes in single- and three-phase units with 12, 24 or 48 V. Suitable for use in field cabinets, flat distributor boxes or compact series machines, the device provides up to 93% efficiency, and minimal no-load losses ensure low energy consumption and long service life. The power packs also work from -25 to +70°C and have an MTBF exceeding 500,000 h. An integrated status relay for error detection allows for remote monitoring.

The PROmax, designed for light process applications and mechanical, plant and marine engineering, include single- and two-/three-phase models with output voltages of 5 to 48 VDC. The product features MTBF exceeding 500,000 h and a temperature range of -25 to +70°C. The unit delivers continuous power up to 120% at temperatures up to +45°C, while high output peaks up to 300% ensure safe operation. The product complies with surge protection category III and SEMI F47, and can be fitted side by side on a DIN rail to save space.

The PRO-H is suitable for special applications in power stations, and chemical, pharmaceutical and process industries. The single- and two-phase models provide an MTBF - up to 1.8 million h - for long service life. Withstanding temperatures from -25 to +70°C, the units are also shock and vibration proof. With ATEX and C1D2 approvals, they are suitable for use in explosive risk zones and also contain status alarms for remote observation.
