DC Power Supplies

The new WAGO 787 Series power supplies provide a broad range of highly reliable, cost-effective dc power sources for any industrial control application. A new metal-clad housing offers a shockproof, industrial-strength, and compact DIN rail-mount design.

The 787 Series primary switch mode power supplies are available in single or 3-phase versions with input voltages of 90-Vac to 264-Vac or 325-Vac to 550-Vac output voltages of 12 Vdc or 24 Vdc, current ratings of 1.3 A, 2 A, 2.5 A, 4 A, 8 A, 10 A, or 20 A, and power ratings up to 480 W. These high-quality units offer high efficiency, overvoltage protection, short-circuit protection, surge protection and in-rush current limiting via NTC resistor to ensure operational reliability.

Other features include LED indication of the output voltage, output circuit connected in parallel for increased output current operation, adjustable output voltage via a potentiometer to compensate for voltage drop, and analog interface (Ua and Ia) for compiling output measurements.
