DC/DC converters in 6mm-wide terminal block

Wago Corporation’s Engineering Services Division has developed DC/DC Converters that pack the characteristics of a 110 V power supply into a 6mm-wide DIN-rail terminal block. Traditionally, driving low-current circuits, e.g., analog transducers at 10 V, within a control panel requires an extra 110 V power supply. The 859 Series DC/DC Converters eliminate redundant power supplies for 5–12 V applications, including running 24 VDC sensors and other controls on battery power. The touch-safe, 859 Series DC/DC Converters may also trim safety-related expenses. Engineering Services manager, Carey Perschke, explains that costs increase exponentially when isolating control panel segments for low-voltage circuits.  All 859 Series DC/DC Converters feature short-circuit protected outputs, reverse voltage protection (input) and TVS diode protection. Line regulation from 0.5 per cent to 2 per cent (varies per model) ensures power consistency. Efficiency up to 85 per cent limits heat generation and power draw.
