AC-DC power converters

The Convert Select front end line from Power One is a family of DIN-rail mountable AC-DC converters with power factor correction. The converters are suited for use in demanding applications such as power building controls, factory automation, industrial controls, PLCs, instrumentation, electromagnetic drives, fans and other DC loads. The units are available with single or independently regulated, electrically isolated double outputs for 24 or 48 V loads.

Key features include: power factor correction with low harmonic distortion, negligibly low inrush current, high immunity to transients and surges and low electromagnetic emissions. Internal protection circuits such as input over- and undervoltage lock-out, thermal protection, as well as output overvoltage protection by a second control loop ensure safe operation of the final system.

The outputs deliver an electrically isolated safety extra low voltage (SELV) with low output noise. The Convert Select line is also no load, overload and short-circuit proof. The electronically-controlled short-term peak power capability of up to 150% of the rated output power enables the front end units to deliver additional power to start-up motors or to safely operate subsequent circuit breakers. Built-in large-sized output capacitors absorb possible reverse energy which may be caused by quick decelerations of electromagnetic drives.

The Convert Select line is built according to international safety standards. The thermal concept allows operation at full load up to an ambient temperature of 60°C in free air without forced cooling. A unique feature is the extremely small and compact design of the metallic case. The units are fitted with front accessible cage clamp terminals.
