The convert select front end series represents a family of DIN-rail mountable DC-DC and AC-DC converters with power factor correction. The converters have been designed according to the latest industry requirements and standards. They are ideal for use in outdoor and other demanding applications to power building control systems, factory automation, industrial controls, instrumentation, electromagnetic drives, fans and other DC loads. Different models are available with a single output or two independently regulated, electrically isolated outputs with 24, 36, or 48 V. Special models for battery charging are available. Key features of the Convert Select line 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 lockout, thermal protection, as well as output overvoltage protection by a second control loop ensure safe operation of the final system.
