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, electro magnetic 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. The outputs deliver an electrically-isolated Electrical energy source class 1 (ES1), (except models LXR/LXN1740) and low output noise. They are 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 converters to deliver additional power to start-up motors or to safely operate subsequent circuit breakers. Built-in large siz ed output capacitors absorb possible reverse energy, which may be caused by quick deceleration of electromagnetic drives connected directly to the output. A green LED at the front cover displays the status of the output(s). The Convert Select Series was designed according to all relevant international safety standards. Adequate clear ances and creepage distances allow operation in pollution degree 2 environment. All board assemblies are coated with a protective lacquer. The thermal concept allows operation at full load up to an ambient temperature of 60 C in free air without forced cooling. A rugged DIN snap-fit device allows easy and reliable fixing onto the various 35 mm DIN-rail models. The converters are fitted with cage clamp terminals easily accessible from the front. System connectors with screw terminals for use with pre-assembled harnesses, external adjustment of the output voltage, as well as various auxiliary functions are available as options.
