The converters have been designed according to the latest industry requirements and standards. The converters 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 12, 24, 36, or 48 V. Special models for battery charging are available. The EW models are particularly suitable for 110 V railway applications they have been designed in accordance with the railway standards EN 50155 and EN 50121. 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 Safety Extra Low Voltage (ES1) 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 sized 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. The converters are approved by Nemko and CSA and are UL 508 listed. Adequate clearances and creepage distances allow operation in pollution degree 3 environment (with AC input). 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 (LW models) or 70 C (EW models) 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 which are 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. The letter E stands for improved EMC performance of LW models. Models without E are obsolete.
