The converters have been designed The outputs deliver an electrically-isolated Safety Extra Low according to the latest industry requirements and standards. Voltage (SELV) and low output noise. They are no-load, The converters are ideal for use in outdoor and other overload, and short-circuit proof. The electronically controlled demanding applications to power building control systems, short-term peak power capability of up to 150% of the rated factory automation, industrial controls, instrumentation, output power enables the front end converters to deliver electromagnetic drives, fans, and other DC loads. Different additional power to start-up motors or to safely operate models are available with a single output or two subsequent circuit breakers. Built-in large sized output independently regulated, electrically isolated outputs with 12, capacitors absorb possible reverse energy, which may be 24, 36, or 48 V. Special models for battery charging are caused by quick deceleration of electromagnetic drives available. The EW models are particularly suitable for 110 V connected directly to the output. A green LED at the front cover railway applications they have been designed in accordance displays the status of the output(s). with the railway standards EN 50155 and EN 50121. The Convert Select Series was designed according to all Key features of the Convert Select line include power factor relevant international safety standards. The converters are correction with low harmonic distortion, negligibly low inrush approved by TV and UL, and are UL 508 listed.
