Description
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.
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 (SELV) and low output noise. They are no-load,
