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
Safety according to IEC/EN 60950-1, UL/CSA 60950-1,
IEC/EN 50178, IEC 61010-1, UL 508
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, (except models LWR/LWN1740) 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 TV and UL, and are UL 508 listed. Adequate
