Functional Description
The W Series converters are primary controlled AC-DC or DC-
DC flyback converters with a constant switching frequency of
130 kHz. The power-factor-corrected single-step conversion of
the input voltage to a low output voltage results in extremely
high efficiency. Depending upon the output power, the
converters are fitted with one (125 W) or two (250 W)
powertrains. Models with two powertrains have one or two
outputs. Double-output models exhibit indiviually regulated
powertrains.
The input voltage is fed via fuse, filter, and rectifier to the main
transformer, designed in planar technique. The input filter with
very small input capacitance generates virtually no inrush
current. An input transient suppressor protects the converter
against high voltage peaks and surges. Input over- and
undervoltage lockout as well as input current limitation protect
the converter from operation outside of its specification. The
input voltage waveform is sensed by the primary control logic
voltages and currents, degree of protection, batch no., serial
no., and data code including production site, version, and date
of production.
The secondary side of the main transformer supplies via the
rectifier diode a large electrolytic output storage capacitor
providing for the hold-up time. Double-output models exhibit
an individual control logic each. The output voltage and the
output current are measured and fed back to the primary
control logic via an optocoupler. A second control loop
monitors the output voltage. It disables the output in the case
of a failure in the control logic and limits the output voltage.
Built-in temperature sensors monitor the internal temperature
of each powertrain. If the temperature exceeds the limit, the
converter reduces the output power continuously to keep the
temperature below its limit. A green LED on the front cover
confirms the presence of the output voltage(s).
The R input (option R, M1, or M2) allows for external
adjustment of the output voltage by means of a resistor or an
external voltage source. An external sensor can be connected
to the R input and allows for temperature-controlled battery
charging (see Accessories ).
to allow active power factor correction, forcing the input current
to follow the input voltage waveform.
