measurement
5.8.4 Setting for maximum power (max. Power adjust)
h Apply the maximum controller output signal
h Turn the „max. Power adjust“ trimmer clockwise or counter-clockwise until
the required power is achieved.
h Turning the „max. Power adjust“ trimmer clockwise will increase the
maximum power output.
h Take care that the red „current limit“ LED remains off, otherwise the circuit
is operating in current limiting (current limit), which leaves turning the
trimmer clockwise without effect, as the power output will not increase.
5.8.5 Input signal attenuation
h Turning the „max. Power adjust“ trimmer counter-clockwise will decrease
the maximum power output of the converter.
5.9 Setting the base load (min. Power adjust)
Base load
setting Open switch S11 to be able to set a base load.
Turning the „min. Power adjust“ trimmer clockwise will increase the base load
setting.
The settable range covers the complete range from 0 to 100%.
Example: A heating system is operated with a base load set to 1/3. The remaining 2/3 of
the power are regulated by the controller.
Correct
measurement
Factory setting S101-11 is closed, no base load is set
A
A true-rms meter must be used for measuring voltage, power or
current, because the load current is pulsating DC.
A meter calibrated for alternating current (AC) and sinusoidal
waveforms will produce false readings!
