DEMO MANUAL DC1739B-C
QUICK START PROCEDURE
a. If efficiency measurements are desired, an ammeter
or a resistor shunt that is capable of handling 10ADC
can be put in series with the output load in order to
measure the DC1739B-C’s output current.
b. A voltmeter with a capability of measuring at least 12V
can be placed across the output terminals in order
to get an accurate output voltage measurement.
7. Turn on the power at the input.
Note: If there is no output, temporarily disconnect the load
to make sure that the load is not set too high.
8. Once the proper output voltage is again established,
adjust the load within the operating range and observe
the output voltage regulation, ripple voltage, efficiency
and other desired parameters.
