Danger! High voltages are present inside the unit. Do not reach inside while it is energized. To measure voltage,
!
de-energize the unit, connect the meter, and then re-energize the unit.

6.1 Checking with Voltmeters

All input and output voltage measurements should be made with a true RMS voltmeter. A certain amount of harmonics in the
output may cause other types—particularly rectifier types—to give inaccurate indications.

6.2 rating Characteristics

The MCR series are built for several VA ranges. See the label of each regulator for appropriate data.

6.3 Load regulation

Changes in output voltage resulting from changes in resistive loads, from no load to full load (100% pF), are approximately 4%.

6.4 effect of Load Power Factor

"Median" value of output voltage will vary from the label rating if the load has a power factor different from the unit's design. Load
regulation will also be greater as the inductive load power factor is decreased. However, the resulting median values of output
voltage will be regulated against supply line changes at any reasonable load or load power factor.
