Description

The DQLe and KDQLe series power factor meters are used to measure the power factor in AC and three-phase networks. DQLe power factor meters have a 90° scale and KDQLe circular scale devices have a 240° scale. A choice can be made between direct measurement of the power factor (linear cos?-scale) and measurement of the phase shift angle (non-linear cos?-scale).
