Unit description

Gertebeschreibung PMD s10

The true power converter PMD s10 is

used to measure and monitor the true

power drawn and output by electrical

loads.

The PMD s10 is designed for use as a:

` True power converter for single and

three-phase electrical machines

` Trip device for underload and over-

load

Electronic monitoring relays PMDsigma True power monitoring PMD s10 signals. The hysteresis of the switching thresholds can be set between 0% ... 50 %. Current transformer CT: With continuous currents > 12 A, the measuring current must be measured via an external current transformer. Po function (K1 overload): If the measured true power exceeds the switching threshold Po, the "> max" LED is lit.
