-
No restrictions on distance between adapter and LV switchboard
Description
Voltage Adapter AN7 is used for Insulation Guard KPM163x, KRM16x and KCM16x or Insulation Transducer MCM163x, when the monitored line voltage is higher than 500VAC.
The adapter is a passive low-pass filter for use in 50, 60 or 400Hz networks, and is potted in polyurethane.
The unit includes high inductance reactance modules, connected in a special configuration to avoid DC saturation. The Adapter maintains a high AC suppression of its signal output to very low, safe levels, under all conditions.
Alternative connections to the AC network are shown below. Connection to the star-point (Neutral) is preferable.
Specification:
Voltage range: Up to 7000VAC
Dimensions:
360 x 180 x 200mm
