WATT METERS

WATT METERS

WA - 144

WA - 96

Beemet Watt meters are available in Single Phase, 3-Phase balanced load 3 or 4 wire, and 3-phase unbalanced load 3 or 4 wire configurations. They are used to indicate import – export (reverse – forward) power flow. These can be utilized on both sinusoidal and non-sinusoidal currents.

These meters are designed to an internationally accepted standard. The dimensions comply with the requirements of DIN 43700 and scales with DIN 43802. The performance confirms to IS 1248-83/93. The cases are made of ABS plastic material which has high tracking index for maximum electrical strength and safety.
