EP27 Moving-iron voltmeters

Voltmeters equipped with a change-over switch EP27 and EP29 type are designed to measure phase-to-phase and line-to-line voltages in low voltage power networks.

A switch installed on the left side of the dial enables the selection of the measured voltage. They are particularly useful for measurements in electrical machine safeguard systems.

 

Description

Lumel EP27 Moving-iron voltmeters with a change-over switch is adapted for measuring line-to-line and phase-to-phase RMS voltages in 3-phase 4-wire power networks.

A six-positional switch installed on the meter frontal side enables the choice of the measured voltage in six different points of the network system.

Category of Climate Versions:
If it is not stipulated in any other way, these EP27 Moving-iron voltmeters are designed to be applied in closed rooms, without air conditioning systems and in conditions of a moderate climate, in accordance to EN 60051 standard. You can request to adapt these meters to be applied  in dry  or wet tropical climate conditions and also in closed rooms without air conditioning. Then, they are marked with the TIII Symbol.

The Frontal frame dimensions is 72 x 72 x 64 mm.
