Wieland Electric’s phase control relays range has been extended by two new types of flare – the Control P3-L and the Control P3-LTN.
Unequal load distribution within the individual phases cause phase imbalances wherein part of the energy is converted into reactive power, meaning the efficiency of a connected motor and the thermal load will increase until breakdown.
The flare Control P3-L, the basic version monitors phase failure, phase sequence and phase position in three-phase systems within a voltage range from 200 to 500V AC.
The flare Control P3-LTN provides additional control functions such as voltage balance control with both the response delay and the connected power voltage being adjustable.
The phase control relays have a width of 22.5mm. These devices are equipped with a changeover and several diagnostic LEDs enabling a selective error search.
Wieland Electric’s new phase control relays have been approved in accordance with standards including UL/CE for application worldwide.
