Product description
The LQT60 is a configurable 3-phase multi-transducer, capable for measuring any
electrical quantity of a network. It is possible to choose up to 5 of any electrical
quantities and link them to the analog outputs. Its 2 transistor outputs can be used to
energy pulses or alarm levels.
