The LEL14 is the basic 3 digit model, ideal for general monitoring on 3 and 4 wire, balanced and unbalanced power circuits.
The alarm relay can be assigned to any measurement variable. Crest factor max. 2
The LEL13 has 4 digits, for greater resolution.
The LEL10 offers the greatest flexibility. It allows you to have up to 20 pages of display combinations.
In addition, it computes the total Harmonic distortion of the current and voltages, up to the 25th harmonic. Ideal for monitoring variable speed drive performance and any other source of generated power, where waveform purity may vary.
Generator Synchronising unit
The LEL3 synchronising unit comprises of a 360 degree synchroscope and differential voltmeter in a 96 x 96mm panel mounting unit.
Horizontal bargraphs show Frequency and Voltage mismatch. A relay output activates when the generator is within the acceptable band of matching for phase, frequency and voltage.
