Application
This unit is used for the supervison of Singel, Double or Triple Phase Voltage Supplies
Functions :
The phase of the voltage supply are fed to an electronic measuring system. Units with one system for over or under voltage and units with two system for Over and Under voltage can be supplied. A small signal lamp lights up as long as the supplied voltage is within the adjusted limits. The signal lamp extinguishes and two output contacts are switched the moment one phase exceeds or falls below the limits.
Technical data of standard design :
Type : WK N 3-2 with two switch points for under-over voltage
Voltage : For double, triple or four pole connection p.t.o
Ratio between switching on and off : 1%
Repeat Accuracy (8 – 600) : ± 0,5 = % changing all phase : 2 = % changing two phase, two constant : 4 = % changing one phase, two constant
Switching-on delay = ms, - Other delays on request
Switching-off delay = ms, - Other delays on request
