Power supply
Ekip Com Synchrocheck is supplied directly by the Ekip Supply module to which it is connected.
NOTE: communication between Ekip Touch and the module is interrupted in the absence of
auxiliary power supply
Input
Ekip Synchrocheck has an input (V S1 - V S2) for reading voltage, operation of which is ensured within the
ranges and with the performance given below:
Component Operating range Normal operating range
Accuracy
(1)
Voltage 0÷120 VAC 10 ÷ 120 VAC 1 %
(2)
Frequency
(3)
30÷80 Hz 30 ÷ 80 Hz 0,1 %
(4)
Phase
(5)
- -180 ÷ +180 ° 1 °
(1)
the accuracy values refer to normal operating ranges, as established by IEC 61557-12
(2)
with busbar activated
(3)
with the busbar activated, frequency measurement starts at ≥ 36 V AC and ends at ≤ 32 V AC measured
voltage
(4)
in the absence of harmonic distortion
(5)
phase measurement refers to the phase difference between internal and external voltage
Isolation transformer
An isolating transformer with the characteristics given below must always be installed between the external
contacts of the circuit-breaker and the input of the module:
