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:
