LVDT signal conditioning card mod. EL646:
Mod. EL546 are SMD signal conditioning cards that need to be
fed, from external power supply (not included), a filtered and
stabilized power supply and then they feed the Vac power
supply to the primary coils of the connected LVDT.
The extractable female connectors are included.
The EL%46 output impedance is approximately 10 Ohm.
