Supply Voltage - TE LDM-1000 Operation Manual

LDM-1000
LVDT/RVDT Signal Conditioning Module
The list below is the minimum information required to perform a successful calibration:


Recommended LVDT or RVDT excitation frequency (to set the oscillator frequency)

LVDT or RVDT Output sensitivity at the excitation frequency (to set the gain)

Primary (input) impedance at the excitation frequency (to set the oscillator output voltage)

The ± full scale linear or angular range over which you intend to perform the calibration
Analog output signal required by your application

4. 1. Supply Voltage

The LDM-1000 supply voltage range is 18~30 VDC with the JP1 jumper in the storage position (as shipped position). Only this
range (18~30VDC) can be used for 4-20mA output operation. The operating voltage may be changed to 10~18 VDC by installing
internal jumper JP1 across both pins. See the diagrams below for jumper settings.
CAUTION: Operating the unit at voltages above +18 volts with the jumper in the low voltage position will overheat
the internal voltage regulators and reduce the operational life of the LDM-1000.
