7.4: Notes
1. Primary voltage absolute value and drift are not specified. The LDX-3A uses ratiometric techniques to compensate for
primary voltage drift.
2. The way in which the LDX-3A functions means a special configuration must be used for transducers outside of the
standard range. This is selectable by links. The majority of Omega LVDT transducers are within the standard range.
The user manual provides details of the selection criteria.
3. LDX-3A can drive into a 1 kΩ load but this offers no advantage. 10-100 kΩ is recommended.
4. Output voltage range can be adjusted as required anywhere within this range by using a combination of gain and
offset, for example, ±10Vdc, ±5Vdc, 0-5Vdc, 0-10Vdc, 4-20mA. See user manual for adjustment method.
5. Current output may be used at the same time as voltage output. Calibration of voltage and current cannot be
individually adjusted.
6. Protection applies to the product when fully installed according to the user manual. During installation the top of the
enclosure has to be removed for access to user adjustments. At this time standard ESD handling precautions for
electronic equipment should be followed.
7. The LDX-3A complies with the toughest electrical emissions regulations. The power supply unit alone is only compliant
with BS EN61000-6-1:2001 (Immunity for residential, commercial and light-industrial environments). However, when
used as part of the LDX-3A assembly, the compliance levels are extended to BS EN61000-6-2:2001 (Immunity for
industrial environments). Compliance requires installation according to user manual. The flexibility of LDX-3A means it
can be installed in a variety of ways according to user requirements. Simple installations with short non-screened
cables will meet the lesser light-industrial immunity regulations. Heavy industrial installations, especially with longer
cables, will need more careful installation with screened cables.
