20LCD Series of 3½ Digit LCD Panel Meters, DMS-30LCD meters offer larger, more easily
readable displays at slightly higher power consumptions. Like all DMS Series LCD meters,
these miniature (2.17” x 0.92” x 0.43”), epoxy-encapsulated devices offer component-like
ease-of-use, outstanding reliability and easy installation in either panels or pc-cards.
ated units typically draw 350μA and consume a mere 3.2mW. Backlit models are available
for low-light applications; though we have found many designers prefer DATEL’s unique
low-power LED meters in those circumstances.
meters have an extremely user-friendly input structure. They can be used in differential
or single-ended modes. Input impedance is a minimum 800kΩ. CMRR is typically 86dB.
CMV is ±2V, and inputs are overvoltage protected to ±100V.
calibrated at our factory prior to encapsulation. We guarantee outstanding initial accuracy
(±1 count) and excellent stability over temperature (±0.15 counts/°C). These extremely
rugged meters are moisture and vibration proof and never require adjustment or recalibra-
tion.
