Offering all the outstanding features and benefi ts of Murata Power Solutions’ industry leading DMS-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.

DMS-30LCD devices operate from a single +5V supply or a 9V battery. Battery-operated 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 Murata Power Solutions’ unique low-power LED meters in those circumstances.

Offering 4 optional input voltage ranges (±200mV, ±2V, ±20V or ±200V), DMS-30LCD 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.

Each meter incorporates an extremely stable, double regulated reference and is fully 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 recalibration.

For popular applications (4-to-20mA, rms-to-dc conversion, ac line power, J and K thermocouples, etc.), the DMS-30LCD Series includes a complete line of plug-on application boards that conveniently convert your meter into an application-specifi c instrument.
