DMS-20PC digital panel voltmeters

Murata Power Solutions has announced that its low-power, high brightness, three-and-a-half digit, DMS-20PC digital panel voltmeters are now available with 'brilliant blue' or 'pure green' LED colors in addition to the current 'low-power red'. The DMS-20PC series provides a sub-miniature, low-cost solution in applications such as battery chargers, power amplifiers, rack-mounted power and high-end consumer electronics.

Advances in LED Technology have allowed Murata Power Solutions to offer the two new colors. Innovations in LED drive circuit technology and used in the DMS-20PC range enables low power consumption of 12- to 17mA for blue and green LED models, and 7- to 12mA for red LED versions (all @ +5Vdc). This compares to the 150mA to 200mA range seen in competing products. The low-power performance has been achieved without a reduction in LED brightness.

Housed in an epoxy-encapsulated 12-pin DIP package with a built-in color filter and bezel, the DMS-20PC series offers component-like plug-in convenience and is moisture and vibration proof making it well-suited to use in the harshest environments. Operating temperature range is 0C to +60C. The fully self-contained and fully functional meters combine a precision ADC and a factory-trimmed, highly stable voltage reference.

Powered by a single +5V supply, the DMS-20PC has four differential input voltage ranges: 200mV, 2V, 20V or 200V, input overvoltage protection (on the non-inverting input) is 250V. All models have a factory calibrated 1 count accuracy (0.05 percent of full scale range) and are designed to never require calibration.

The compact overall package dimensions of 35mm x 22mm x 12mm are only slightly larger than the 9.4mm high display, helping to maximize use of space in customer applications.

In addition, the DMS-20PC features a DISPLAY TEST function and a DISPLAY ENABLE function that permits the display to be disabled for 'power-down' operation. 'Standard red' LED models also offer an optional DISPLAY HOLD function.

DMS-20PC low-power blue or green LED display panel meters are priced at $54 in singles and drop to below $37 in hundreds. Small quantities are available from stock.
