Murata Power Solutions' low-power, high brightness, three-and-a-half digit, DMS-20PC digital panel voltmeters are now available with 'brilliant blue' or 'pure green' LED colours 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 developed by Murata Power Solutions and used in the DMS-20PC range mean that power consumption is just 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 seen in many competing products. This low-power performance has been achieved without a reduction in LED brightness - in fact, DMS-20PC LED panel meters are brighter than many standard power counterparts.
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 0°C to +60°C. The fully self-contained and fully functional meters combine a precision A/D converter 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% of full scale range) and are designed to never require calibration.
The compact overall package dimensions of 35mm (1.38in.) x 22mm (0.88in.) x 12mm (0.48in.) are only slightly larger than the 9.4mm (0.37in.) high display itself therefore helping to maximize use of space in customer applications.
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.
