... For full details go to www.murata-ps.com/rohs Murata Power Solutions’ new DMS-30DR Series are the fi rst digital panel meters to offer LED displays that are readable in direct sunlight—no special fi lters or shading devices are required. Their Autodim circuit automatically adjusts the display’s brightness to suit viewing environments ranging from total darkness to full, brilliant sunlight ...

... External drivers will see approximately 600Kohms referenced to 5V RETURN. With pin 2 at +0.7Vdc or below, the DMS-30DR’s LED display is off, and total cur- rent drain from a nominal +5V supply is approximately 1mA. The LED display’s brightness will increase from minimum to maximum as the voltage applied to pin 2 is varied from +0 ...

... RETURN). 1. Single-Ended Input Confi gurations: True single-ended measure- ments can be made with any DMS-30DR meter. The circuit of Figure 2 avoids problems normally associated with ground-loop currents. Separate ground runs should be used for 5V RETURN (pin 3) and (–) INPUT LO (pin 12). This will ensure that large LED currents will not fl ...

... APPLICATIONS 2. Differential Input Confi gurations: Differential measurements can be made with all DMS-30DR meters. Figure 3, though not a practical real- world application, uses a voltage divider to demonstrate the concept of a differential input signal. Be careful not to exceed the ±2V common mode voltage limitation for 5V-powered meters. ...

... Use the +1.225V REFERENCE OUT (pin 9) for applica- tions needing external gain adjustment. Figure 10 shows the wiring confi guration for each model. Calibration is performed with a precise, near-full-scale, input voltage. Figure 9. External Gain Adjustment email: sales@murata-ps.com 03 Aug 2010 MPM_DMS-30DR.B05 Page ...
