DMS-EB-RMS
AC-to-RMS Converter Application Board for DMS-30PC/LCD Meters
PRODUCT OVERVIEW
Description: The DMS-EB-RMS board allows the true rms value of ac signals to be displayed on
5V-powered DMS-30PC/LCD digital voltmeters. The meter/board combination has an input range of
0-750Vac with ±2V meters (1Vac resolution) or 0-199.9Vac with ±200mV meters (0.1Vac resolution).
A built-in screw-terminal block reliably interfaces signal and power connections. The DMS-EB-RMS
now accommodates user-installed modi?cations such as input-scaling resistors and isolated +5V dc/dc
converters.
Power and Safety Precautions: The DMS-EB-RMS’s AC HI and AC LOW inputs are not electri-
FEATURES
Displays true rms values of ac inputs
±0.5% accuracy for DMS-30PC-0 or DMS-
30LCD-0-5
±2% accuracy for DMS-30PC-1 or DMS-
30LCD-1-5
Also works with DMS-40PC/LCD meters (see Ap
Note 11)
cally isolated from its 5V supply (AC LOW is connected directly to 5V RETURN). When measuring any
input signal which is derived from ac power mains, a dedicated (i.e., it only powers the DMS-EB-RMS),
transformer-isolated +5V supply, with a minimum 1kV breakdown rating, must be used to power the
DMS-EB-RMS board/meter combination. When measuring ac power mains inputs, never connect the
DMS-EB-RMS’s 5V RETURN to chassis/earth ground anywhere in the system. Failing to follow these
instructions could defeat any safety grounding and will place the system +5V power supply, and all its
associated circuitry, at dangerously elevated ac-line potentials. In many applications, the MS-EB-RMS
installation is required to meet electrical code requirements. To ensure safe operation, the DMS-EB-
RMS board should only be installed and serviced by technically quali?ed personnel. See DMS
Application Note 11 for more details.
