DATEL's DMS-30PC/LCD Series, 3½ Digit, LED/LCD Display, Digital Panel Voltmeters. This
add-on board is ideal for applications requiring isolation (up to 750V) between the input
signal and the meter's +5V supply.
These ammeters typically have the current shunt located on the positive side of the power
supply — a condition which usually exceeds the meter's common mode voltage limit.
Input-to-output isolation is required if the power source being measured also powers the
DMS-30. DATEL's new Panel Meter Catalog has a detailed application note on dc amme-
ters.
board; the only exception being the smaller allowable range of power supply voltage when
using the LM7805 3-terminal regulator. Use the DMS-EB-DC/DC with any DMS-30PC meter
or DMS-30LCD meter (5V-powered models only).
tab adjacent to U1. Applications requiring a lower dropout voltage should consider the
LM2931T-5. Exceeding the
allowable regulator input voltage
ranges (see Functional Specifica-
tions) will cause device over-
heating! As is the case when
specifying any electronic power
component, be sure to consult all
applicable manufacturer's data
sheets.
