Electrical Specifications (Isolated)
➀ When used with the following DMS Series panel meters up to +60°C max.
Electrical Specifications (Non-Isolated)
Isolated: These miniature, 5V-output dc/dc converters are ideal
for applications requiring isolation between the input signal being
measured and the panel meter’s +5V power source. They can
eliminate common mode voltages up to 750V. A popular applica-
tion requiring isolation is high-side, current-shunt, dc ammeters
(see DMS Ap Note 6 for information on dc ammeters). Any 5V-
powered, 3½ digit, DMS Series meter whose supply current
does not exceed 225mA may be powered from these converters.
Low-noise operation can be obtained in most 4½ digit meter
applications by simply adding filter components to the converter’s
output pins.
Non-Isolated: The LM7805CT (DATEL part number 39-0304000)
is a highly reliable, three-terminal IC regulator that provides a
non-isolated +5V output from input voltages between +7.5 and
+28Vdc. However, when it is used to power DATEL DMS Series
panel meters, the allowable operating input voltage applied to the
LM7805CT should not exceed the ranges specified in the table
below.The LM7805CT can be used with the DMS-EB, DMS-EB2
and DMS-EB-DC/DC application boards; each board is pre-wired
to accept the regulator. Refer to each board’s data sheet for more
information. Please consult DATEL’s Application Engineers if you
have any questions regarding the use of dc/dc converters with
any DMS Series meter.
