(R) (R) DMS Accessories 5 Volt, Isolated and Non-Isolated DC/DC Converters for DMS Series Meters Order on-line at www.datel.com 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 application requiring isolation is high-side, current-shunt, dc ammeters (see DMS Ap Note 6 for information on dc ammeters). Any 5Vpowered, 31/2 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 41/2 digit meter applications by simply adding filter components to the converter's output pins.

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. 0.151 0.002 (3.835 0.05) 0.40 0.02 (10.16 0.5) 0.18 0.005 (4.57 0.13) Typical Circuit GND Input + Output 0.34 0.01 (8.64 0.25) 7805 0.1uF 0.54 0.015 (13.72 0.4) Input C2 GND 0.1uF Notes: 1.
