DCA5-20PC Series
50mV & 100mV Input, LED-Display,
Subminiature DC Ammeters
APPLICATIONS
8. Operation With 100mV Shunts: Many DCA5-20PC Series ammeters
can also operate with 100mV shunts. This is due to the fact that when
they are driven by a 100mV input, the display readings are double
those of a 50mV input. However, a 50mV shunt cannot be used in
a 100mV application because its maximum current rating will be
exceeded.
For our customer’s convenience, DATEL offers a series of 50mV and
100mV chassis-mount dc shunts that can be used with DCA5-20PC
ammeters. Part numbers for accessory shunts can be found in the
Ordering Information section. A data sheet describing these shunts is
20PC’s sensitive circuitry. The ampli?ed noise introduces errors that are
particularly noticeable at zero load current (i.e., the ammeter may not
display a relatively steady “000” reading).
Connecting an external, unpolarized capacitor across TB1’s “+” and
“–” inputs, and/or across the shunt’s 50mV output terminals, can help
reduce noise-related display errors. In certain situations, the use of
twisted pair or shield wiring may be required. As a general rule, avoid
using excessively long leads between the ammeter and the shunt.

Table 1 indicates the obtainable readings of the seven DCA5-20PC
models that can be operated with 100mV shunts. Be sure to enable the
correct decimal point (see decimal point selection instructions).
9. Noisy Power Supplies: Some power supplies contain high-frequency
switching devices that may conduct and/or radiate signi?cant noise
onto the low-level 50/100mV shunt signal. Even though the DCA5-
20PC incorporates built-in ?ltering at its shunt input, some portion of
this noise may be ampli?ed and subsequently measured by the DCA5-
Model

PANEL INSTALLATION
All connections and modi?cations must be made after the ammeter
is securely attached to the panel, with all load and supply voltages
de-energized (off).
The installed wire-positions should be such that minimal forces are applied
to TB1, TB2, and the ammeter itself. In high-vibration environments, the
use of wiring strain-reliefs is recommended.
To insure a secure panel-mount installation, MPS recommends using the
DMS-BZL4-C (with sealing gasket) bezel assembly supplied with each
ammeter. See the Mechanical Speci?cations section for detailed panel
cutout and ammeter dimensions.
Following the four-step sequence shown in Figure 8 below, being careful
not to apply excessive force or twisting motions, insert the ammeter into
the panel opening. When using the DMS-BZL4-C’s sealing gasket, make
sure it is positioned between the ammeter’s ?ange and the panel’s front
surface. Be sure to use and securely tighten all four screws supplied with
the bezel assembly.
