DATEL’s new DCA5-20PC Series dc ammeters are specifically designed to display
the output of all popular 50mV and 100mV dc-shunts. 25 input ranges provide for
precision measurement of dc currents from 1.000A to 2000A. With the exception of
an external shunt, the unit is 100% self-contained – no calibration or user-supplied
components are required. Available LED-display colors include brilliant blue, bright green,
and standard red. Three power supply options accommodate all popular dc-supply
voltages from 5V to 75Vdc, making these ammeters perfect for automotive, industrial,
telecom, and marine applications!
DCA5-20PC Series ammeters are housed in 1.38” x 0.88” (35mm x 22mm) rugged
packages that feature a large, 0.37”/9.4mm high, LED display. However, display visibility
is not compromised in any way: the display can be easily read at distances up to 15
feet (5 meters). All input and power supply connections are made by way of two screw-
style terminal blocks. For added flexibility, computer-style jumpers are provided for range-
specific decimal point assignments. And, to ensure trouble free installation, all models
include reverse-polarity protected power supply inputs.
Two input configurations are offered: grounded shunt (“low-side”), 5-40V-powered,
red LED models for cost-sensitive applications, and 8-36V isolated-supply models that
accept high-side or floating shunts. Isolated-supply models are available in a choice
of red, green, or blue LEDs. Since many dc ammeters are used in battery backup
applications, power consumption for 8-36V models is typically 1 Watt, and 75mW for
5-40V models.
Miniature size, wide supply inputs, and no-hassles installation make DCA5-20PC
Series ammeters the ideal choice for all your 50 and 100mV shunt ammeter-applications.
