OWNERS MANUAL
DCS30 Series
Hall-Effect Current Sensors
INTRODUCTION
The DCS30 Series family of Hall-effect DC current sensors is designed to operate standard 50 or 100 millivolt ammeters.
Although typically used in vehicle and marine applications to measure battery currents, they are suitable for any DC
current monitoring. The sensors measure positive and negative current values. Models are available for measuring
current ranges from +/- 100 amps up to +/- 600 amps, and they can output to either a +/- 50 millivolt meter or a +/- 100
millivolt meter.
DC Current Sensor Models
Model Current Range Output Model Current Range Output

DCS30-200-1 ± 200 amps ± 50 millivolts DCS30-500-1 ± 500 amps ± 50 millivolts
DCS30-300-1 ± 300 amps ± 50 millivolts DCS30-600-1 ± 600 amps ± 50 millivolts
DCS30-100-2 ± 100 amps ± 100 millivolts DCS30-400-2 ± 400 amps ± 100 millivolts
DCS30-200-2 ± 200 amps ± 100 millivolts DCS30-500-2 ± 500 amps ± 100 millivolts
DCS30-300-2 ± 300 amps ± 100 millivolts DCS30-600-2 ± 600 amps ± 100 millivolts

INSTALLATION
1. Getting Started
Before starting, make sure you have the correct connector plug parts, cable, sensor mounting bracket and screws, and
tools. Exercise appropriate caution when working with vehicle battery systems and ensure battery is disconnected during
installation.
Determine the location for mounting the sensor and the required cable length and routing to the meter. Avoid mounting
the sensor close ot very hot engine parts such as the exhaust manifold.
2. Installing the Sensor
Mount the sensor and route the battery cable through the aperture. The sensor may be secured to the battery cable using
tie wraps or a customer-made mounting bracket. If using a bracket, use 3 #6 self-tapping screws to attach the sensor via
the three bracket holes. Make sure the screws do not protrude more than 0.30 inches into the sensor.
Be sure to mount the sensor in the proper direction to ensure correct measurements of charging (plus) and discharging
(minus) battery current. See below diagram for suitable sensor mounting locations:
3. Installing the Cable
The DCS Series current sensors use a four pin Packard Sealed Metri-Pak 150 connector. You may either supply your
own or purchase a pre-made 12 inch pigtail from InPower, LLC (P/N: CA-DCS-12). Pin A is for +12V power, Pins B and
C output to the meter, and Pin D is for ground. See Mechanical Drawing below for further details.
4. Check Sensor & Meter Operation
Apply power to the sensor and verify that the meter is working correctly by checking battery charring and discharging
conditions. We recommend using a clamp-on ammeter, such as a Fluke, when verifying proper operation.
