NewTrend · DIN-rail DC energy monitoring
Product overview
The ODCM-63 is a DIN-rail mounted, four-in-one DC multi-function meter. Its colour LCD simultaneously displays DC voltage, current, power and accumulated energy. The instrument measures DC 14–600 V and up to 63 A, and is powered directly from the circuit being measured, without a separate auxiliary supply.
It is suitable for indoor solar-PV monitoring panels, battery systems and industrial DC circuits within the stated measuring ranges.

Display, energy memory and reset
The display keeps voltage, current, instantaneous power and energy visible together. Energy readings use an automatic decimal position as the accumulated value increases. On a power interruption the meter saves the accumulated energy, then resumes counting from that value when DC power returns. Press and hold RESET for five seconds to clear the accumulated energy.
DC input and load wiring
Connect the DC source to the upper IN terminals and the load to the lower OUT terminals. Positive (+) is on the left and negative (−) on the right in the front-view wiring diagram. Observe polarity, isolate the DC supply before connection and keep the circuit within the meter’s voltage and current ranges. This instrument is intended for DC measurement.
DIN-rail mounting and dimensions
The rear clip attaches to a 35 mm DIN rail. The dimension drawing shows a 54 mm width, 82 mm overall height and 66 mm depth. It also identifies a 45 mm front-body height and depth sections of 18 mm and 48 mm. Install indoors in a suitable panel, leaving space for the connected conductors.
Typical applications
- DC voltage, current, power and energy monitoring in solar-PV panels.
- Battery and energy-storage system monitoring within DC 14–600 V and 63 A.
- Indoor industrial DC power distribution and compatible DC equipment.
