Function
Simple Bidirectional DC Ammeter VT416 can measure DC currents in the range of ± 6A.
Key Highlights:
● Measures DC current in both directions (± 6 A typical) for versatile monitoring of power systems.
● High accuracy: approx. 1 % measurement error ensures reliable readings.
● Outputs a 0–5 V signal corresponding to current flow, making it easy to integrate into existing monitoring systems.
● Galvanic isolation up to 2.5 kV protects your sensor and system—even in demanding environments.
Models
Model | Measured DC current range | Notes |
|---|---|---|
VT416-6A | ± 6A | Default |
VT416-15A | ± 15A | custom order |
VT416-25A | ± 25A | custom order |
Use cases
● Telecom & Data Centers
– Monitoring DC current in rectifier racks, battery banks, and DC distribution lines.
– Detecting overloads or faults in backup power systems.
● Industrial Automation
– Measuring DC current in PLCs, motors, and production lines.
– Tracking energy consumption of DC-powered machinery.
● Renewable Energy Systems
– Solar installations: monitoring current from PV panels to charge controllers or batteries.
– Wind or hybrid micro grids: ensuring proper current flow and early detection of anomalies.
● Battery Storage & UPS Systems
– Monitoring charging/discharging current in lead-acid, Li-ion, or VRLA battery banks.

Safety instructions
Please observe the valid regulations for installation in the country in which current monitor is installed and operated, and the national regulations for accident prevention. Please also observe any internal company regulations, such as work, operating and safety regulations.
The technical specifications and limit values stated must not be exceeded under any circumstances. In particular, this applies to the specified ambient temperature range and IP protection category.
Installation procedure
Notes on assembly
Be careful, sensor max. The voltage for isolation is 2kV.
Inputs on both poles are parallel.
The monitor can measure DC current on any current wire, not more than 3 mm in diameter.
Max. distance for DC current transducer from the monitoring unit is 50 meters.
Installation
Mount the current monitor using self-adhesive feet or stickers.
Connect current wires to terminals.
Configuration
Connect one end of the RJ11 cable to the monitoring unit and the other RJ9 end to the analog output of the current monitor. The monitoring system will automatically sense DC current monitor as an fV sensor.
The new sensor will appear in the web interface of the system. Click on the "System tree" menu and you will find a new sensor marked by an icon (abbreviation from: Voltage function, used for sensor monitors and converters). Click on the sensor to open its properties.
A modal window with sensor properties will pop up.
Change the type of the sensor by choosing "Current". Choosing any type of sensor does not affect sensor properties, it only changes the sensor icon for the comfort of usage.
Change the name of the sensor, for example, "Current".
Use "Expression formula", for VT416 if initial current I=0 then output V=~2.5V, that means B= ~-2.5; full scale is 5V, 8A=5V and -8A=0V, that means K=3.25. Expression = 3.25*(x-2.5). Please calculate "B" accurately with zero current.
Put in the threshold levels by dragging: Low alarm, Low warning, High warning, High alarm levels.
For example, the graph above shows that the state of the sensor at the moment is "Normal" because 20.4 is between "Low warning" and "High warning" states, which is considered the "Normal" state.Click “Save” or “Apply” at the bottom of the “Properties” window. The page will reload, and the sensor will update by changing its icon type to
(an abbreviation from: "Ampers").
Mounting
a) Wall mounting can be achieved by using the stickers supplied in the package.
b) Or you can use adhesive legs to put it on a surface.
