Function

The HOS-100Q1 is a simple open-loop DC transducer capable of measuring DC currents in the range of ±100A. It is designed for applications where accurate current measurement is critical, such as power monitoring and energy management systems.

The VT406 / DC current transceiver bridges the measured data from the HOS-100Q1 transducer to the Vutlan monitoring system. This setup allows for real-time monitoring and analysis of current flow, ensuring that any irregularities in the system are detected early, which is crucial for the protection and stability of electrical systems.

The combination of these two components offers a reliable solution for integrating current measurements into Vutlan's comprehensive monitoring infrastructure.

Use cases

Here are additional use cases for the HOS-100Q1 DC current transducer and the VT406 DC current transceiver:

1. Renewable Energy Systems:

• Solar Power Monitoring: Used to track the current flowing between solar panels and batteries or inverters in photovoltaic systems. The HOS-100Q1 monitors the DC current from solar arrays, and the VT406 transfers the data to the monitoring system for performance analysis and fault detection.

• Wind Power Systems: In wind turbines, the DC current generated is monitored to ensure proper charging of storage systems or grid feedback, helping to maintain optimal system performance.

2. Electric Vehicle (EV) Charging Stations:

• Monitoring the DC current flow between the grid and electric vehicles during the charging process to ensure safe and efficient charging. Abnormalities can be detected, preventing overcharging or electrical faults in the charging system.

3. Battery Management Systems (BMS):

• Battery Discharge Monitoring: Measure the DC current to detect how much current is being drawn from batteries in backup power systems, such as uninterruptible power supplies (UPS), or electric vehicle batteries.

• Battery Charging Control: Ensuring that charging currents are within safe limits, optimizing the lifespan of the batteries and ensuring their reliability.

4. Data Centers:

• Power Monitoring: The combination of HOS-100Q1 and VT406 helps monitor the power consumption of critical infrastructure in data centers, particularly in high-density server environments. It ensures that power draw from servers, cooling systems, and other equipment stays within optimal limits.

5. Telecommunications:

• Power Backup Systems: In telecom facilities, where uninterrupted power is crucial, HOS-100Q1 can monitor the current flow from backup batteries to ensure proper performance during power outages, with VT406 transferring that data for remote monitoring.

6. Industrial Automation:

• Motor Current Monitoring: In automation and robotics, monitoring the DC current supplied to motors can help in predictive maintenance. The HOS-100Q1 ensures that motors operate within safe current ranges, while the VT406 helps integrate this data into a larger control system.

• Process Control Systems: The transducer can be used in manufacturing plants to monitor currents in machinery, ensuring they are operating efficiently without overloading.

7. HVAC Systems:

• Monitoring the power supply for heating, ventilation, and air conditioning systems in large commercial or industrial buildings. This ensures that the current load remains stable and identifies potential issues before equipment fails.

These use cases highlight the versatility of the HOS-100Q1 DC current transducer and the VT406 transceiver in monitoring, ensuring safe operations, and optimizing performance in various industries.

Technical specifications

Drawings & Dimensions

Components

The transducer consists of a plastic housing with an open/closed DC current loop and a 4-pin terminal connector. The current transceiver is a simple plastic case with 4 pins input, power 12V socket, and analog 0-5V RJ12 output.

Safety instructions

• Please observe the valid regulations for installation in the country in which the current transducer 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.

Siting location requirements

To ensure proper functionality, the conditions specified in the section “Technical specifications” must be observed.

Installation procedure

Notes on assembly

• Be careful, transducers max. voltage for isolation is 2kV.

• The transducer can measure DC current on any current wire, not more than 10 mm in diameter. Just open the cover, insert the wire, and close it.

• Max. maximum distance for the DC current transducer from the monitoring unit is 50 meters.

Installation

The transducer and the transceiver are installed together.

• Mount the transducer using M4 screws and M4 nuts. The distance between mounting holes is 50 mm.  

• Mount the current transceiver using M4 screws and M4 nuts. The distance between mounting holes is 60 mm.

• Use a 4-core flat cable and two green connectors supplied with the transceiver and the transducer to assemble the connecting cable.

Connection

Connect one end of the RJ11 / RJ12 cable to the monitoring unit and the other end to the analog output of the transceiver. Connect the transceiver to the power adapter 12V. Connect the transceiver and transducer with the Connecting cable. The monitoring system will automatically sense the current transducer as a 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.

1. Change the type of the sensor by choosing "Current". Choosing any type of sensor does not affect sensor properties, it only changes the sensor icons for the comfort of usage.
   
   

2. Change the name of the sensor, for example, "Current".

3. Use the "Expression formula", in the case of VT406 if the initial current is I=0 then output V=~2.5V, full scale is 5V, with use of sensor HOS-100 100A=5V and -100A=0V, that means B= -2.5V, K=40. Expr= 40*(x-2.5) or 40*x -100.

4. 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 a "Normal" state.

5. 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
