ENTUBE DE-HB (100V 5V SESC)

ENTUBE DE-HB (100V 5V SESC) monitors are compact and plug-in-able current/voltage transducers, used for remotely monitoring a DC power supply.

It combines a high voltage galvanic isolation of 6000V plus AC ripple voltage measuring from 0.2Vac + 0,4Vpp up to 100V + 5Vss. The output is a 0-10V sine signal at a sampling rate of up to 200ms. It is possible to set various parameters such as sampling rates, shut off time, and delays.

Application field:ENTUBE DE-HB (100V 5V SESC) monitors are mainly used in renewable energy systems, primarily in photovoltaic applications. They can be used to readout the following parameters: charge and discharge current, voltage (for example, charging station voltage), power, voltage ripple, and temperature.

Working principle: The ENTUBE DE-HB (100V 5V SESC) current/voltage transducer works on the principle of galvanic isolation and capacitive current sensing. It has two input ports: one for highvoltage direct current and one for low-voltage alternating current. The device then uses capacitance to store the natural current by creating an electric field. It then detects the change in the electric field and transmits a signal to the external device.

The high-voltage side of the device is made up of two insulated leads, or galvanic isolators, which pass the AC or DC power between the two sides, only allowing a current that will allow the transducer to store the natural current. The low-voltage side has a diode bridge rectifier, which provides a steady voltage to the transducer.

When the electric field around the transducer changes, it produces a signal of 0-10V sine, which is amplified and converted to a digital signal by the controller board. The output can then be sent to the external device, such as a PC or PLC.

The transducer also has additional features, such as sample rate setting and shut off time for limiting the voltage, as well as supports other devices. As the device works on the principle of galvanic isolation, it provides a high degree of safety and accuracy.

In conclusion, the ENTUBE DE-HB (100V 5V SESC) current/voltage transducer is a compact and reliable device used for remotely monitoring DC power supplies, mainly used in PV applications. It has two input ports and provides a high degree of safety and accuracy. The device also supports additional features such as sample rate setting and shut off time.
