    Overview

    An isolated DC ripple voltage transducer (also known as a DC voltage sensor) measures unidirectional ripple DC voltage and converts it into standard analog outputs while providing galvanic isolation between input, output, and power supply circuits for safe and reliable operation. The SUCH isolated DC voltage transducer supports a wide input range from 10mV to 1000V and outputs 0–5V, 0–10V, 0–20mA, or 4–20mA, enabling seamless integration with PLC, SCADA, and industrial control systems. It is widely used in DC power system monitoring, rectifier output verification, and battery ripple analysis across global industrial automation applications.

    Feature

    • DC 10mV to 1000V measurement range: Covers 14 selectable input ranges from low-level millivolt ripple signals up to high-voltage DC bus monitoring in a single unit.
    • 0–5V, 0–10V, 0–20mA, and 4–20mA output options: Compatible with most PLC, DAQ, and control system interfaces.
    • Input/output or 3-way isolation: Standard version isolates input from output; optional version extends isolation to the power supply. Isolation voltage rated at DC 2.5kV.
    • 0.2% F.S. accuracy: Stable measurements across the full input range with a temperature drift of 200Γ—10-6/Β°C.
    • DIN rail installation: Compatible with NS35/7.5, NS35/15, and EN50022 standards. Terminal block wiring for quick panel integration.
    • Industrial EMC protection: Surge immunity 2kV, ESD 6kV/8kV, and EFT burst 2kV.
    • Wide operating temperature: –25Β°C to +70Β°C, suitable for both indoor and industrial enclosure environments.
    • Durable housing: Fire-retardant ABS enclosure, IP20, MTBF over 50,000 hours.

    FAQ
     ❯

    The standard version isolates input from output, with the output terminals providing the power supply β€” suitable for most applications where input voltage is ≀600V. The 3-way isolation version extends isolation to the power supply circuit as well, recommended when input voltage exceeds 600V or when the power supply circuit requires additional protection.

     ❯

    Yes. With 14 selectable input ranges spanning DC 10mV to 1000V, a single unit covers both low-level ripple signal detection and high-voltage DC bus monitoring, removing the need for separate devices.

     ❯

    It depends on the input interface. The 0–5V and 0–10V voltage outputs require DC 24V power supply. The 0–20mA and 4–20mA current outputs work with both DC 12V and 24V, and are generally preferred for long-distance signal transmission as current signals are less susceptible to line interference.

    isolated dc ripple voltage transducer works well for dc systems
    picked up an isolated dc ripple voltage transducer for a battery charger evaluation project. setup didn’t take much time, mainly needed basic calibration and output verification. the isolated dc ripple voltage transducer gives clear feedback on ripple changes and stays stable during continuous measurement. had to adjust scaling in the controller, but overall it fits my application well.
