    Description


    1. Support setting of device address (1 - 255) to enable cascading of multiple devices via RS485 bus
    2. Onboard voltage stabilizing chip, supporting a wide voltage range of 7V - 36V
    3. Onboard integrated power isolation, providing stable isolated voltage. The isolated terminals do not require additional power supply
    4. Onboard optocoupler isolation, capable of signal isolation, with high reliability and strong anti-interference
    5. Onboard self-recovery fuse and TVS (Transient Voltage Suppression Diode), effectively suppressing surge voltages and transient peak voltages in the circuit, preventing overcurrent, overvoltage, lightning and static electricity
    6. Onboard 0.002 ohm 1% sampling resistor, 16-bit high-precision acquisition, capable of measuring bidirectional current
    7. The maximum measurement voltage is supported up to 36V, the maximum measurement current is supported up to 8A, and direct measurement of power is supported
    8. Rail-mounted enclosure design, supporting stacking combination, easy installation, and safer to use
    9. Three external LED indicators, facilitating viewing of MCU status and signal transmission/reception status

    Must Read before ordering. Where trust drives commerce

    We believe in honesty over marketing.
    Some items may not have customer reviews yet, but the reviews you do see are 100% authentic, verified, and managed by Judge.me, an independent review partner trusted worldwide.

    Instead of posting fake reviews, we prefer to show only what is real — even if that means some products are still waiting for their first review.
