Description

Mutual inductance current monitoring, high current detection accuracy, stable performance, safe isolation of input and output.Magnetic hysteresis less than 1%, can be used in strong magnetic field conditions. The measured current AC: 0-10A / 20A / 50A can be selected.Output signal DC: 0-5V / 0-10V /4-20mA three forms are available. Installation and using are easy and convenient, there is no need to connect the dc series into the circuit during measurement.Through-heart structure design, isolation withstand voltage up to 2000V AC. The outer casing is made of self-extinguishing material, safe and durable.It is used for AC current monitoring, detection, current overload protection, and is also used as an electronic switch for automatic control systems. It is suitable for various applications requiring current and voltage conversion.It has the characteristics of strong overload ability, high precision, high isolation, high security, low power consumption and strong anti-interference ability. Description:
The FCS series AC current transducer provides real-time isolated measurement of AC current in the grid or circuit and converts it to a 0-5V/0-10V or 4-20mA DC current output signal. It can be mated with various AD and constitute various digital centralized acquisition systems. Or output to The PLC to form an automatic control system, or to match the traditional analog and digital indicating instruments, display the measured value.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $18 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for nodehawk products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
