Product Description
The anti interference device can effectively suppress the instantaneous high voltage and high order harmonics which are caused by the switching on and off load, thus ensuring the reliable operation of the control system. Electrical designers know it has been increasingly being can be widely used in numerical control system and the PLC control circuit a series with electronic circuit of the electrical control system, its anti-interference ability is other devices can not be replaced, and has the features of low cost and good effect. A number of control systems manufacturers are clearly defined, the output interface where the inductive load, and then a group of anti interference devices as anti interference measures. My company according to the requirements of mechanical and electrical integration of products, reference the characteristics of similar products at home and abroad, combined with the specific reality of our country, developed a series of 3TX1 anti interference devices.
Products equipped with RC circuitandnot installed RC circuit productthe difference
no RC absorption unit
the current cataclysm occurs when the coil is OFF. Due to the coil inductance, a very high surge voltage will be generated, which will cause interference to the surrounding electronic equipment, thus causing misoperation or damage.
A RC absorption unit
the CR circuit (capacitor, electronic resistance series circuit) in parallel with the coil reduces the frequency of the surge voltage, thus inhibiting the sharp rise of the surge voltage (dv/dt characteristics). AC and DC circuits are reused.
Why need to install an arc extinguisher
(RC resistance-capacitor absorber)Because of the self-induction of the coil when using electronic equipment accessories, a reverse voltage of energy current will occur. In general, when a circuit contact is opened and closed, a voltage is generated at the contact, a current flows when the contact is closed, and a self-induced voltage occurs when it is opened. At the same time, a spark is generated, which forms an arc and generates high-frequency vibration, which will cause damage to the electronic circuit. The life of the contact is reduced due to the loss, deformation, increase in melting casting and surface acidification resistance, and poor contact caused by the spark at the contact. In order to prevent the occurrence of electric sparks, an accessory that can recover the circuit spark is inserted between the contacts. This accessory is an electric spark eliminator, an arc extinguisher, and an RC resistance-capacitor absorber.Features1. It has excellent adaptability and can absorb sharp pulse voltage.
2. Has excellent limiting voltage characteristics.
3. The power to absorb the surge is great.
4. Not only has the characteristics of symmetrical voltage and current, but also has the ability to capture positive / negative surges.
5. High rated power and high reliability.Range of applicationVarious machinery

Coils of contactors, solenoid valves, relays, etc. Differences between installed RC circuit and
non-installed RC circuit products
No RC absorption unit When the coil is turned OFF, the current changes rapidly. Due to the inductance of the coil, a high surge voltage will be generated, which will interfere with the surrounding electronic equipment, causing malfunction or damage. With RC absorption unit The RC circuit (capacitor, resistor series circuit) connected in parallel with the coil reduces the frequency of the surge voltage, thereby suppressing the sharp rise of the surge voltage (DV / DT characteristics). Reuse AC and DC circuits.
