Couldn't load pickup availability
The AC Varistor In-Line Adapter Board is an essential plug-and-play adapter board that allows varistors to be mounted easily and securely across AC lines and from AC lines to Earth.
Not only is it perfect for trying out different parts during pre-compliance, but its secure connections and plastic case mean it can be permanently installed in any equipment or product.
The adapter board can easily be incorporated into existing systems using the lever arm screwless terminal blocks. Varistors can be placed across the lines by simply pushing them into the varistor blocks in the centre of the board. The AC Varistor In-Line Adapter Board can easily be added to you products' BoM to fix your EMC issues without the hassle of having to redesign!
Features
- Plug & play varistor adapter board
- Designed for use in AC applications (240V)
- Insulated plastic case means metallic parts cannot be touched
- 0°C to +70°C operating temperature range
Frequently Asked Questions
How does a varistor work?
Varistors have a variable resistance dependent on the voltage applied. The higher the voltage the lower the resistance so when there is a increase voltage surge on the line (e.g. ESD, surge or transient) the voltage diverts through the varistor rather than damaging your product electronics.
Is a varistor single use?
No
A varistor can see multiple high voltages or ESD surges and recover. However, the varistor will get damaged if there is a prolonged high voltage applied (higher than its rating).
Where do I place a varistor?
The varistor should typically be fitted between the positive and neagtive lines in a DC system and between line and neutral, line and Earth and neutral and Earth in and AC system. Varistors should be place on any lines that may be susceptible to voltage fluctuations.
