What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• For automatic switching between normal and standby power supplies.
• Relay the work voltage range from 120v to 280v,
it can still work,not appear coil burned phenomenon.
• Small size, with firefighting, power generation and other functions.
• Strong anti-interference ability Quick Transfer reliable performance.
