Certification
What kind of environments is the surge protector suitable for?
The surge protective devices are rated for IP20 protection, making them suitable for indoor use in environments with low exposure to dust and moisture. They can operate in temperatures from -40°C to +85°C, ensuring performance in diverse conditions.
What is the response time of the surge protective device?
The SPD offers an extremely fast response time of ≤25ns, ensuring your DC systems are protected from instantaneous surges and that the devices respond almost immediately to any surge event.
What is the installation process for the surge protective device?
The surge protectors are designed for easy installation on a 35mm DIN rail and feature screw terminal wiring for conductors between 2.5–25mm², simplifying the connection process for both industrial and residential applications.
How do the surge protectors protect against lightning strikes?
The SPD has a lightning impulse current rating of up to 12.5kA for 10/350μs, which helps protect against lightning strikes and large surges, diverting harmful currents safely away from your electrical equipment.
What is the maximum voltage the SPD can handle?
The SPD can handle a maximum continuous operating voltage of 600Vdc to 1500Vdc, making it suitable for a wide range of solar power systems and other DC applications.
What is a Type 1+2 surge protective device?
A Type 1+2 SPD provides both direct lightning strike protection (Type 1) and protection from residual and induced surges (Type 2). The OMYH9 series is designed to protect photovoltaic systems and DC electrical systems from both types of surges.
