Product Features:
combination type SPD
The smallest size single phase surge protector of Iimp: 25KA ;
only 27mm width, save space;
Sealed metal air gap technology,high energy electronic trigger
discharge gap, with the ability to block continuous flow
Low output residual;
fast response time (≤100ns);
lower voltage protection level ≤1.5kV
The combination type SPD characteristics:
1. lower residual pressure
can reduce the surge voltage above 6kV to less than 2 times of the
maximum working voltage of the system at one time, the three-phase
surge protector can reduce to 800V, and the single-phase can reduce
to less than 600V
2. Full protection and integration
The combination type SPD meets the protection requirements of
differential mode and common mode at the same time, and has the
protection between phase and line.
3, three layers of large current filtering efficiency
The design uses multi-layer high-current filtering function:the
first layer, a number of varistors and discharge tubes are
respectively arranged in matrix, and then connected in series to
meet the requirements of maximum flow; the second layer, the
varistor and discharge tube are respectively arranged in matrix to
strengthen and ensure the stability of flow capacity; The third
layer uses multiple varistors in parallel with transient diodes,
and then series, mainly used advantages of fast response time of
transient diodes
4. Short response time
The response time of composite surge protectors is generally less
than 5ns, and some are just 1ns.
5. Zero leakage current:
The combination type SPD adopts the discharge circuit of varistor,
gas discharge tube and transient diode combination. The ceramic
discharge tube plays a switch role in it, which effectively blocks
the leakage current of varistor, so its leakage current is zero.
6, over current, over temperature protection:
The combination type SPD is temperature and current control mode
circuit, block of overheating through the temperature fuse. When
the over current lead to the components of electrical surge
protector occur explosive or self-heating, can cut off the
connection electrical surge protector and power grid timely,
effective and quickly. Electronic temperature control is more than
10 times faster than mechanical response off.
7. Easy installation
The combination type SPD breaks through the limitations of the
traditional modular in the installation. It can be installed on the
35mm guide rail, also can be installed under various conditions and
in different directions.
