2200Pf~0.1μF；To reduce leakage current, capacitance is no more than 0.1 μ F, and capacitor midpoint should be connected with the earth；C1~C3
Pressure voltage be 400VAC；Common mode inductance uses the internal circuit of two-stage combined type electromagnetic interface filter, due to using two-stage (also
Claim two sections) filtering, therefore filter out the better effect of noise.For certain user scene there are repetition rate be several kHz it is fast
The problem of fast transient state burst of pulses interferes, also develops burst of pulses filter (also known as burst of pulses confrontation device) both at home and abroad, can be to above-mentioned
Inhibiting effect is played in interference.
Further, the lightning-protection module is KS-LMP01 module.
Further, in the socket, power supply line successively through overcurrent protective device, lightning-protection module, filter module and is led
Electric unit connection.
Further, the lightning-protection module and filter module are connected with LED display module or LED warning lamp, and LED shows mould
Block or LED warning lamp are mounted on socket outer surface.
Further, the socket is band protection 5 spring hole scoket of gate national standard, and is made using heat-resistant fireproof material.
Compared with prior art, the present invention has the advantage that
1, electrical security meets concerned countries standard, for protecting the national classified information of confidential and its following level of confidentiality, is
Prevent the preferred product emitted by power supply line electromagnetic exposure, socket part uses heat-resistant fireproof material, prevent power supply line it
Between cross-inductive coupling and electromagnetic leakage, while being integrated in overload protection and antisurge defencive function in integrated design.
2, other than in addition to having the function of common converter (power supply expansion is flexibly and easily the power supply of multi-section equipment),
Due to using filtering shield technology, it can make to export outside more stable, can more play and inhibit connected information equipment power supply line
The effect of conducts information leakage minimizes the leakage for entering general supply network transmitting.
3, in current overload, overcurrent protective device can cut off the power rapidly, after excluding overload, can restore normally to protect automatically
Shield state.
4, when encountering thunder and lightning and surge pulse, the equipment that is connected on socket is protected by lightning-protection module, avoid due to
Surge pulse caused by lightning stroke, large-scale inductive load facility switching, static discharge and failure is injured caused by equipment.
