Surgenon QN420/QN421 series, an induction surge preventer that protects all equipment from induced lightning surges
Hosansho Co., Ltd.
About This Product
Preventing power supply and communication equipment in OA/FA from induced lightning surges
Features
■Free connection to public telephone circuits
After confirmation by the construction supervisor, all you have to do is connect the telephone line and plug in the power plug.
■Grounding (earth)
When grounding is required, use the ground terminal.
■Does not distort the signal waveform
Since the capacitance is 1pF and the insulation resistance value is over 100MΩ, it will not affect the digital signal on the communication line.
■No risk of short circuit
When an excessive surge enters, the element becomes OPEN and there is no risk of short circuit.
■LED display of surge
Just like QN430, the LED lights up when it absorbs abnormal voltage caused by induced lightning. The surge absorption function continues even if it is lit.
