View of the device
During thunderstorms electronic devices are very vulnerable. Risk of over-voltage is present even in spots 1.5 km distant from the place where a lightning struck.
The LH Protector lowers the excess voltage to the safe level, according to European standards set for this type of equipment. It allows to avoid structural damage. The device does not need power supplying and does not interrupt data transmission.
Specifications
| Name | LH Protector |
| Code | J2820 |
| Maximum instantaneous current intensity of inter-wire surge (t=<1us) | Idmax= 350 A |
| Maximum long-lasting inter-wire current | Idconst= 1 A |
| Maximum instantaneous current intensity of ground surge (t=1us) | Igmax= 350 A |
| Maximum long-lasting ground leakage current | Igconst= 0.1 A |
| Inter-wire security actuation voltage | Vd= 3.0 V + / -10% |
| Ground security actuation voltage | Vg= 160 V + / -10% |
| Working temperature | 5-45 °C |
| Relative humidity | 10-80%, w/o condensation |
NOTE: If the protected line can suffer from over-voltages higher then the values above, preliminary security measures must be used.
Before beginning the installation, the electrical socket's grounding must function properly, and the protected device has to be correctly connected. If grounding fails the protector and network will not work rightly.
The right grounding
To avoid overvoltages the protector should not be connected to grounding with resistance larger than 4 ohm. The connection should be screwed down or soldered. USING LIGHTNING ARRESTER (OR GAS PIPE) AS THE GROUNDING IS ABSOLUTELY INADMISSIBLE!!!
The device protects only the equipment to which it is directly connected. Lack of grounding in one of the computers connected to a concentrator can result in appearing voltage causing the protector to react.
