KEY

Overvoltage Protection and Longitudinal

Current Protection

The SLIC device, in conjunction with an external protection

bridge, will withstand high voltage lightning surges and

power line crosses.

High voltage surge conditions are as specified in Table 1.

The SLIC will withstand longitudinal currents up to a maxi-

mum or 40mARMS, 20mARMS per leg, without any perfor-

mance degradation.
