Lightning Surge Protectors for

Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR

POTENTIOMETER USE

Functions & Features

• Designed specifically for potentiometer or

slidewire circuits

• Protects potentiometer transmitters from lightning surge

damage that enters on the wiring between the

potentiometer and the transmitter

• Absorbs surges only without affecting instrumentation

signal

• No interruption of signal by unplugging the protector

element
