MDP-JS

Lightning Surge Protectors for
Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR
SELF-SYNCH USE

Functions & Features
• Designed specifically for self-synchronizing motor circuit
• Protects self-synch transmitter and converter from damage caused by surges on the wiring
• Absorbs surges only without affecting instrumentation signal
• No interruption of signal by unplugging the protector element
