MDP-SP
Lightning Surge Protectors for
Electronics Equipment M-RESTER
LIGHTNING SURGE PROTECTOR FOR
LOW FREQUENCY USE
Functions & Features
• Designed specifically to protect frequency generating devices such like flowmeters and frequency transmitters from lightning surge damage that enters on the wiring between these instruments
• Absorbs surges only without affecting instrumentation signal
• No interruption of signal by unplugging the protector element
