Field
Equipment
(4-20 mA loops)
The
Surge Control line of field equipment protectors are ideally suited
for harsh environments. They are designed to protect equipment from
the destructive effects of lightning strikes, electrical disturbances,
surges and spikes. In addition, EMI/RFI filtering will reduce damaging
electrical noise from reaching sensitive equipment. These models are
multi-stage, hybrid devices that feature both common and differential
mode suppression.
Features:
- Effective EMI/RFI Filtering
- Designs exceed UL, CSA, IEC, ANSI/IEEE and FM recommendations
- Various operating voltages
- Sub nanosecond response time
- Automatic reset, requires no maintenance
