RFID LifeCheck SPD Test Devices
• SPD test device for preventive maintenance
– The RFID LifeCheck monitoring device detects thermal or electrical
overload conditions of all components
– To avoid imminent failure and thus system downtime, the protecti-
on module should be replaced as soon as possible
• Benefits of this type of SPD testing:
– Extremely easy and within a matter of seconds
– Detection of thermal or electrical pre-damage of all components
