The iSPD (Intelligent Surge Protection Device) offers comprehensive protection for your HVAC equipment.

The MARS 83907 Surge Protection Device is designed to provide maximum compressor protection from harmful power surges, transients and over- voltages utilizing the latest Thermally Protected MOV technology.

In addition, the modules microprocessor technology monitors line voltage to protect the compressor from starting or running during “brown outs” and low line voltage. The module also monitors refrigerant temperatures to identify coil freeze-up and or low refrigerant issues.

If the module detects a low voltage or refrigerant issue the compressor is shut down. The module will automatically reset when specified operating parameters are restored and determined to be stable.

In the event of diminished surge protection or failure, the compressor will not be allowed to start until the module is replaced.
