Usage Tips:Item Type: 30A 6600W Soft Start Protection ModuleMaterial: PCBPower Supply Voltage Adaptation Range: AC 100V-250VCurrent: 30A (Maximum)Power: 6600W (Maximum)130A: This board uses oversized current (30A) pure copper foot relay and oversized thermistor NTC 10D 20 to effectively defend the machine from excessive starting current. 2AC 100V?250V: Power supply voltage adaptation range of AC 110V to 250V, small and fine, simple installation. 3Scope of Application: Start protection board is suitable for high end voice frequency power input, or other large start up current machine applications. Use suitable for power up to 6600W. 4Simple Operation: This board does not require an auxiliary power supply, only two terminals, one for power input (before you can connect a switch control), and one for output load, easy to use. 5PCB Material: Start protection board is made of PCB material, long time use without deformation, thus ensuring long term stability.1 x30A6600WSoftStartProtectionModule
