This rugged control is FTM's 3rd generation power control. The AEC15 was built from the ground up using sophisticated Advanced Electronic Controller technology. Using a Digital Micro Processor allows the AEC15 to have OVERLOAD PROTECTION. If the controller senses an amperage overload, it will automatically limit the current flow to 15 amps and warn the operator with an indicator light. The controller also has a LOW VOLTAGE indicator light that warns you if your supply voltage drops below 100 volts. This power control has a rugged anodized aluminum housing with an internal cooling fan. The dual receptacle allows you to control 2 of FTM's Strip Heaters. Can be used with some NiChrome wire applications.
