Kool Guard 2

Kool Guard 2 DTK-KG2 - is an intelligent voltage monitoring and surge protection device specifically engineered to safeguard mini-splits and inverter-driven HVAC systems from unstable electrical power.                                                                                                             Auto-Calibration: Detects electrical configurations automatically (120/240VAC or 120/208VAC split-phase circuits up to 40 Amps) without requiring manual fields programming.                                                                                                                                       Smart Disconnect: Cuts off power to the outdoor unit immediately if a voltage fault occurs, keeping it off for a 3-minute short-cycle delay to allow the power grid to stabilize.             Diagnostic Indicators: Features distinct red and green diagnostic LEDs that display real-time voltage status and system error codes.
