DTK‑KG2 Kool Guard Intelligent Voltage Monitor & Surge Protector
The DITEK DTK‑KG2 provides advanced protection for HVAC systems by combining intelligent voltage monitoring with high‑capacity surge suppression. Designed for 120/240V or 120/208V split‑phase circuits up to 40A, the DTK‑KG2 automatically disconnects equipment during unsafe voltage conditions and restores power once levels normalize. A rugged UL Type 4X enclosure supports outdoor installation, while integrated diagnostics and auto‑calibration simplify setup and service. Ideal for inverter‑driven compressors, heat pumps, and mini‑split systems.
The DITEK DTK‑KG2 is a split‑phase intelligent voltage monitoring and surge protection device engineered specifically for HVAC systems, including inverter‑driven compressors and mini‑splits. It protects equipment from undervoltage, overvoltage, and transient surge events, automatically disconnecting power when unsafe conditions occur and restoring it once voltage stabilizes.
