Smart Voltage & Over-Current Air Conditioner Protector with Time Delay (For 1 Ton to 2 Ton AC)

Over-Voltage, Under-Voltage & Current Protection for Air Conditioners

Summer heat, grid voltage fluctuations, and sudden power cuts can burn out expensive inverter and non-inverter AC compressors. The Multilec OUP-6C Series is engineered to deliver continuous electrical protection for residential and commercial Air Conditioners. By constantly monitoring real-time voltage and current levels, it automatically disconnects power during unsafe conditions and safely restores it after line conditions stabilize.

Select the precise variation calibrated for your AC tonnage:

• Option A (1 Ton to 1.5 Ton): Optimized with an adjusted over-current trip setting for standard home AC units.

• Option B (2 Ton): Calibrated with a dedicated 12 Amps over-current trip limit to handle heavy starting currents and prevent motor/rotor locking on larger units.

Key Features & Highlights

• 🧠 Microcontroller Precision: Continuously tracks voltage and amperage, delivering instant cutoff during over-voltage, severe brownouts, or current spikes.

• ⚡ Over-Current Trip Defense: Prevents compressor motor burnout by tripping the power when current exceeds safe operating limits.

• ⏱️ Automatic Compressor Safety Delay: Features a built-in time delay before restoring power, allowing internal refrigerant pressure to equalize before the compressor restarts.

• 🔌 High-Capacity 20A Output Socket: Paired with a heavy-duty 15A power plug (or 3-core input cable) and a robust 20A socket to prevent loose sparking, terminal burning, and plug melting.

• 🛡️ Heavy-Duty Construction: Built with flame-retardant materials and high-grade electrical components engineered for tough environments.
