SJW
Protect your appliances and equipment from dangerous voltage fluctuations. This Split Phase Automatic Voltage Stabilizer accepts a 110V – 0 – 110V (2×110V) input commonly found across South America and delivers a stable 220V output, safeguarding refrigerators, air conditioners, CNC machines, medical devices, and more. Built with a high-precision servo motor and copper-wound transformer for long-lasting, reliable performance.
Home – Refrigerators, air conditioners, washing machines, TVs, home theater systems
Small Business – POS terminals, computers, security systems, small workshops
Industrial / Workshop – CNC machines, laser cutters, 3D printers, packaging machines
Medical & Lab – Dental chairs, lab analyzers, imaging equipment
Telecom & IT – Servers, routers, UPS backup systems
In many South American countries — including Colombia, Venezuela, Ecuador, Brazil, Peru, and the Dominican Republic — the residential and light-commercial power supply uses a Split Phase (110V + 110V) configuration. Voltage sags, surges, and frequent fluctuations can severely damage sensitive electronics, shorten appliance lifespan, and cause costly downtime.
This automatic voltage stabilizer is engineered specifically for that environment. It continuously monitors the incoming Split Phase voltage and adjusts it in real time through a servo-motor-driven carbon brush mechanism, ensuring your equipment always receives a clean, steady 220 V supply.

Q1: What does "Split Phase 110V-0-110V" mean?
A: Your utility provides two 110 V "legs" (L1 and L2) with a neutral (N) in the middle. L1-to-N = 110 V, L2-to-N = 110 V, and L1-to-L2 = 220 V. This stabilizer accepts that configuration and outputs a regulated 220 V.
Q2: Can I use this with a 60 Hz supply?
A: Yes. The unit auto-detects 50 Hz or 60 Hz input and passes the same frequency through.
Q3: How do I choose the right kVA size?
A: Add up the wattage of all equipment you plan to connect, then multiply by 1.5 – 2× for a safety margin (especially for motor-driven loads like ACs and fridges). Example: a 2,000 W air conditioner → choose at least a 3–5 kVA stabilizer.
Q4: Does this unit work as a step-up transformer (110 V → 220 V)?
A: No. It is a voltage stabilizer, not a transformer. It requires a 220 V (110+110) input and keeps the output stable around 220 V. It will NOT create 220 V from a single 110 V line.
Q5: Is installation difficult?
A: The unit comes with a wall-mount bracket. You will need a qualified electrician to connect the Split Phase input wiring (L1, N, L2) and the 220 V output to your load. Always follow local electrical codes.
Q6: What warranty do you offer?
A: 2-year manufacturer warranty
Q7: Do you ship to Colombia / Brazil / Ecuador / …?
A: Yes, we ship across South America and worldwide. Shipping costs and delivery times are calculated at checkout.
