An external stabilizer protects your AC from:
- Low voltage damage
- High voltage spikes
- Power surges
- Compressor failure
This increases the lifespan of your air conditioner and prevents expensive repairs.
How to Choose the Best Stabilizer
1. Voltage Range
Choose stabilizers with wide voltage protection such as 130V – 300V.
2. Stabilizer Capacity
For a 1.5 ton AC, a 4 kVA stabilizer is recommended.
3. Safety Features
- High voltage cut-off
- Low voltage cut-off
- Thermal overload protection
- Time delay system
