What Is a Stabilized Power Supply?
A stabilized power supply is an essential electrical device designed to maintain a consistent output voltage regardless of fluctuations in input voltage. Especially in areas prone to unstable electrical grids or sudden voltage drops, this type of power regulator ensures that connected appliances operate safely and efficiently. The TMB Series offers a compact, single-phase solution for residential, office, or light industrial applications.

How TMB Compares to Other Stabilized Power Supplies
| Caratteristica | TMB Series | Conventional Regulators |
|---|---|---|
| Wide input voltage range | ✔ Customizable | ✘ Limited range |
| Display digitale | ✔ Real-time readings | ✘ Analog or none |
| Multiple protections | ✔ Built-in | ✘ Basic protection only |
| Installation options | ✔ Wall-mounted/Vertical | ✘ Fixed only |
| Control mechanism | ✔ Relay type | ✔ But often outdated design |
Choosing the Right TMB Power Supply
To ensure optimal performance, select a model based on your equipment’s total power consumption and expected voltage fluctuation severity. Here’s a general guide:
- TMB-1000VA to 3000VA: Ideal for routers, TVs, small refrigerators, or computers.
- TMB-5000VA to 10000VA: Suitable for air conditioners, washing machines, and home office setups.
- TMB-15KVA to 30KVA: Best for villas, small workshops, or multi-device installations.
Always add 20-30% buffer to your actual load to account for start-up surges.
FAQ
Q1: Can I use the TMB stabilized power supply with a refrigerator or air conditioner?
A: Yes. Models 2000VA and above are suitable for appliances with motors, including refrigerators, air conditioners, and washing machines. Always check the appliance’s rated and starting power before choosing.
Q2: What happens if the voltage goes below 45V or above 260V?
A: The TMB stabilizer is equipped with protection circuits. If the input voltage falls outside the regulated range, the unit will safely disconnect the output to protect your devices.
Q3: Is the delay function important?
A: Absolutely. The delay time (6s/180s) allows voltage levels to stabilize before connecting the load, particularly important for compressors and sensitive electronics.
