Key Features of the Single Phase Stabilizer
-
High‑Precision Voltage Regulation
-
Single Phase Automatic Voltage Stabilizer technology ensures output accuracy within ±3% of the nominal 220 VAC, even when input swings between 105–270 VAC.
-
Digital relay control for fast response (<1 s) and distortion‑free waveform guarantees stable output for AC units.
-
-
Robust Protection Functions
-
Over‑Voltage & Under‑Voltage Protection: Automatically disconnects output if input exceeds safe thresholds, then restores power after a built‑in time delay.
-
Surge & Spike Guarding: Protects connected equipment from transients and lightning‑induced surges.
-
Thermal & Short‑Circuit Protection: Automatic shutdown on overload or excessive internal temperature, ensuring equipment safety and stabilizer longevity.
-

- Commercial Spaces: Safeguard office wall‑mount ACs, server room cooling systems, and retail space climate control.
- Light‑Industry & Workshops: Ensure smooth operation of small‑scale industrial coolers and precision temperature control in electronics assembly.
FAQ
Q1: What makes the TKR Single Phase Stabilizer better than a conventional isolation transformer?
A1: Unlike passive isolation transformers, the TKR Electronic Automatic Voltage Stabilizer features active relay‑based regulation for fast, accurate voltage correction (within ±3%) and built‑in protections against over‑/under‑voltage, surges, and overloads. This ensures consistent performance and equipment safety in fluctuating power environments.
Q2: Can I customize the input/output voltage range for different regions?
A2: Yes. While standard units are configured for 105–270 VAC input → 220 VAC output, we offer OEM customization for input ranges (e.g., 90–260 VAC or 150–300 VAC) and output voltages (e.g., 110 VAC for North America). Minimum order quantities apply.
Q3: How do I choose the correct kVA rating for my air‑conditioning unit?
A3: Determine your AC’s starting and running current. Multiply the highest current (in amps) by your system voltage to get VA. Select a stabilizer with at least 20% higher kVA rating than this figure to accommodate startup surges comfortably. For example, a 4 A, 220 VAC AC needs ≈ 880 VA; choose a 1 kVA or higher model.
