2kVA Wall Mount Automatic Voltage Regulator

The AVS 2KVA Wall Mount Automatic Voltage Regulator is built with the audiophile and home cinema enthusiast in mind. Its toroidal transformer generates significantly less magnetic stray field and mechanical hum than traditional EI types, making it ideal for noise-sensitive environments. The advanced MCU uses zero-cross switching to avoid generating transients that could be heard as clicks in speakers.

The regulator’s 7-tap relay system ensures that output voltage remains stable even when mains power fluctuates, preventing screen flicker, audio distortion, and premature component ageing. The unit’s sleek white casing and compact wall-mount dimensions (380×308×160 mm) blend well with modern interior designs.

Core Advantages

1. Low-Noise, Low-EMI Toroidal Transformer

The toroidal design minimises audible hum and electromagnetic interference – crucial for preserving the signal-to-noise ratio in home theatre and audio systems. You’ll enjoy cleaner sound and sharper video.

2. Precise Regulation for Sensitive Components

Maintaining ±8% accuracy protects power supplies of AV receivers and gaming consoles, preventing overheating and extending their operational life. It also stabilises brightness and contrast on large LED/OLED TVs.

3. Overload and Over-Temperature Safeguards

With a 120% overload cut-off and a 120°C thermal sensor in the transformer coil, the AVS-2000P automatically shuts down under fault conditions, protecting your expensive equipment from damage.

4. Professional Wall-Mount Aesthetics

The regulator comes with wall-mounting hardware, allowing you to install it behind the TV or on a side wall, keeping cables organised and out of sight.

FAQ

1. Does the AVS 2KVA Wall Mount Automatic Voltage Regulator produce any audible hum?

The toroidal transformer is inherently quiet. Under normal load, any hum is barely perceptible – well below 30dB.

2. Can I connect a subwoofer amplifier?

Yes, as long as the total load stays within 1200W. Subwoofers often have high peak demands; the regulator can handle short surges.

3. Is there a surge protection feature?

The unit provides basic surge suppression via its fast-acting relay and cut-off circuits. For extreme lightning, we recommend adding an external SPD.

4. Why is low EMI important for audio and video equipment?

Electromagnetic interference (EMI) from power transformers can couple into audio signal paths and video cables, causing audible hum, reduced soundstage clarity, and subtle video artifacts such as horizontal bars or colour shifting. The AVS-2000P uses a toroidal transformer with a closed magnetic field geometry, which radiates significantly less stray flux than traditional EI-type transformers. This preserves the signal-to-noise ratio of your audio system and ensures clean video output, particularly important for high-resolution formats like 4K HDR and high-fidelity audio.

5. Will the AVS-2000P affect the sound quality of my amplifier?

The AVS-2000P does not process or amplify the audio signal, so it will not add colouration or distortion to the sound. Instead, it ensures that your amplifier receives a stable, regulated AC voltage. This prevents the amplifier's internal power supply from working harder than necessary during voltage sags, which can introduce thermal noise and reduce dynamic headroom. The low-EMI transformer also reduces the chance of hum coupling into sensitive pre-amplifier stages.

6. Can I connect a projector and an AV receiver to the same regulator?

Yes. A typical 4K projector consumes 200‑350W, and a mid-range AV receiver consumes 300‑500W, totalling 500‑850W. This is well within the AVS-2000P's 1200W rated capacity, with ample headroom for both devices. Always check the nameplate power ratings of your specific models and sum the total running power to ensure it does not exceed 1200W.

7. What does the yellow LED indicate during normal operation?

The yellow LED illuminates during the start-up delay period after the unit is powered on or after a power outage. During this delay (6 seconds or 180 seconds, depending on your setting), the regulator is monitoring the input voltage and preparing to engage the relay network. The yellow LED turns off and the green LED turns on once the delay period ends and the unit begins delivering regulated output power.

8. Can the AVS-2000P be used with a power conditioner or audiophile-grade power strip?

Yes. The AVS-2000P is compatible with most power conditioners and audio-grade distribution boards. In fact, using the AVS-2000P upstream of a power conditioner provides an additional layer of voltage stabilisation, allowing the conditioner to focus on filtering high-frequency noise rather than compensating for voltage sags. This combination can enhance overall system performance.
