Adapter & Power Supply

The AC adapter, AC/DC adapter or AC/DC converter is a type of external power supply, often enclosed in a case similar to an AC plug. Other names include plug pack, plug-in adapter. Adapters for battery-powered equipment may be described as chargers. AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power. The internal circuitry of an external power supply is very similar to the design that would be used for a built-in or internal supply.


We manufacture and supply AC DC Adaptors for Set Top Box(STB). These Adapters with AC/ DC Current are designed especially to meet the power requirement of Set Top Boxes. These Set Top Boxes are well tested on various parameter at our testing lab.

Range: 12V-500mA to 12V-5Amp.

  • Output Voltage: 12V
  • Output Current: 1.5 A

Potential Transformer

Potential transformers also called Voltage transformers (VT) are a parallel connected type of instrument transformer, used for metering and protection in high-voltage circuits or phase shift isolation. They are designed to present negligible load to the supply being measured and to have an accurate voltage ratio to enable accurate metering.
