## Summary description

Voltage transformer extra digital NV823086 converts between 110 VAC and 220 VAC and supports up to 500 W. Designed for step-up and step-down voltage conversion, it allows using appliances rated for the other mains standard. Suitable for small household electronics, lamps, chargers and some power tools within the 500 W limit; provides a practical solution for travel, relocation or equipment compatibility.

## Long description

The extra digital NV823086 voltage transformer converts between 110 VAC and 220 VAC and supports a continuous rated power of up to 500 W. It is a bidirectional step-up/step-down transformer with toroidal winding construction and single-phase operation, intended to provide the correct output voltage for compatible small household electronics, lamps, chargers and other devices when mains voltage and appliance voltage differ. The unit includes overload and short-circuit protection, carrying handles and complies with ISO9001 and CE quality marks. Dimensions are 127 x 85 x 101 mm and the product is covered by a 24-month warranty.
Advantages
The transformer provides reliable bidirectional conversion (110 VAC ↔ 220 VAC) and stable output at 50/60 Hz suitable for devices designed for either mains standard. Toroidal winding reduces electromagnetic interference and improves thermal performance in a compact housing. Built-in overload and short-circuit protection increase safety when used within the rated 500 W capacity, while carrying handles make transport and positioning easier. Certification to ISO9001 and CE shows conformity with common quality and safety requirements.
Suitable for
Small household electronics such as radios, chargers and small kitchen appliances within 500 W
Lamps and lighting equipment compatible with the transformer’s output
Portable devices and travel equipment when relocating between 110 V and 220 V regions
Workshop tools and low-power power tools that do not exceed the 500 W rating

How to use
Place the transformer on a stable, ventilated surface and ensure the device and transformer are switched off before connecting. Verify the local mains voltage and connect the transformer input to the corresponding supply (110 V or 220 V). Connect the appliance to the transformer output that matches the appliance rated voltage. Turn on the transformer first if the appliance manufacturer recommends powering the converter before the device, then switch on the appliance. Do not exceed the 500 W rated power; observe device start-up current which can be higher than running current. If the protection trips, disconnect the appliance and transformer, check for overload or short-circuit conditions and allow the unit to cool before attempting to reuse.
Usage recommendations
Use the transformer only with appliances whose running power stays below 500 W. For devices with high inrush current (motors, compressors, some power tools) verify the start-up current and consider a transformer with higher power rating if necessary. Keep the transformer in a dry, well-ventilated area, avoid covering it during operation and allow sufficient clearance for heat dissipation. Follow the appliance manufacturer’s instructions and applicable safety standards when using voltage conversion equipment.
