Funciones

• Compact isolating transformer for equipment taken across a border and used on whatever voltage is available.
• The primary tap is chosen by hand, so one unit covers both 110V and 220V regions.
• Selector positions 110V – 120V – 220V – 240V, with other voltages available as a custom winding.
• Output taken from the socket at 110/120V or 220/240V, depending on direction.
• Field service teams use it for control systems, instruments, communications equipment and small industrial loads.

The DT/ST‑series travel voltage converter is a compact, isolated AC transformer designed for equipment and devices used across different voltage regions, especially in mobile, field, and temporary applications. Ranging from 100VA to 1500VA, these converters safely step down or step up AC mains voltage to match the rated input of control systems, test equipment, communication devices, and small industrial loads.

These travel voltage converters are ideal for industrial users, commercial facilities, electrical contractors, and field service teams that deploy equipment overseas or in regions with non‑standard grid voltages. Typical applications include control panels, HVAC controls, instrumentation, lighting systems, and temporary power setups, where stable, low‑noise AC conversion is critical.

JOHsunTECH is a professional manufacturer and factory of travel voltage converters, serving suppliers, distributors, wholesalers, and OEM/ODM partners worldwide. We support custom configurations, private labeling, low MOQ, and competitive wholesale pricing, enabling B2B buyers to build flexible, brand‑aligned product lines for industrial and commercial markets.

■ Cómo elegir este transformador

For portable duty the calculation is quick, but it still starts at the rating plate rather than the transformer. Add the input watts of the devices you will carry, apply 1.5 × for chargers, laptops and instruments, and 2.5–3 × for anything with a motor. The 100VA to 300VA sizes cover personal electronics, 500VA to 750VA suits small kitchen and personal-care appliances, and 1000VA to 1500VA is the band for test equipment and power tools.

Three things to settle before ordering:

• the highest appliance wattage you expect to run, plus its surge behaviour if it has a motor;
• the socket pattern that covers the countries you travel to most often;
• whether you need one socket on the body or two, since the layout changes the front panel.

■ Packaging for Travel Retail

Travel-channel packaging usually needs the input and output voltages visible on the front, a clear capacity figure and a compact instruction card. We print full-colour cartons against your artwork and supply instruction cards in the languages your market requires, with a minimum quantity of fifty pieces per specification. Field service and contractor buyers normally take the 1000VA and 1500VA sizes and skip retail packaging entirely.

■ Precios, pedidos y control de calidad

Rango de precios de los transformadores elevadores y reductores (100 VA–10 kVA)

Los precios de la serie DT/ST dependen de la capacidad, de la combinación de tensión de entrada y salida que necesites, del tipo de toma y de si lleva incorporado un selector de tensión o protección mediante un interruptor magnetotérmico (MCB). La tabla siguiente ofrece precios FOB orientativos para que puedas calcular tu presupuesto antes de solicitar un presupuesto en firme.

* Precio orientativo FOB Ningbo/Shanghái, configuración estándar, basado en 50 unidades por tamaño. No se trata de una oferta formal: el precio definitivo dependerá de la combinación de tensión, el estándar de enchufe, la carcasa y la cantidad del pedido.

1. El rendimiento de la serie DT/ST es de 80%. En el caso de equipos con motores o compresores, la corriente de arranque se multiplicará; por lo tanto, hay que prever siempre un margen de potencia adecuado.
2. Cargas puramente resistivas o electrónicas: elija un transformador con una capacidad ≥ 1,5 veces la potencia nominal del equipo.
3. Cargas inductivas, como motores y compresores: elija un transformador con una capacidad ≥ 2,5–3 veces la potencia nominal del equipo.
4. Esta tabla es meramente orientativa. Confirma la solución definitiva según la potencia nominal y el ciclo de trabajo que figuran en la placa de características de tu equipo.

■ Preguntas frecuentes

Is a transformer or a travel adapter the right choice?

A travel adapter only changes the shape of the plug; it does not change voltage. Where the appliance is rated for a different mains voltage than the one available, a transformer of this type is required.

Can I leave the selector on one setting for every country?

No. The tap has to match the local supply, and the switch must be moved with the unit de-energised. Marking the two most common settings on the body helps, but the selector still has to be checked before every trip.

Will a 500VA unit run a hair dryer?

Only if the dryer is rated below about 300W input. Most hair dryers draw 1,200W or more and would need the 1500VA frame. Check the rating plate rather than the product description.

Do these units work with 60Hz supplies?

Yes. The core is designed for 50/60Hz operation and the output frequency simply follows the input, so the same unit is suitable for North American and Latin American grids.
