■ Cómo elegir este transformador

The number that decides the rating is starting current, not running watts. A compressor rated at 1/2 HP draws roughly 370W once it is up to speed, but can pull 1,800W for a moment on every start, and an air-conditioning unit behaves the same way. Build the calculation from input figures: list every load, mark which ones run together, total those watts, then multiply by the surge factor of the heaviest motor in the group. Above about 1,900W of calculated demand, this frame is no longer the right answer.

Check these three points before ordering:

• which way the conversion runs at your site — 110V to 220V or the reverse;
• the socket standard the destination market uses;
• whether the transformer will be switched at its own panel or from a wall isolator upstream.

■ Why a Double-Wound Core at 2KVA

At this power level the difference between an isolating transformer and a lightweight electronic converter becomes obvious in service. A double-wound core keeps primary and secondary physically separate, holds the output steady when a compressor starts, and limits harmonic distortion. Inexpensive autotransformer converters sag under the same load and shorten motor life. The DT-2000VA carries a full copper winding and a laminated core sized for continuous duty rather than for the first ten minutes of operation.

In workshop use we recommend leaving the input selector where it is and switching the unit at the wall instead. The selector is mechanical and does not need to be moved between jobs; leaving it untouched removes the most common user error, which is setting the wrong tap and under-powering the load.

Where several machines share the transformer, label each output with its input wattage. That removes the guesswork which leads to two heavy loads being started together and the MCB tripping.

■ 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

When do I need a 2kVA step up transformer instead of a 1kVA?

Move to a 2kVA step up transformer as soon as the simultaneous input wattage of your equipment passes about 800W, or as soon as a motor is involved. A 2KVA frame gives roughly 1,600W of continuous resistive capacity and can start small compressors that a 1kVA frame cannot. Sizing one step above the calculated load also keeps the winding cooler and the unit noticeably quieter.

Can you supply a 110V 220V voltage converter transformer as an ODM order?

Yes. A 110V 220V voltage converter transformer can be built with fixed or selectable primary tappings, any socket standard, custom enclosure colour and your own branding on the front panel and carton. ODM work starts at fifty pieces per specification, and we supply editable artwork templates so your designer can lay out the panel without a further tooling round.

Do you ship a China wholesale step up step down unit to distributors?

We do, and the 2KVA frame is one of the sizes most often ordered as a China wholesale step up step down unit because it is the largest rating that still ships two to a carton, which keeps freight cost per unit low. Mixed pallets combining the 2000VA, 3000VA and 5000VA ratings are straightforward, since all three share one carton size.

What are the starting-current limits on this frame?

Allow about 1,600W for resistive loads, 1,000W for pumps and fans, and 500–600W for compressors. Induction motors can pull five times their running current for a fraction of a second, so the nameplate figure on a motor tells you very little on its own. If your calculation lands near the boundary, choose the next frame up rather than relying on the tolerance of the winding.

Which output socket standards are available?

US two-pin and three-pin, UK, EU Schuko, Australian, South African and universal layouts are all produced, and a two-socket version is available on this frame. The socket is fitted during assembly rather than added afterwards, so it has to be specified at the time of order.
