■ Cómo elegir este transformador

Two kilovolt-amperes is the rating to pick when several appliances have to be available on one circuit rather than used one at a time. Total the input wattage of everything that could be plugged in simultaneously, then apply the surge factor for the worst load in the group — 1.5 × for resistive and electronic equipment, 2.5–3 × for motors, and up to 5 × for a compressor. This frame supports roughly 1,600W of continuous resistive load, which is two medium appliances at once.

Three points to settle first:

• which appliances will share the transformer, and whether they can ever run together;
• the plug and socket standard used in the destination market;
• where the unit will sit, because a cabinet or cupboard will trap the heat it produces.

■ Running It in a Hospitality Setting

In hotels, guesthouses and staff canteens the transformer usually stays connected while staff plug different devices into it through the day. Under that pattern the requirement is thermal headroom rather than peak capacity, and the ST-2000VA carries about 1,600W continuously. Mark which sockets are fed by the transformer so nobody adds a fourth appliance, and check that the unit itself has ventilated space rather than being tucked inside a service cupboard. Fuses are standard items available locally; there is nothing to calibrate and no consumable parts.

There is very little to maintain: inspect the fuse annually, keep the ventilation slots clear of dust and confirm the input selector has not been moved. Terminations inside the case should be checked for tightness every two years in commercial installations. No lubrication, calibration or consumable parts are involved.

■ 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

What is the difference between the ST-2000VA and the STU models?

They share the same core and enclosure. The ST-2000VA is catalogued as a straightforward single-phase step-down converter, while the STU models are the same platform marketed with the USB outlet and travel accessories. If you do not need the USB port, the ST version is the simpler buy.

Can a fridge and a microwave share this transformer?

Not at the same time. The fridge draws little once running, but its compressor start-up is heavy, and a microwave pulls 1,300–1,600W from the wall while it cooks. Add the input wattages first, remembering that 2KVA leaves about 1,600W of continuous capacity.

Which socket standard should I specify?

Match the appliances, not the building. If the 110V equipment came from the United States, order a US socket; where a market stocks mixed appliances, a universal socket avoids returns. The standard is fitted during assembly, so it cannot be changed afterwards.

Does the enclosure need to be earthed?

Yes. Bond the case to the installation earth and connect the transformer to a socket that is itself protected by an earth-leakage device. The output is isolated from the primary, which is a safety benefit, but the enclosure is metal and still needs earthing.

What happens if I exceed the rating?

The MCB protects against short circuits and gross overload, not against sustained overloading. Running above the continuous figure shows up as heat first and shorter service life later, so choose one frame up if your load sits close to the limit.
