■ Cómo elegir este transformador

Five kilovolt-amperes is the point where a converter stops being carried and starts being installed, so the decision is less about wattage than about what the unit will feed. Work from the total connected load rather than the sum of nameplate ratings, allow for diversity in the real installation, and then check the heaviest motor separately. Air-conditioning and refrigeration compressors have the highest inrush of any common load and will dominate the calculation.

Three decisions to make in advance:

• whether the load is a single appliance or a small distribution board, which changes the downstream protection;
• the conversion direction and the socket standard for the destination market;
• where the unit will live, because 10cm of clear air on every side is a requirement rather than a recommendation.

■ Protecting the Downstream Circuit

When this frame feeds a sub-board rather than one appliance, design the protection alongside the transformer. Fit a dedicated breaker on the primary sized to the transformer, distribute the secondary through its own breakers, and add an earth-leakage device on that side if portable tools are involved. A lockable isolator upstream lets the unit be taken out of service without disturbing the rest of the installation. Because a laminated core produces both audible hum and continuous low-level heat, keep at least 300mm between the case and any heat-producing equipment.

Because the 3000VA, 4000VA and 5000VA frames share one carton at 54.5 × 33 × 24.5cm, a pallet can be mixed across three ratings without changing box dimensions — roughly 260 units fit a palletised 20ft container at this size.

Allow 300mm between the case and any heat-producing equipment in the same room, and avoid mounting it on a lightweight partition that would act as a sounding board. Both measures cut complaints about noise in occupied areas.

■ 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 DT-5000VA rated for?

The DT-5000VA is rated 5000VA continuous, single phase, at 50/60Hz with 80% conversion efficiency. It converts between 110–120VAC and 220–240VAC in either direction through the front-panel selector, carries fuse and MCB protection, and accepts either a cord and plug or a terminal-block input. It ships two units to a carton at 54.5 × 33 × 24.5cm.

When should I choose a 5kVA step down transformer rather than a 3kVA?

Choose a 5kVA step down transformer when the simultaneous load passes about 1,800W, or when a compressor or air-conditioning unit is involved. Practical limits on this frame are roughly 2,600W of resistive load, 1,600W of pump and fan duty and 800W of compressor load. Above those figures the transformer is no longer the constraint — the protection and cable sizing become the limiting factors.

Can the same unit serve as a 5kVA step up transformer?

Yes. The winding is bidirectional, so the same hardware acts as a 5kVA step up transformer when the input selector is set to the lower voltage and the load is connected to the higher tapping. That is why distributors can carry a single SKU per rating rather than stocking separate step-up and step-down products.

How should the secondary circuit be protected?

Fit a dedicated breaker on the primary sized to the transformer, then distribute the secondary through its own breakers. If portable tools will be connected, add an earth-leakage device on the secondary side. A lockable isolator upstream lets the transformer be taken out of service without disturbing the rest of the installation, which is what most site electricians ask for on a 5KVA build.

What are the packing and container figures?

Two units per export carton with foam inserts, and roughly 260 units in a palletised 20ft container at this carton size. Because the 3000VA, 4000VA and 5000VA frames share the same carton, a pallet can be mixed across three ratings without repacking. Wooden-crate packing is available on request for shipments where the carton alone is not considered sufficient.
