■ How to Choose This Transformer
Start from the equipment nameplate rather than from the transformer. Add the input watts of everything that will run at the same time, then apply a factor of 1.5 for heating and electronic loads, 2.5–3 for motors and pumps, and up to 5 for compressors and refrigeration. If the total falls between roughly 1,200W and 1,800W of resistive load, the DT-3000VA is the right frame.
Before ordering, confirm three practical points:
- the mains voltage where the unit will be used;
- the plug and socket standard for your market;
- whether the transformer will run from a cord or be hardwired into a terminal block.
■ Pricing, Ordering & Quality Assurance
Step Up & Step Down Transformer Price Range (100VA–10KVA)
Pricing for the DT/ST series depends on capacity, the input/output voltage combination you need, socket type, and whether a voltage selector or MCB protection is fitted. The table below gives indicative FOB levels so you can budget before requesting a firm quotation.

* Indicative FOB Ningbo/Shanghai, standard configuration, based on 50 pcs per size. Not a formal offer — final price depends on your voltage combination, socket standard, enclosure and order quantity.
- The efficiency of the DT/ST series is 80%. For equipment with motors or compressors, the starting current will multiply — always reserve adequate power margin.
- Pure resistive / electronic loads: choose a transformer with capacity ≥ 1.5× the equipment rated power.
- Inductive loads such as motors and compressors: choose a transformer with capacity ≥ 2.5–3× the equipment rated power.
- This table is for reference only. Confirm the final solution according to the rated power and duty cycle shown on your equipment nameplate.

■ FAQ
What is the difference between the DT and ST models?
Electrically they are the same double-wound transformer. DT units are catalogued for step-up duty (110V to 220V) and ST units for step-down duty (220V to 110V); both directions are available on either model through the input voltage selector.
Which rating do I need for a 1.5kW appliance?
1,500W of resistive load suits a 2KVA frame or larger. If the appliance has a motor or compressor, apply the surge factor first — a 1,500W compressor would call for a 5KVA frame or above.
Can the output socket be matched to my market?
Yes. US, UK, EU, Australian, South African and universal layouts are all produced. Specify the standard when ordering, as it is fitted during assembly rather than added afterwards.
Is a carrying handle supplied?
Yes, on every DT/ST unit up to 5KVA. From 7.5KVA upward the enclosure is intended for fixed installation.
