■ How to Choose This Transformer

Read the rating plate on the appliance before you look at the transformer. A device sold as “1000W” often draws more than its marketing figure, and anything with a motor or a compressor draws several times its running current for a fraction of a second on every start. Add up the input watts of everything that will be powered at the same time, then apply 1.5 × for heaters and electronics, 2.5–3 × for motors and pumps and up to 5 × for compressors.

Three details decide the exact specification:

• the supply voltage at the wall where the unit will be used, measured rather than assumed;
• the socket and plug standard of the destination market;
• whether the transformer will sit on a bench with a cord or be wired into a terminal block.

■ Where the 1000VA Frame Fits

One kilovolt-ampere is the smallest rating in the range that still drives a full workshop bench. Typical enquiries come from repair shops testing imported equipment, small production cells feeding a single machine, and retailers who want a compact converter that ships two to a carton and needs no installation work. If your calculation lands above 800W of resistive load, move up to the DT-1500VA step up and step down transformer.

Two ratio options are stocked most often: 220–240V down to 110–120V for imported appliances, and 110–120V up to 220–240V for equipment brought from North America into a 220V market. Both are the same unit with the selector moved, so a distributor needs only one SKU per rating.

The 1000VA frame is often specified with a universal socket in markets that use more than one plug pattern, because the appliance set on a bench changes more often than in a fixed installation.

■ 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.

1. 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.
2. Pure resistive / electronic loads: choose a transformer with capacity ≥ 1.5× the equipment rated power.
3. Inductive loads such as motors and compressors: choose a transformer with capacity ≥ 2.5–3× the equipment rated power.
4. This table is for reference only. Confirm the final solution according to the rated power and duty cycle shown on your equipment nameplate.
