• The input tap is set by hand, so the winding in use always matches the supply of the country you are working in.
• Non-standard primary and secondary voltages can be wound to order.
• Output follows the selected direction: 110V/120V or 220V/240V.
• A good match for bench instruments, printers, water dispensers, fans and fax equipment.

■ 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.

■ FAQ

Is the DT-1000VA transformer the same as a 1000W travel converter?

No, and the difference matters when you size the load. The DT-1000VA transformer is a double-wound isolating unit rated in volt-amperes, whereas a “1000W” travel converter is usually a lightweight electronic device rated in watts at a much lower duty cycle. At 80% efficiency this frame carries about 800W continuously, and it holds that output on motor loads where a compact converter would sag.

Can I order a 220V to 110V converter 1000W as an ODM build?

Yes. Custom voltage combinations, alternative socket layouts, branded front panels and non-standard cable lengths are all produced to order, with a minimum of fifty pieces per specification. A 220V to 110V converter 1000W built to your own part number and packaging is a normal ODM request for us; lead time is 15–25 working days.

How to wire a step up transformer of this size?

Set the rotary selector to the voltage you actually measure at the wall, connect the input lead or terminate the primary into the terminal block, then energise with nothing connected and check the output socket with a meter. Add loads one at a time, heaviest first. If you are unsure how to wire a step up transformer into a fixed installation, bring the primary in through a lockable isolator so the unit can be taken out of service safely.

What will the 1000VA frame realistically run?

About 800W of resistive or electronic load, or 300–400W once the starting current of a motor is allowed for. Bench instruments, printers, kiosk terminals, small pumps and single power tools are all comfortable. Above roughly 800W of continuous load, move up to the 1500VA frame instead of running this one at its limit.

How is it packed for a first trial order?

Two units per carton at 49.5 × 33 × 21cm with foam inserts, and one or two pieces can be supplied as samples with a three to five working day lead time. A palletised 20ft container takes approximately 480 units at this carton size, and the 750VA and 1500VA frames share the same carton if you want to mix sizes.
