Походные преобразователи напряжения серии DT/ST - это компактные изолированные трансформаторы переменного тока, предназначенные для оборудования и устройств, используемых в различных регионах напряжения, особенно в мобильных, полевых и временных приложениях. Эти преобразователи мощностью от 100 до 1500 ВА безопасно понижают или повышают напряжение сети переменного тока для соответствия номинальному входному напряжению систем управления, испытательного оборудования, устройств связи и небольших промышленных нагрузок.
Эти преобразователи напряжения для путешествий идеально подходят для промышленных пользователей, коммерческих объектов, подрядчиков по электромонтажу и сервисных бригад, которые размещают оборудование за рубежом или в регионах с нестандартным напряжением сети. Типичные области применения включают панели управления, системы управления ОВКВ, КИПиА, системы освещения и временные источники питания, где стабильное и малошумное преобразование переменного тока имеет решающее значение.
JOHsunTECH является профессиональным производителем и фабрикой преобразователей напряжения, обслуживающей поставщиков, дистрибьюторов, оптовиков и OEM/ODM партнеров по всему миру. Мы поддерживаем индивидуальные конфигурации, частную маркировку, низкое MOQ и конкурентоспособные оптовые цены, позволяя покупателям B2B создавать гибкие, согласованные с брендом линейки продуктов для промышленных и коммерческих рынков.
■ How to Choose This Transformer
For portable duty the calculation is quick, but it still starts at the rating plate rather than the transformer. Add the input watts of the devices you will carry, apply 1.5 × for chargers, laptops and instruments, and 2.5–3 × for anything with a motor. The 100VA to 300VA sizes cover personal electronics, 500VA to 750VA suits small kitchen and personal-care appliances, and 1000VA to 1500VA is the band for test equipment and power tools.
Three things to settle before ordering:
- the highest appliance wattage you expect to run, plus its surge behaviour if it has a motor;
- the socket pattern that covers the countries you travel to most often;
- whether you need one socket on the body or two, since the layout changes the front panel.
■ Packaging for Travel Retail
Travel-channel packaging usually needs the input and output voltages visible on the front, a clear capacity figure and a compact instruction card. We print full-colour cartons against your artwork and supply instruction cards in the languages your market requires, with a minimum quantity of fifty pieces per specification. Field service and contractor buyers normally take the 1000VA and 1500VA sizes and skip retail packaging entirely.
■ 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
Is a transformer or a travel adapter the right choice?
A travel adapter only changes the shape of the plug; it does not change voltage. Where the appliance is rated for a different mains voltage than the one available, a transformer of this type is required.
Can I leave the selector on one setting for every country?
No. The tap has to match the local supply, and the switch must be moved with the unit de-energised. Marking the two most common settings on the body helps, but the selector still has to be checked before every trip.
Will a 500VA unit run a hair dryer?
Only if the dryer is rated below about 300W input. Most hair dryers draw 1,200W or more and would need the 1500VA frame. Check the rating plate rather than the product description.
Do these units work with 60Hz supplies?
Yes. The core is designed for 50/60Hz operation and the output frequency simply follows the input, so the same unit is suitable for North American and Latin American grids.
