الوظائف

• Compact isolating transformer for equipment taken across a border and used on whatever voltage is available.
• The primary tap is chosen by hand, so one unit covers both 110V and 220V regions.
• Selector positions 110V – 120V – 220V – 240V, with other voltages available as a custom winding.
• Output taken from the socket at 110/120V or 220/240V, depending on direction.
• Field service teams use it for control systems, instruments, communications equipment and small industrial loads.

إن محول الجهد المتنقل من سلسلة DT/ST عبارة عن محول تيار متردد معزول مدمج مصمم للمعدات والأجهزة المستخدمة في مناطق الجهد المختلفة، خاصة في التطبيقات المتنقلة والميدانية والمؤقتة. تتراوح قدرة هذه المحولات من 100 فولت أمبير إلى 1500 فولت أمبير، وتقوم هذه المحولات بتخفيض أو زيادة جهد التيار المتردد الرئيسي بأمان لتتناسب مع المدخلات المقدرة لأنظمة التحكم ومعدات الاختبار وأجهزة الاتصالات والأحمال الصناعية الصغيرة.

تُعد محولات الجهد المتنقل هذه مثالية للمستخدمين الصناعيين والمنشآت التجارية ومقاولي الكهرباء وفرق الخدمة الميدانية التي تنشر المعدات في الخارج أو في المناطق ذات الفولتية غير القياسية للشبكة. تشمل التطبيقات النموذجية لوحات التحكم، وأجهزة التحكم في التدفئة والتهوية وتكييف الهواء، وأجهزة التحكم، وأنظمة الإضاءة، وإعدادات الطاقة المؤقتة، حيث يكون تحويل التيار المتردد المستقر ومنخفض الضوضاء أمرًا بالغ الأهمية.

JOHsunTECH هي شركة مصنِّع ومصنع محترف لمحولات الجهد الكهربائي المتنقلة، وتخدم الموردين والموزعين وتجار الجملة وشركاء تصنيع المعدات الأصلية/التصنيع حسب الطلب في جميع أنحاء العالم. نحن ندعم التكوينات المخصصة، والعلامات التجارية الخاصة، وانخفاض موك وأسعار الجملة التنافسية، مما يتيح للمشترين من الشركات بناء خطوط إنتاج مرنة ومتماشية مع العلامة التجارية للأسواق الصناعية والتجارية.

■ 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.

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 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.
