■ How to Choose This Transformer
Ten kilovolt-amperes is distribution-scale, so size for the expected simultaneous load rather than the sum of everything installed. Diversity in a real workshop or laundry is rarely 100 %, but the heaviest motor still sets the ceiling: on this frame allow about 5,200W of resistive load, 3,200W of fan and pump duty, or 1,600W of compressor load. We normally recommend planning so that the usual operating load sits at around 70 % of the rating.
Three items to settle before ordering:
- whether the secondary will feed a sub-board or a single machine, which determines conductor and breaker sizing;
- the conversion direction together with the socket standard for your market;
- the mounting position and the clearance available for convection cooling.
■ System Design Around a 10KVA Frame
At 110V and 5,200W the secondary current approaches 47A, which calls for a cable cross-section far larger than an equivalent 220V circuit — under-sizing the secondary cable is the most common installation error we see on 10KVA projects. The unit ships one to a carton at 42.5 × 33 × 28cm and is normally wall-bracketed or set on a plinth; it is heavy enough to need two people. Each unit is dielectric-tested and then run at rated load, with output voltage, no-load current and winding resistance recorded against the serial number for twelve months.
Where the connected load genuinely exceeds the figures above, two 10KVA frames on separate circuits are often more economical than moving to a non-standard rating. Discuss the duty cycle with us before assuming a bespoke build is required.
The unit is heavy enough to need two people when positioning it on a bracket or plinth. Wooden-crate packing is available for export shipments where the standard carton is not considered sufficient.

- 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.

■ FAQ
What is the Johsun DT 10000VA designed for?
The Johsun DT 10000VA is the top of the DT range and the only model supplied one unit to a carton. It is built for distribution-scale duty: a single unit feeding a sub-board, a CNC cell, a commercial laundry or a small production floor that runs entirely on equipment of the opposite voltage class. Where two smaller frames would be needed on separate circuits, one Johsun DT 10000VA usually works out cheaper to install.
Can a 10kVA step up transformer feed a whole sub-board?
Yes, and that is its normal role. A 10kVA step up transformer supplies approximately 5,200W of resistive load, 3,200W of fan and pump duty or 1,600W of compressor load, which is enough for a small distribution board once diversity is taken into account. Work from the expected simultaneous load rather than the sum of everything installed, and plan so the usual operating load sits at around 70% of the rating.
Is a 10000 watts step down power transformer 220V to 110V available with a custom socket?
Yes. A 10000 watts step down power transformer 220V to 110V can be supplied with a market-specific socket, a fixed ratio instead of a selector, a resettable breaker, or a branded front panel. Because the frame is normally hardwired rather than plugged in, most buyers specify the terminal arrangement instead of a socket, and we will confirm the terminal layout against your panel drawing.
What cable size does the secondary need?
At 110V and 5,200W the secondary current approaches 47A, which requires a far larger conductor cross-section than an equivalent 220V circuit. Under-sizing the secondary cable is the most common installation error we see on 10KVA projects, so size the cable for the current over the full run length and protect it with its own breaker rather than relying on the primary device.
How is a 10KVA unit packed and delivered?
One unit per carton at 42.5 × 33 × 28cm. The frame is heavy enough to need two people when it is positioned on a wall bracket or floor plinth, and wooden-crate packing is available for export shipments where the carton alone is not considered sufficient. Standard lead time is 10–20 working days, extending to 15–25 working days for custom voltages or branded panels.
