■ How to Choose This Regulator
The output of a manual regulator is set by hand and can be varied smoothly and continuously from zero up to the maximum value, so the first question is not capacity but whether you need an adjustable supply at all. A fixed-ratio transformer is the cheaper answer when one voltage is required; a regulator is the right choice for calibration, development work, motor speed tests and any application where the voltage has to be dialled in. Once that is settled, size the rating from the maximum current the load will draw at the highest output voltage you intend to use.
Three points to confirm before ordering:
- the maximum output voltage and current required, since capacity is set by the product of the two;
- the input supply voltage at the installation;
- whether an output meter is needed — it is fitted as standard on the larger models in the family.
■ Using an Adjustable Output Safely
Because the knob can be turned to any position, the practical discipline is to preset the output to zero, connect the load, and bring the voltage up while watching a meter. The provision of a meter and indication makes that straightforward on the larger frames. These regulators are used in industry, agriculture and research, and are particularly suited as ancillary equipment for machine tools, curve tracers, projection television sets and analytical instruments in the petroleum sector. The output is taken from a brush contact on the winding, so periodic inspection of the brush and the track is worth including in a maintenance schedule.
■ 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.
