DDG series low voltage high current transformerDetailed product description：

Overview:
The DDG series low-voltage high current transformer is suitable for continuous load testing of electrical equipment such as switches, current transformers, diamonds, short-circuit heating, etc. with a rated frequency of 50 Hz for current rise and heating. Generally, voltage regulation is required on the front side of the power supply to achieve stepless voltage regulation on the low voltage side.

Model meaning:



Ordering Notice:
1. Product model
2. Rated capacity
3. If special low-voltage transformers are ordered for high and low voltage, they can be proposed as special products.
