Product Details

Product Overview
The DG series single-phase isolation transformer is a safe and protective isolation transformer. Our company adopts advanced manufacturing technology and has imported winding machines and a complete set of vacuum pressure coating equipment. The windings are wound in a whole line by the method of detachment, and the transformers are vacuum coated to achieve insulation levels of F or H. Our products comply with international and national standards such as VI) E0550, IEC439, JB5555, GB5226, etc.
The DG series single-phase dry-type isolation transformer is widely used in various power supply scenarios such as computer rooms, hospitals, factories, communication base stations, etc. with AC 50/60HZ and input and output voltages not exceeding 1000V. The allocation of various input and output voltages, connection groups, and tap line group capacities of the product can be carefully designed and manufactured according to user requirements.
main function
1. Isolate static electricity
2. Isolate load leakage interference current
3. Input/output 1:1 electrical isolation
4. Overcome center drift and improve power imbalance
5 . Surge protection and filtering function
6. Output safe voltage to prevent leakage switch tripping and power failure
