product description
SG-P (DG-P) series products are imported high-quality cold-rolled silicon steel sheets, with reasonable structure, high reliability, anti-interference, good safety performance, high efficiency, low noise, and are widely used in UPS bypass and neutral ground voltage removal. , Imported equipment with high requirements for pure sine wave power supply voltage and other occasions.
The transformer adopts three-column iron core, Y/Y0 or △/Y0 connection, good insulation between the primary and auxiliary coils, and adopts double shielding isolation (adding shielding further eliminates the high-frequency pulse interference and noise coupled by the transformer, However, although the shielded isolation transformer can effectively prevent interference from various NGs (pulse and high-frequency noise), the transformer must be properly grounded). The secondary circuit is protected from power grid and external high-frequency electromagnetic wave interference and safe manual operation. The body is installed in the protective net cover to ensure good heat dissipation.
