Product Description

Single-phase isolation transformer product overview

DG-P series single-phase isolation transformer products are our company's use of high-quality cold-rolled silicon steel sheets, reasonable structure, high reliability, anti-interference, good safety performance, high efficiency, low noise, used for UPS bypass, removal of zero-ground voltage, imported equipment High-requirement pure sine wave power supply voltage and other occasions.

 The transformer adopts a three-post iron core with I/I or △/Y0 connection. The primary and secondary coils are well insulated, and double shielding is used for isolation. However, although the shielded isolation transformer can effectively prevent the interference (pulse and high-frequency noise) from various NGs, the transformer must be properly grounded).The secondary side circuit is protected from the power grid and external high-frequency electromagnetic wave interference and manual operation is safe. The body is installed in the protective net cover to ensure safe and good heat dissipation.
