Low voltage SG series Isolation Power Transformer

low-voltage isolation transformer with a voltage rating of 0.4/0.23 kV is a specialized electrical device
designed to provide galvanic isolation between two circuits. It is commonly used in industrial, commercial,
and residential applications to ensure safety, reduce electrical noise, and protect sensitive equipment from
voltage fluctuations or surges.
The primary function of this transformer is to step down the voltage from 0.4 kV (400 V) to 0.23 kV (230
V) while maintaining complete electrical isolation between the input (primary) and output (secondary)
windings. This isolation prevents direct electrical contact, reducing the risk of electric shock and improving
overall system safety. Additionally, it helps eliminate ground loops, which can cause interference in sensitive
electronic devices.
Constructed with high-quality materials, the transformer features a robust core made of laminated silicon
steel to minimize energy losses and ensure efficient operation. The windings are carefully insulated to
withstand high temperatures and provide long-term reliability. The design also incorporates thermal protection
mechanisms to prevent overheating under heavy loads.
