产品摘要

The isolation transformer usually means 1:1 transformer. As the secondary is not connected to the ground, there is no potential difference between any piece of line of secondary and the ground, thus reducing various clutters and interferences. Featuring wide applicable loads, able to withstand instantaneous overload, long-time continuous operation, water and moisture resistance, safety, reliability, energy-saving, and convenient maintenance, the isolation transformer is widely applied to various three-phase power supply situations with AC 50~60HZ and input and output voltage not greater than 500V.

产品介绍

1. Brief Description
The isolation transformer usually means 1:1 transformer. As the secondary is not connected to the ground, there is no potential difference between any piece of line of secondary and the ground, thus reducing various clutters and interferences. Featuring wide applicable loads, able to withstand instantaneous overload, long-time continuous operation, water and moisture resistance, safety, reliability, energy-saving, and convenient maintenance, the isolation transformer is widely applied to various three-phase power supply situations with AC 50~60HZ and input and output voltage not greater than 500V. The input and output voltage (single-phase, three-phase or multi-way input and output, etc), connection mode, position of adjusting tap, distribution of winding capacity, configuration of secondary winding, and outer tank (chosen according to service environment) of the product may be elaborately designed and manufactured according to user requirements. 

2. Application Scope
The main effect of isolation transformer is to isolate the electrical equipment from power grid, and it is used where safety or anti-interference is required, without direct electrical contact between electrical equipment and power supply.
