Product Description

 

Product Description

Description:

This transformer supplies auxiliary power for engineering equipment control units. It ensures stable power supply through transformation and isolates interference to protect control units. It is a crucial guarantee for the reliable operation of the control system, maintaining precise control and stable operation of the equipment.

1.Stable Output for Reliable Power Supply

Adopting advanced voltage stabilization techniques and precise winding processes, it has extremely high output voltage stability. Even when the grid voltage fluctuates or the load changes in engineering equipment, it can continuously provide stable and pure power for control units, avoiding malfunctions or failures caused by power issues.

 

2.Isolation Protection with Strong Anti-interference Capability

It has good electrical isolation performance, effectively isolating interference signals such as surges and spike pulses from the grid side. At the same time, it prevents internal faults of control units from affecting the grid and other equipment, enhancing the anti-interference ability of control units and ensuring normal operation in complex electromagnetic environments.

Operation Environment

A)Altitude: Not exceeding 1000m, shall be derating used if above 1000m;
B)Ambient Temperature: -25D-55D;
C)Relative Humidity: <95%;
D)As to the installation site, to make sure no bad effect on transformer
insulation such as chemical déposition, dust, and other explosive or erosive medium.
