Thyristor rectifier

SCR circuit structure

SCR characteristics

1.Excellent environmental adaptability and corrosion resistance
In the design and manufacture, the equipment may work in harsh environment, especially pay attention to the design of ventilation duct, the sealing and isolation of control system, the end sealing of transformer and the treatment of high voltage line joints, so as to improve the process quality and anti-corrosion ability of rectifier.The equipment is sturdy and durable.
2.Perfect protection function
It has perfect protection circuit in steady current working time limit voltage, steady voltage working time limit current, lack of phase, short circuit and overheating.
3.Significant energy saving
SCR series rectifiers use innovative high-efficiency converter structure composed of large-capacity and low-loss Schottky rectifier diode and bridge rectifier transformer, thus making the efficiency of large-capacity SCR reach a new level.
4.Small, lightweight and space-saving
Optimized rectifier structure, excellent cooling system design and reasonable process design make the rectifier simple and lively in structure, small in size, light in weight and small in volume.In addition, it can be installed in layers, which can save precious space for users.
5.Effective control function
* Remote control by wire operation
* Stabilized voltage/steady current operation mode can be set as required
* The steady voltage value and steady current value can be set separately
* Current density compensation value can be set for steady current voltage
* Low current alarm can be set
* Settable low voltage alarm
6.Multiple choices of remote control operation box
The rectifier is designed according to the uniform interface standard, and is matched with a variety of operation boxes to meet the different operation needs of customers.
7.Cooling options
