Variable Transformer Rectifier
Product introduction
Variable transformer rectifier is a traditional rectifier, it is composed of a control circuit and an analog circuit, display part is single display by digital gauge or analog gauge, the operation interface consists of potentiometer and select switch.
Impressed current cathodic protection(ICCP) system is a Metal corrosion protection technology widely used in the corrosion industry.The steel body results are protected against corrosion by using the ICCP technology.Variable transformer rectifier is one of the most widely used rectifiers in impressed current cathodic protection system.
Variable transformer rectifier is a power supply similar to Tapped transformer rectifier. It does not need to output current through the stepping switch. By using the Variable transformer, it overcomes the short board of the Tapped transformer rectifier's output leaping regulation and realizes the non-pole regulation of 0~100% of the output voltage.
- Product Features:
- Adjustable voltage range: The output DC voltage can be continuously or stepwise adjusted within a certain range to meet the voltage requirements of different loads.
- Simple operation: Equipped with corresponding control mechanisms and adjustment devices, the operation is relatively simple and convenient. It can be adjusted on-site through manual knobs, buttons, etc., and can also be equipped with a remote control interface to achieve remote monitoring and adjustment, facilitating centralized management and automated control.
- Strong durability: Usually, mature transformer and rectifier technologies are adopted, featuring high reliability and stability. With reasonable design and strict quality control, it can maintain good performance during long-term operation, reduce the probability of faults and lower maintenance costs.
