Overview
STP series DC rectifier is a rectifying type DC power supply based on high frequency switching technology of IGBT switching components. It is a product specially developed by our company for industrial applications such as electroplating, electrolysis, water treatment and hard oxidation. Compared with the traditional thyristor rectifying power supply, this series of rectifier power supplies can reduce the clients' power consumption by 20%~30%. In order to overcome the harsh environment of the applications and the long-term running conditions, the rectifier power supply is basically water-cooled, also the three-proof treatment adopted for the internal components which can achieve effective heat dissipation of the power supply and protection of the internal components of the rectifier. This series rectifiers can cover all the above-mentioned applications, featured for complete control functions, stable performance and high cost performance.

Main Transformer
High-frequency Nano crystalline transformer. The transformer is a case type structure. This case is not only the protective layer, but also the output of the transformer, and it also can provide cooling water channel. Another advantage is its large conductive area, small heat. Because the transformer adopts the novel structure, the conformity of production produced is high; it is especially suitable for high power supply manufacturing.

Maintenance
Check whether the bolts or moisture loosen regularly Check whether water leakage at pipe connection regularly Check whether any leaking of water pipe connection regularly. Regularly open the box side plate, cleaning dust inside. Regularly with clip-on ammeter check three-phase input current that it is abnormal and serious drift phenomenon, if abnormal, contact the supplier in time. Specially assigned person for equipment maintenance.
Installation environment
Ambient temperature: Please have the power source working in safe temperature range (0ºC ~ 45ºC) or it would affect life of power source. Please install the power source at least 50cm distant from surroundings to have better ventilation. Please install the power source away from vibration (less than 0.6G), especially equipment like puncher. Keep the power source away from direct sunshine, humidity or place with water globule. Keep the power source from corrosive, flammable & explosive gas. Keep the power source away from oil stain, dust & metallic dust.
