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 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 is basically water-cooled, also the three-proof treatment adopted for the internal components which can achieve effective heat dissipation of the rectifier and protection of the internal components of the rectifier. This series power supplies can cover all the above-mentioned applications, featured for complete control functions, stable performance and high cost performance.
Features
Isolated input and output for safe operation. Advanced soft-switching technology and multi-loop control adopted to ensure output precision & stability. High-power isolated gate bipolar IGBT & Nano scale material high frequency transformer adopted. Output voltage & current separately adjustable. CC voltage-limit / CV current-limit working modes, manual-switchable. High efficiency, full protection functions, like lack phase, over voltage, lack voltage, short-circuit, over current and over heat protection. With RS485 communication interface, in line with MODBUS-RTU communication protocol. Small size & Low weight.
N+1 redundant system description
Advanced current mode control & N+1 power redundant design adopted for whole power system, this control mode gives good current-sharing effects, low deviation and high CC/CV precision. This rectifier adopts N+1 redundancy system which taking redundant into account, total real output power 125% of rated value which give the rectifier system good over-loading ability, for example: Total rated power is 22V8000A, the power cabinet has four units inside in four floors, rated power of every unit is 22V2000A, each power unit has 2000A rated output current. Fault of any-one unit would not impact the whole rectifier; the other power units would compensate power loss and keeps output capacity. You could repair & replace the faulty unit without power absence, you could continue with the remaining power units. It has completely improved the irreparable work defects of traditional rectifiers, such as high energy consumption, instability, long maintenance time and delay in production. Really realized: energy saving, stable, uninterrupted work!

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.
