product introduction:
ZQA rectifier converts AC power supply into DC power supply, which is suitable for rated output voltage DC1800V and below and rated output current to 2400A. It is suitable for trolley buses, trams, rail transit, mine traction converter systems, and converter systems in applications such as electrolysis and steel rolling.

product introduction:

ZQAtype rectifier converts AC power supply into DC power supply, suitable for rated output voltage DC1800V and below, rated output current to 2400A, suitable for trolley buses, trams, rail transit, mine traction converter system, as well as electrolysis and steel rolling and other applications of the converter system.

product features:

  1. High-efficiency energy conversion, significant energy saving, using 12-pulse/24-pulse rectifier, the efficiency of the whole machine is ≥ 97% ~ 99%, and the loss is extremely low.
  2. Stable DC output, strong resistance to network voltage fluctuation, wide input voltage adaptation range, high stability of output DC voltage (DC 750V/1500V).
  3. Intelligent and remote monitoring, built-in PLC/special controller, to achieve automatic flow, fault recording, condition monitoring. Support remote communication (Modbus, Profibus, Ethernet), access to SCADA system, to achieve unattended.
  4. Compact structure, high power density, standardized cabinet design.
