Description
3-Phase ABS Duplex Intelligent Pump Controller
The three-phase intelligent pump controller designed for
dual-pump industrial systems. It supports multiple control logics including duty/standby
operation, automatic alternation, and simultaneous pump operation.
Engineered with an IP65 flame-retardant ABS enclosure and a comprehensive
17-protection safety system, the controller ensures reliable pump management in demanding
applications such as water supply systems, drainage stations, cooling systems, and industrial pump rooms.
