product advantages
Multi-level safety interlock protection
The device is equipped with a triple intelligent interlocking system, using real-time display and mechanical locking device to eliminate the risk of opening the door by mistake. The high and low voltage interlock logic avoids misoperation from the source, and is equipped with human body induction lighting and voice prompt functions to assist operation and maintenance personnel in standardizing operations, greatly improving the safety of on-site operations.
large enterprise scale
The built-in passive filter module can accurately filter out 3rd, 5th and 7th harmonics, and the harmonic rejection rate exceeds 85%, which conforms to IEC power quality standards. The integrated structure does not require additional space, and the filtering scheme can be customized according to the inverter, charging pile and new energy load, effectively reducing equipment aging and line loss caused by harmonics.
Adaptive operation in harsh environments
Equipped with an intelligent temperature and humidity control system, with automatic dehumidification and heat dissipation functions; the protection level of the whole machine is IP44, and the shell adopts anti-corrosion coating, which can operate stably in a wide temperature, high humidity and dusty environment from -25℃ to 45℃. It is suitable for harsh working conditions such as industrial plants and underground power distribution rooms. No additional protective equipment is required.
Energy-saving and low-consumption + remote intelligent operation and maintenance
Using low-loss copper strips and high-precision electronic components, the no-load loss is 30% lower than that of traditional equipment, which meets the EU energy-saving standards. The integrated monitoring platform can collect data in real time, perform remote control, and issue abnormal sound and light alarms to achieve centralized operation and maintenance, greatly improving management efficiency. Support the customization of voltage levels, cabinet structures and functional modules to meet the differentiated needs of different projects.
