Ankerui APG intelligent photovoltaic lightning protection DC cabinet

The intelligent photovoltaic lightning protection DC cabinet is a function cabinet for summarizing, monitoring and protecting the DC power after the convergence of the photovoltaic combiner box. The DC lightning protection cabinet can aggregate the multiple DC inputs into one current output, and each circuit has a protection device (circuit breaker). , fuses, etc.), anti-reverse diodes, etc., and can monitor each voltage and current, and can achieve remote communication. 1. Product Features High-performance components and intelligent design. It has the advantages of high cost performance, beautiful appearance, convenient installation and use. It can monitor multiple current, voltage, power and switch status, and communicate with the monitoring system through RS485 communication interface to realize intelligent management of DC power distribution cabinet. Modular design, components adopt international or domestic famous brands, with excellent performance, safe and reliable. The internal wiring is reasonable and beautiful; the lightning protection grounding meets the technical requirements of lightning protection specifications. High breaking capacity, good thermal stability, flexible and convenient combination of electrical solutions, and practicality, can be customized according to customer needs.
