DC power distribution cabinet
Main Features
Supply 30-500kw grade inverter distribution.
Use domestic and foreign well-known brands photovoltaic
DC circuit breaker,working voltage up to 1000V,with reliable performance.
Cabinet input end can be configured with prevent
reverse diode to prevent reverse connection & short circuit and protect the
combiner box and inverter.
Each input or output can be configured with DC current
sensor to monitor and measure the input & output current.Confluence output
end configured with voltage transducer to supervise PV output voltage and
working condition of the circuit breaker’s input and output.
Supervise insulation condition of input and output
circuit,ensure the safety and stable performance.
Provide different grades of lighting protection
systems at customer’s demand,protect circuit breaker and inverter effectively
from overvoltage.
