Frequency volatility ≤0.5% voltage harmonic distortion <4% no-load voltage setting range of 95% to 105% of ≥90% efficiency generator set noise ≤102dBA (at 1m from the unit) with built-in vibration damping device and use anti-aging complex material, DSE7420, the unit can be placed directly on the room floor. The maximum amplitude <0.05cm relative humidity ≤95% Working temperature -10 ℃ ~ + 50 ℃ operating electrician took over diesel generator sets, first to verify what the three points? A: The real useful power 1) to verify the unit. Then determine the economic power, and backup power. Approved unit real useful power of method: diesel 12 hours multiplied by 0.9 to arrive at a rated power of data (kw), if the generator rated power less than or equal to the data, special DSE7420, places to nominal power generator unit for real useful power, if the generator rated power is greater than the data, you must use the data as a real useful power unit. 2) verify the unit with which several self-protection. Spot DSE7420 | Deep Sea Original (Online) | DSE7420 provided by the Dongguan City Nancheng Zhongxin Electrical and Mechanical operation.
