(1) The automatic switch, which requires both electrical chain, but also with a mechanical linkage, DSE4520 deep sea, two-way all the way into the line outlet structure ensure that the entire circuit can be only one power supply is turned on, to avoid the two-way power turned on simultaneously counter-power transmission. Automatic switch having "IO-II" three positions to facilitate circuit maintenance, and set three remote monitoring interface and implement software, easy to monitor switch automatic switching and manual switching. (2) the unit automatically shut down and manual shutdown should have two normal stop and emergency shutdown. Prelubrication (3) of the unit, starting and stopping, FM and voltage, power transmission, and power failures should be able to manual control. There is a generator with load after its voltage and frequency are stable, DSE4520 production, but the current instability, DSE4520, its problems lie? A: The problem is that customers load unstable, the generator quality is absolutely no problem. A generator frequency instability, the main problems lie? A: The main problem is that the generator speed instability. Manufacturers DSE4520, DSE4520, faithful electromechanical provided by the Dongguan City Nancheng Zhongxin Electrical and Mechanical operation. Dongguan Nancheng Zhongxin Electrical and operating (zhongxin888.net.cn) strong, credible, Dongguan, Guangdong in the industrial products industry has accumulated a large number of loyal customers.
