| Standard Control Panel | ||
 | Dingbo Standard Control Panel uses micro processing technique integrating digital, intelligent and network techniques which can carry out functions including auto start/stop, data measure, alarming. The controller uses LCD display, optional Chinese and English display interface with operation easy and reliable. It can be widely used in all types of generator automatic control system for compact structure, advanced circuits, simple connections and high reliability | |
| Auto Module Control Panel | |
 | Auto Module Control Panel is the configuration for nobody on duty controlling generators. This kind of panel adopts auto module control system, with large LCD display to show the menu. Features: 6110 can receive remote output signal from ATS and realize auto start and stop of generators. 6310 can realize all functions of 6110, add RS232 interface which can communicate with PC to realize remote operation. 6410 Auto Mains Failure controller, can realize all functions of 6310, furthermore can detect ATS and control directly. |
| Auto Parallel Control Panel | |
 | This new automatic parallel system adopts intelligent modules, inserted and folded installed, no need the peripheral relay and logic circuit. The main switch adopts electronic breaker or frame breaker, combined together with the generator, which is very reliable. One generator, one panel. The panel can be used both for singly and parallel. It is only need to parallel generator with such panel when the capability needs to be enlarged in the future. |
