8440-1894 数字控制器 用于单发电机紧急备用应用的开路转换

8440-1894是一种数字控制器，用于单发电机紧急备用应用的开路转换(先开后合)ATS(自动转换开关)控制。当DTSC-50检测到公用设施故障时，它命令发电机启动，并将负载转移到应急电源。当市电恢复时，DTSC-50执行开放转换重新传输，允许发动机在停止前冷却下来。它可以用于1Ph2W、1Ph3W、3Ph3W和3Ph4W系统。DTSC-50显示每个阶段的电压和频率值，以及发动机小时数、维护小时数和转移次数。活动警报通过七段LED显示屏发出。独立的led显示断路器状态和电源可用性。密封软键使用户能够启动发电机并手动操作转换开关。 8440-1894可以用于自动和手动操作。这意味着可以通过远程启动输入来启动发电机。
8440-1894还具有以下特点:
开放过渡转移
公用事业到发电机的应用
远程启动输入

8440-1894

The 8440-1894 is a digital controller for open-switch ATS(Automatic change-over switch) control in emergency backup applications for single-engine motors. When the DTSC-50 detects a utility failure, it commands the generator to start and transfers the load to the emergency power supply. When mains power is restored, the DTSC-50 performs an open transition retransmission, allowing the engine to cool down before stopping. It can be used in 1Ph2W, 1Ph3W, 3Ph3W and 3Ph4W systems. The DTSC-50 displays voltage and frequency values for each stage, as well as engine hours, maintenance hours, and number of transfers. Activity alerts are issued via a seven-segment LED display. Separate led displays circuit breaker status and power availability. The sealed soft key enables the user to start the generator and manually operate the transfer switch. The 8440-1894 can be used for automatic and manual operation. This means that the generator can be started with a remote start input.
8440-1894 also has the following features:
Open transition
Utility to generator applications
Remote startup input
