DSE8660 MKII

Features:

• Mains Supply Monitoring and Automated Generator Set Control
• Built-in Synchronising and Load Sharing with Demand-Based Management
• Multiple Communication Interfaces, Configurable Inputs and Protection Functions

The DSE8660 MKII operates as an advanced Auto Mains (Utility) Failure controller within a generator control system, providing intelligent monitoring and automated control of one or more generator sets equipped with DSE8610 MKII controllers. The DSE8660 MKII is specifically designed to handle mains supply monitoring and automatic generator set management, solving the problem of maintaining continuous power availability through automated start/stop sequences based on real-time utility supply status. It continuously monitors the mains supply and automatically initiates generator start procedures when mains failure is detected, distributing synchronising and load sharing commands through the network to ensure seamless power transfer. Seamless integration is standard with the DSE8660 MKII, and using its built-in synchronising capabilities allows multiple generators to operate in parallel with the mains or in island mode as required. The DSE8660 MKII incorporates a powerful ARM microprocessor enabling complex features including true RMS voltage, current and power monitoring, a text-based LCD display, fully configurable inputs for use as alarms or a range of different functions, and multiple communication options including USB, RS232, RS485 and Ethernet.

The DSE8660 MKII provides essential control functions critical to the entire generator system, serving as a vital component of the power management path that directly affects proper, normal operation of the overall parallel generation system. This DSE8660 MKII controller is specifically designed to handle complex power system monitoring and control, solving the problem of integrating diverse operational requirements into a single, flexible control platform. One DSE8660 MKII module is typically required per system to manage mains monitoring and generator control functions. The DSE8660 MKII is housed in a robust plastic case suitable for panel mounting, occupying a compact installation footprint with connections via locking plug and sockets for secure wiring.

For parallel operation with the mains supply, the DSE8660 MKII system utilises advanced protection features including R.O.C.O.F. (Rate of Change of Frequency) and vector shift protection to detect mains failure conditions even when operating in parallel with the utility. The DSE8660 MKII is specifically designed to handle critical mains failure detection in parallel applications, solving the problem of traditional protection methods that may fail to detect utility supply issues during parallel operation. In addition to standard automatic transfer operation, the DSE8660 MKII also performs load demand start/stop functions to optimise generator running hours. The DSE8660 MKII continuously monitors system frequency and voltage vectors using its advanced detection algorithms. If the module detects that the mains supply is no longer stable (outside configured frequency or vector shift tolerance levels), it will automatically initiate generator start sequences, transfer the load to the generator sets, and log the event in the internal data logging system. The built-in integral PLC further allows customisation of operational logic where specific application requirements demand unique control sequences.
