DSE 335 MKII Automatic Transfer Switch Control Module For Sale

The Deep Sea Electronics DSE335 MKII is a fully automatic transfer switch controller engineered to manage the seamless transfer of electrical load between two AC power sources—typically mains (utility) and a backup generator. Designed for reliability and flexibility, the DSE335 MKII continuously monitors voltage and frequency parameters from both sources and ensures a fast, intelligent switchover in the event of supply failure or instability. Ideal for a wide range of applications, including commercial buildings, industrial facilities, and standby generator systems, this module helps prevent power loss, equipment downtime, and unnecessary engine starts.

Key Features and Capabilities

• Automatic Source Monitoring: Monitors both Source 1 (S1) and Source 2 (S2) for voltage, frequency, and phase failure. Automatically initiates switchover upon detecting failure or instability.

• Configurable Inputs and Outputs:

  • 12 configurable inputs

  • 6 configurable volt-free outputs

  • 6 configurable DC outputs

• Flexible Application Support: Supports single or dual switching schemes, rotary ATS configuration, and multiple power topologies for versatile deployment.

• Advanced Closed Transition Control: Configurable closed transition settings (<100 ms) help prevent momentary outages during switching.

• User-Friendly Interface: Features a back-lit 4-line LCD display, LED alarm indicators, and a 5-key navigation menu with front panel editing protected by PIN.

• Robust Communication Options:

  • RS485 communication port

  • USB connectivity for PC-based configuration

  • Ethernet monitoring (via DSE855 module)

  • Modbus support with adjustable inter-frame delay

• Real-Time Monitoring & Logging: Integrated real-time clock for accurate event recording and a range of power metering options including kWh, kVAr, kVAh, and more.

• Load Control & Optimization: Supports load shedding outputs, start/load inhibit, check sync features, and passive closed transition.

• Programmable Logic Controller (PLC): Built-in 200-node PLC editor for complex application-specific logic and SCADA integration.

• Multilingual & Configurable Display: User-selectable display languages and customizable Gencomm pages for international and specialized applications.

• Rugged and Secure: IP65-rated front panel protection (with gasket), secure PIN access, and reliable alarm management.
