The DSE7320 controller is the MKII generation Auto Mains Failure (AMF) genset control module from Deep Sea Electronics, built for automatic transfer switching on single-phase and three-phase diesel or gas generator sets. POPULACE supplies the DSE7320 controller as a direct-fit replacement and professional service module. The DSE7320 controller monitors mains and generator voltage and frequency continuously, starting the genset and transferring load when mains parameters fall outside configured thresholds. With an 8V to 35V DC supply, the DSE7320 controller suits both 12V and 24V genset systems. For service technicians, the DSE7320 controller offers a user-friendly interface with configurable protection and alarm parameters. Available as part number 7320-03, the DSE7320 controller is stocked by POPULACE for fast international dispatch to distributors worldwide.

The DSE7320 controller generates fuel and start outputs at 15A DC each, providing direct drive capability for standard engine start circuits. Two volt-free relay outputs (C and D) on the DSE7320 controller are rated at 8A 250V for load transfer contactor control. Four auxiliary outputs (E through H) on the DSE7320 controller deliver 2A DC each, configurable for cooldown timers, alarm annunciators, or auxiliary relays.

The DSE7320 controller monitors mains voltage from 15V to 415V AC phase-to-neutral (26V to 719V AC phase-to-phase), and the generator input of the DSE7320 controller covers the same range, supporting both low-voltage and high-voltage genset configurations. The frequency acceptance of the DSE7320 controller spans 3.5Hz to 75Hz, covering 50Hz and 60Hz systems globally. For magnetic pickup speed sensing, the DSE7320 controller accepts ±0.5V to 70V at frequencies up to 10,000Hz, handling a wide range of flywheel tooth count configurations. The charge fail/excitation input on the DSE7320 controller accepts 0V to 35V for standard alternator sensing across both 12V and 24V systems. The DSE7320 controller measures 245mm x 184mm x 51mm overall, with a panel cutout requirement of 220mm x 160mm and a maximum panel thickness of 8.0mm.

• Auto Mains Failure Detection: The DSE7320 controller continuously monitors mains voltage and frequency, initiating automatic genset start sequences when mains parameters fall outside configured limits.
• Wide DC Supply Range: The DSE7320 controller operates from 8V to 35V DC, covering standard 12V and 24V genset battery systems without external voltage regulators.
• Multiple Output Channels: The DSE7320 controller provides fuel, start, two volt-free relay, and four auxiliary DC outputs, giving panel integrators flexible switching capability for diverse configurations.
• Wide AC Voltage Monitoring: The DSE7320 controller monitors both mains and generator voltages up to 719V AC phase-to-phase, supporting low-voltage and higher-voltage genset applications.
• Magnetic Pickup Speed Input: The DSE7320 controller accepts magnetic pickup signals at up to 10,000Hz, supporting a wide range of engine flywheel tooth count configurations without additional converters.

The DSE7320 controller combines AMF logic, engine protection, metering, and load transfer control in a single panel-mounted unit, replacing multi-device arrangements that require additional wiring and maintenance. The MKII hardware of the DSE7320 controller adds configurable features and parameter options compared to the original 7320, while keeping the user-friendly interface format that DSE-trained service technicians recognize.

The wide AC voltage acceptance of the DSE7320 controller covers both standard 230/400V distribution and higher-voltage generator configurations, reducing the need for regionally different hardware variants. The magnetic pickup input on the DSE7320 controller handles a broad flywheel tooth count range without additional frequency converters. For genset fleet managers, standardizing on the DSE7320 controller simplifies spare parts inventory and reduces service training requirements. POPULACE manufactures the DSE7320 controller to Deep Sea Electronics specifications, ensuring accurate fit and function in every replacement.

Q: What is the function of the DSE7320 controller?
A: The DSE7320 controller is an Auto Mains Failure (AMF) module that monitors mains power and starts the generator automatically when mains voltage or frequency goes outside configured limits. The DSE7320 controller then transfers load to the generator and returns it to mains once power is restored and stable.

Q: What DC supply voltage does the DSE7320 controller require?
A: The DSE7320 controller operates on 8V to 35V DC, making it compatible with standard 12V genset systems (340mA operating, 160mA standby) and 24V genset systems (160mA operating, 80mA standby).

Q: How is the DSE7320 controller installed in a panel?
A: The DSE7320 controller requires a 220mm x 160mm panel cutout with a maximum panel thickness of 8.0mm. A qualified engineer installs the DSE7320 controller following Deep Sea Electronics commissioning documentation, connecting mains and generator sensing inputs, engine control outputs, and load transfer contacts before configuring alarm thresholds and transfer parameters on the DSE7320 controller.
