DSE 4520 Deep Sea Genset Controller Auto Mains Failure Compact 140 x 113 x 43 mm

DSE 4520 Deep Sea Genset Controller is a compact control module made for automatic mains failure applications. It is designed to monitor and control a generator when the main power supply fails.

The controller can monitor both generator and mains voltage, frequency, power, current, battery voltage, and engine information. Its clear back-lit LCD display helps operators view important generator conditions.

The original DSE4520 has a compact size of 140 mm x 113 mm x 43 mm and weighs about 0.28 kg.

Key Features

• Auto mains failure control
• Three-phase generator sensing
• Three-phase mains sensing
• Generator and load power monitoring
• Voltage and frequency monitoring
• Generator overload protection
• Battery voltage monitoring
• Configurable inputs and outputs
• Engine speed protection
• Engine hours counter
• Engine pre-heat control
• Engine run-time scheduler
• Engine idle control
• Configurable remote start input
• 50-event configurable event log
• Back-lit icon LCD display
• DSE Configuration Suite PC software support
• CAN and alternator speed sensing
• Optional heated display
• Compact panel-mounted design

The controller supports generator and load measurements such as kW, kVA, kVAr and power factor, helping operators understand generator performance.

Applications

The DSE 4520 is suitable for single-generator control systems where automatic mains failure operation is required.

Typical applications include:

• Diesel generator sets
• Standby power systems
• Commercial backup generators
• Industrial generator systems
• Building backup power
• Generator control panels
• Automatic mains failure panels
• Emergency power systems

Technical Benefits

The controller supports a wide generator and mains voltage range. Generator and mains sensing can cover 15 V to 415 V AC phase-to-neutral and 26 V to 719 V AC phase-to-phase, with a frequency range of 3.5 Hz to 75 Hz.

Its configurable inputs and outputs allow the module to be adapted to different generator control panel requirements. Battery voltage monitoring also helps track the condition of the generator starting supply.

The DSE Configuration Suite PC software provides a practical way to configure and monitor the controller.

Industry Usage

This generator control module can be used in industrial, commercial, infrastructure, and backup power installations. It is useful where a generator needs automatic control and continuous monitoring of important operating parameters.

The compact enclosure makes it suitable for control panels where panel space is limited.

Performance Advantages

The DSE 4520 combines generator monitoring, mains monitoring, protection, and control functions in one compact module. Its back-lit display provides clear information to the operator, while configurable functions allow the controller to be matched with different generator setups.

The module also provides protection functions for conditions such as generator overload and engine-related faults. Its event log can store up to 50 events, making it easier to review previous alarms and operating conditions.
