Overview
The DSE703 is a microprocessor-based generator set controller that provides automatic engine start/stop sequencing, AC power monitoring, and alarm protection for single diesel or gas generator units. It integrates digital measurement, programmable logic, and communication interfaces into a single panel-mounted module.
Key Features
- Microprocessor-Based Control — 32-bit ARM processor with real-time operating system for fast response to engine faults and mains failures
- True RMS AC Measurement — Generator voltage (L-L/L-N), current per phase, frequency, power factor, kW, kVA, and kWh metering with CT ratio configuration
- Engine Protection Suite — Configurable alarm and shutdown thresholds for low oil pressure, high coolant temperature, overspeed, underspeed, battery over/under voltage, and charge failure
- Configurable Digital I/O — All inputs and outputs user-programmable for custom functions including remote start, pre-heat, ventilation control, and external alarm inputs
- Multi-Brand Engine Compatibility — Supports standard resistive senders (VDO/European curve), magnetic pickup, and CANbus J1939 for electronic ECU engines
- Event & Maintenance Logging — Onboard event recorder with real-time clock stamping; configurable maintenance scheduler with hour/date-based service reminders
