ESD5550E Speed Control Unit for Diesel Generators

The ESD5550E Speed Control Unit is a highly reliable all-electronic device designed to manage engine speed with rapid and precise responses to transient load changes. This closed-loop control system connects seamlessly to a proportional electric actuator and operates using a magnetic speed sensor signal, making it suitable for various engines in both isochronous and droop modes. Built to withstand harsh engine environments, the unit ensures durability and consistent performance.

Key Features:
– Fast and Precise Control: Delivers optimal engine speed response to load variations.
– User-Friendly Design: Simplified installation and adjustment, featuring non-interacting performance controls for easy optimization.
– Starting Fuel and Speed Ramping Adjustments: Reduces engine exhaust smoke during startup by allowing controlled fuel delivery and gradual acceleration to operating speed.
– Adjustable Droop and Idle Operation: Tailors performance to specific engine requirements.
– Multi-Engine Compatibility: Includes inputs for accessories to support multi-engine setups and special applications.
– Robust Protection Mechanisms: Safeguards against reverse battery voltage, transient voltages, accidental actuator short circuits, and features a fail-safe design in the event of speed sensor or battery loss.

The ESD5550E is compatible with all proportional actuators, except for the ACB2000 electric actuator. When paired with the ADC100 Series electric actuator, the droop adjustment range may be reduced due to its lower current demand.

This makes the ESD5550E an excellent choice for reliable engine speed control in diesel generator applications.
