ESD5570E Speed Control Unit for Diesel Generators

The ESD5570E Speed Control Unit is a reliable all-electronic device designed for precise engine speed control, responding quickly to transient load changes. It operates in a closed-loop system when connected to a proportional electric actuator and magnetic speed sensor, suitable for various engines in both isochronous and droop modes.

Key Features:
– Fast Response: Optimizes engine speed control during load variations.
– User-Friendly Design: Simple installation and adjustment with non-interacting performance controls.
– Starting Fuel and Speed Ramping Adjustments: Reduces exhaust smoke during startup by controlling fuel delivery and acceleration.
– Adjustable Droop and Idle Operation: Customizable performance for specific engine needs.
– Multi-Engine Compatibility: Inputs for accessories to support multiple engines or special applications.
– Robust Protection: Safeguards against reverse battery voltage, transient voltages, accidental actuator short circuits, and features a fail-safe design for speed sensor or battery loss.

The ESD5570E is compatible with all proportional actuators, except the ACB2000. When paired with the ADC100 Series actuator, the droop adjustment range may be reduced due to lower current demands.
