Project Description
Part number 8440-1935
Belonging to EasyGen-3500 series
Function type: Generator Controller
The series is positioned as a mid to high end model between EasyGen-3000 and EasyGen-3200XT
Reference models of the same level include 8440-1934 (5/P1), 8440-1936, 8440-2050E, and 8440-2052H
8440-1934 corresponds to Control-EASYGEN-3500-5/P18440-1935, which should be a variant model with similar configurations in the same series (such as different firmware versions or I/O configurations).

Main functions
Generator voltage/frequency regulation: automatically maintains rated voltage (± 0.5%) and frequency (± 0.1%)
Parallel control: supports parallel operation of multiple generators, load sharing
Protection functions: over/under voltage, over/under frequency, over-current, reverse power, short circuit protection
Communication interface: Supports POWERLINK/Modbus/CAN bus and interfaces with the upper computer monitoring system
Engine interface: Can be connected to Woodward speed controllers (such as 8280/9907 series) to achieve coordinated control of the unit

Key technical parameters (refer to 8440-1934 of the same level)
Weight approximately 2.32 kg
Working temperature: 0 ℃~65 ℃
Storage temperature -40 ℃~85 ℃
Certification CE
Installation method: DIN rail/panel installation
Front panel LED status indicator+button/knob operation
Input voltage 24 VDC (control power supply)
Output relay output (trip/close), analog output (4-20mA)
