WOODWARD 8440-1445 Industrial grade grid connected controller
Specific parameters
Input power supply: 24VDC ± 15% (minimum operating voltage 18VDC)
Signal processing: 12 bit ADC sampling, refresh rate of 100ms (configurable up to 50ms)
Environmental tolerance: Operating temperature: -25 ℃~70 ℃ (natural cooling)
Output capability: 6-way relay output (contact capacity 3A/250VAC)
Product Performance
Synchronization accuracy: Supports closed contract period detection, with a tolerance range of ± 5% for voltage difference, ± 0.2Hz for frequency difference, and ± 10 ° for phase difference, ensuring smooth grid connection.
Protection logic: Built in 12 protection functions including overvoltage (threshold can be set to 110% Un), undervoltage (80% Un), reverse power (adjustable threshold, default -10% Pn), etc.
Communication interface: Modbus RTU (RS485) is standard, and CANopen (WCM-1000-CAN module needs to be expanded) is optional.
Usability: Quickly configure parameters through Woodward Toolkit 2.0 software and support one click firmware upgrade.
Reliability: Certified by UL 508A and IEC 60204-1, with an MTBF (Mean Time Between Failures) of 100000 hours.
