Environmental Parameters

Operating Temperature: -40℃ to +70℃ (non-condensing environment, compliant with IEC 60068-2-1/2 standard)Storage Temperature: -40℃ to +85℃Relative Humidity: 5% to 95% (non-condensing, compliant with IEC 60068-2-3 standard)EMC Compliance: Meets EN 55022 Class A (emission limits) and EN 55024 (immunity) standards, common-mode interference immunity ≥120dBVibration Resistance: 10-500Hz frequency range, 1g acceleration (sine wave), 30 minutes of continuous testing per axis

Product Performance

High speed control accuracy: The steady-state speed control accuracy is ±0.2% of the rated speed, and the speed deviation is ≤0.5% when the load fluctuates (±20% rated load), which can meet the strict requirements for speed stability of generator sets and industrial power equipment.

Fast response speed: The speed step response time is ≤500ms (from 80% to 100% rated speed), which can quickly suppress speed fluctuations caused by sudden load changes and avoid the risk of engine stalling or overspeed.

Reliable fault protection: Integrates multiple protections such as overspeed, low oil pressure and high water temperature, with a fault response time ≤100ms. It also supports fault record storage (≥50 fault logs) to facilitate post-event troubleshooting.

Strong compatibility: Supports both magnetoelectric and Hall-type speed sensors, adapts to engines with different fuels such as diesel and gas, and the analog input can be customized to associate with protection logic, adapting to diverse application scenarios.

Excellent environmental adaptability: The -40℃ to +70℃ wide temperature design covers alpine and high-temperature areas; the IP65 protection rating can resist dust and spray water intrusion, suitable for harsh environments such as outdoor generator sets and ship engine rooms.
