Detailed content

Technical Specifications:
  • Power Supply: 88–132 VAC AC input
  • Speed Sensing: Magnetic pickup pulse input
  • Drive Output: Proportional actuator drive
  • Operating Temperature: -40°C to +85°C
  • Humidity: 10%–95% non-condensing
  • Enclosure Rating: IP20
Functional Features:
  • Direct AC power supply, eliminating the need for a DC power conversion module and simplifying the field power supply circuit
  • Supports isochronous mode and droop mode for load balancing across multiple parallel units
  • Hardware circuit self-test with fault status alarm contact signal output
  • External potentiometer for speed and droop parameter setting
  • Compatible with other controllers in the same series to form multi-unit parallel systems
Application Scenarios:​ Industrial plant fixed generator sets, gas turbine auxiliary power generation, land-based distributed power stations.
Material Composition:​ Sheet metal enclosure, industrial-grade multi-layer PCB, flame-retardant terminals, built-in AC power conversion circuit.
Structural Features:​ Cabinet-embedded single-board structure with all terminals arranged on the front of the device; no local display panel.
Working Principle:​ AC power is converted by the internal power module into the internal control circuit power supply. The speed signal is acquired and compared with the set value for calculation, and a drive signal is output to control the actuator. Under parallel operating conditions, it reads the load bus signal to complete load sharing.
Installation Requirements:
  • Install inside a sealed control cabinet, away from high-power interference equipment, with reserved heat dissipation space
  • An independent circuit breaker must be configured in the AC input circuit as a device disconnect means
  • Speed signal lines and load sharing bus must all use shielded twisted-pair cable with the shield grounded at a single point
  • Installation on equipment bodies with severe vibration is prohibited
Usage Precautions:
  • Confirm that the power supply is within the 88–132 VAC range; overvoltage will damage the internal power conversion circuit
  • This controller does not include independent overspeed protection; the system must be equipped with an independent hardware overspeed shutdown device
  • Ensure correct wiring polarity and anti-static protection during board assembly/disassembly
