Notices
● Confirm the wind power system voltage matches 690Vac(50Hz) before installation.
● Use wiring with cross-sectional area 2.5mm²-32mm² and tighten screws to 5N·m torque.
● Regularly check the indication window—replace the product immediately if it turns red (failure status).
● Ensure the grounding system meets wind power industry requirements (ground resistance ≤4Ω).
● The product is designed for indoor use in wind turbine control cabinets; avoid outdoor exposure.
● Select the appropriate model based on the required discharge current (40kA/50kA).
FAQ
Q1: What is the maximum continuous operating voltage of this product?
A1: The maximum continuous operating voltage (Uc) is 760Vac, suitable for 690Vac wind power systems.
Q2: Can it be used in solar power systems?
A2: No, this model is designed for high-voltage AC wind power systems. For solar PV systems, choose LPM PV series DC SPDs.
