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.

Q3: What is the function of the built-in ultra-low temperature release mechanism?

A3: It ensures the product operates safely in low-temperature environments (-40℃) and disconnects faulty modules to avoid hazards.
