Frequently Asked Questions
Q1: Can all 24 5A channels operate at full load simultaneously?
Yes. All 24 channels can provide a total current of 120A when fully loaded simultaneously. At 440V, the theoretical transmission power reaches 52.8kW. Ensure proper power supply capacity and heat dissipation conditions in practical applications.
Q2: What are the advantages of precious metal contacts compared to ordinary gold plating?
Precious metal contacts (gold-based or silver-based alloys) offer superior wear resistance, stable contact resistance over long periods, stronger resistance to oxidation and sulfidation, and excellent performance for weak signal transmission including thermocouples and strain gauges.
Q3: Is 440V suitable for common 380V industrial power grids?
Absolutely. The 440V rated maximum voltage ensures safe operation in systems with various voltage levels including 380V, 400V, 415V, and 440V, providing strong compatibility.
Q4: What are the specific dimensions of the hollow via? Can it be customized?
Standard model via inner diameters include common sizes such as 12.7mm, 25.4mm, 38.1mm, and 50mm. We provide custom designs for non-standard large diameter vias up to several hundred millimeters.
Q5: What is the expected lifespan of the product at 250rpm?
Under rated load, standard environment, and proper installation, slip rings with precious metal contacts typically exceed 50 million revolutions. Actual lifespan depends on current magnitude, ambient temperature, and installation concentricity.
Q6: Does it support mixed signal and power transmission? How to avoid interference?
Yes. All channels are electrically independent and can be allocated as needed. For sensitive signals, we recommend: physical isolation of signal channels from high-current channels, using twisted-pair shielded cables, ensuring proper system grounding, and offering customizable independent shielded versions for signal channels.
