A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The typical control signal is 4–20 mA, with 0–10 V DC also available. The signal comes from a temperature controller and determines the firing angle.
The operating temperature range is -10 to 50°C, with derating required above 40°C. Storage temperature is -20 to 70°C, and humidity should be 5–95% RH non-condensing.
Protection ratings range from IP20 to IP54 per IEC 60529. IP54 is suitable for harsh environments, but verify the specific model's rating with the manufacturer.
It uses phase-angle control: the firing pulse to the SCRs is delayed relative to the AC zero-crossing, controlling the conduction angle and thus the power delivered to the load.
