A practical evidence checklist for RFQ preparation and supplier evaluation.
Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
1 company lists this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
The input voltage range is specified as 3–30 V DC. However, this is a reference range; the actual operating range may vary by model. Always verify with the manufacturer's datasheet for the specific part.
It continuously compares the measured circuit voltage against predefined thresholds. If the voltage deviates beyond acceptable limits, indicating events like short-circuiting or power interruption, it triggers an alert signal to the control system.
The output is open-collector, active low, requiring a pull-up resistor. It can sink 10–50 mA. This allows connection to digital inputs of microcontrollers or logic circuits.
The operating temperature range is -40 to 85°C, and storage temperature is -55 to 125°C. Ingress protection ranges from IP40 to IP67 depending on housing. Confirm the specific rating for your chosen model.
