FAQs of DS1812:
Q: How does the DS1812 voltage sensing relay protect my equipment?
A: The DS1812 continuously monitors the supply voltage and automatically trips (disconnects) the load if the voltage departs from the safe 150280V AC range, thereby safeguarding equipment from over- or under-voltage damage. It automatically resets when the voltage returns to a safe level.
Q: What is the process for installing the DS1812 in my control panel?
A: Installation is simplemount the DS1812 onto a standard 35mm DIN rail in your panel, connect the input and relay output via the provided screw terminals, and ensure the supply matches the rated 230V AC, 50/60Hz requirements.
Q: Where is the DS1812 typically used?
A: The DS1812 is ideal for use in electrical and control panels, particularly in settings where voltage stability is critical, such as industrial machinery, commercial systems, or sensitive electronic equipment installations.
Q: What benefits does the automatic reset feature offer?
A: The automatic reset ensures continuous protection without manual intervention; after a trip due to voltage anomaly, the relay resets itself when conditions return to normal, reducing downtime and operational inconvenience.
Q: When should the DS1812 be used instead of a conventional relay?
A: Use the DS1812 when you require real-time voltage monitoring with precise trip points and automatic restoration, offering superior protection for sensitive loads compared to standard relays that lack voltage sensing capabilities.
Q: What is the maximum load capacity the DS1812 can handle?
A: The relay is rated for up to 5A resistive load at 230V AC, making it suitable for most control or protection circuit applications without exceeding its operational limits.
Q: What operating conditions is the DS1812 designed for?
A: The DS1812 functions reliably in environments with 095% RH humidity (non-condensing) and temperatures from -10C to +55C, ensuring dependable performance across diverse industrial and commercial settings.
