40A 220V Din Rail Dual Display Adjustable Over Voltage Current and Under Voltage Protective Device Protector Relay
Descriptions:
• Dual Display :The product features two displays that show the voltage and current levels, making it easy to monitor the circuit's health.
• Adjustable :The device can be adjusted to protect against overvoltage, undervoltage, and other issues, ensuring that your circuit is safe and reliable.
• Protective Device :This product is designed to protect your circuit from damage caused by power fluctuations, ensuring that your equipment stays safe and functional.
• Relay :The relay feature of this product allows you to control the flow of power to your circuit, making it easy to troubleshoot and fix any issues.
Function:
Overvoltage protection
Undervoltage protection
Overcurrent protection
Continuous overcurrent counting
Wide voltage: overvoltage of 130-300V, undervoltage of 80-210V, always in protection mode when not set properly, fault light on
Fast protection for power failure: Abnormal ignition, power failure, and other protective device actions in the front-end power grid
Manual/Automatic Recovery: After manually protecting the output, it must be manually turned on.
When the protection function is turned off, the relay remains in its original state without any further action, but the switch button is still valid
Multi mode display: Switching between voltage, current, frequency, visible power, etc. according to the mode
Set lock: to prevent accidental modification of parameters
DC mode: When DC is used, the current/power is invalid
Energy saving mode: When the protector is not active, reduce the brightness of the digital tube to save energy
Embedded RTOS: improves system performance and stability, with high maintainability
