The FH31L-100 relay is particularly suitable for:
Smart meters and energy management systems
Automatic Meter Reading (AMR) systems
Prepaid meters
Remote control switching devices
Power control devices that require low-power hold
Energy saving and environmental protection: the magnetic hold design requires power only when switching, and the hold state does not consume power.
High reliability: dust-proof structure design and strong oxidation resistance of contact materials.
Convenient installation: pin + screw terminal (XB) hybrid connection, support automated installation
Flexible customization: Manganese copper shunt, transformer and other accessories can be provided according to customers' requirements.
Compatible with IEC62052-31:2005 UC3 standard.
Recommended driving voltage is 1~1.5 times of rated voltage, pulse width ≥100ms.
Avoid energizing the “ON” and “OFF” coils at the same time, and avoid prolonged energization (more than 1 minute).
Load terminals are not suitable for reflow, wave or tin soldering, spot soldering is recommended.
The state of the relay may be changed during transportation or installation, please reset it as needed before use.
Avoid dropping the product or being affected by external force to maintain the initial performance parameters.
