Severe Environmental Adaptation: Operating Temperature Range -40℃~85℃, Humidity 5%~85%RH
Anti-Interference Design: Excellent Anti-Power Frequency Interference Resistance and Good Consistency
The FH21L-60 Relay is particularly suitable for:
Smart Metering Systems: Precise Control of Power Distribution
New Energy Devices: Solar Power Inverters, Wind Power Generation Systems New energy equipment: solar inverters, wind power generation systems
Composite switching applications: high reliability switching requirements
Smart home systems: DIN-rail mounting solutions
Industrial automation: control circuits with excellent immunity to interference
To ensure optimal performance, it is recommended that the actual drive voltage be 1~1.5 times the rated voltage and the pulse width be ≥50ms
Avoid energising both the "open" and the "closed" coils at the same time
Load terminal is not suitable for reflow soldering or wave soldering. Load terminals are not suitable for reflow, wave or tin soldering, spot soldering is recommended.
Relay status may change during transport or installation, reset as necessary before use.
