Remarks:
1. The coil parameter values are theoretical values at an ambient temperature of 20℃, with a variation range of approximately ±10% due to the influence of coil resistance.
2. The reliable working voltage range of the coil is 85%~110% of the rated voltage.
3. If other rated voltages are required, special orders can be made.
