▍Coil Data
| Coil Voltage | Pickup Voltage | Dropout Voltage | AVG.Holding Current | Holding Power |
| 12VDC | 9VDC Max | 1.2VDC Min | 0.5A Approx | 6W Max |
| 24VDC | 18VDC Max | 2.4VDC Min | 0.25A Approx | 6W Max |
| 48VDC | 36VDC Max | 4.8VDC Min |
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.
