Ratings
| Model | Detected voltage | Load | Setting range | Control output | ||||
| Rated voltage | Power/VA consumption | Must-operate (SET) voltage (percentage of rated value) | Must-release (RESET) voltage (percentage of rated value) | Rated carry current | Switching capacity | |||
| Rated operating voltage | Rated operating current | |||||||
| Resistive load (cosΦ = 1) | Inductive load (cosΦ = 0.4, L/R = 7 ms) | |||||||
| LG2-AB | 100 VAC 200 VAC 50/60 Hz | 5 VA max. | 75% to 120% | 70% to 115% | 5 A | 100 VAC 200 VAC 28 VDC 110 VDC | 5 A 2 A 5 A 0.2 A | 3 A 1.2A 2 A 0.1A |
| 110 VAC 50/60 Hz | 80% to 110% | 75% to 105% | ||||||
| LG2-DB | 12 VDC 24 VDC 48 VDC 100 VDC | 3 W max. | 75% to 120% | 70% to 115% | ||||
Note:
1. Set the must-operate voltage higher than the must-release voltage by at least 5% of the rated value.
2. Smoothing is required for the detected DC voltage.
3. The maximum applied voltage is 120% of the rated value.
4. Special models enabling a rated voltage of 220 V are available. The setting range for these models is 80% to 110%.
