| ◆ transmission unit |
| Use power |
AC100V ± 10% 50 / 60Hz |
| Primary current CT |
5/10/15/20/25/30/40/50/60/75 / 80A |
| Corresponding pulse |
50000 pulse composite power meter (CT pulse output type) |
| Power conversion method |
Min 15 (45) of every hour, from 20 (50) minutes to 30 (60) minutes pulse count that has been accumulated in every minute until, and in terms of the respective data to the predicted value of 30 minutes. |
| Power comparison method |
Each installed capacity set value 50000 pulses (maximum), to calculate the number of pulses of the alarm power setting.
Alarm power pulse number = alarm power setting ÷ installed capacity set value × 50000
Note output pulse number = alarm power pulse number × 0.8 |

| Power failure compensation |
Compensation in the lithium-ion battery |
| Clock Set |
In the lamp lighting of five minutes will do the setting. |
