The intelligent power safety monitoring device is a combined electrical fire detector that uses segment LCD display and integrates real-time detection of three current signals, one leakage signal, four temperature signals and audible and visual alarm functions. The design, manufacture and inspection of this detector comply with the national standard GB14287-2014, Part 2 and Part 3. It is stable and reliable in operation and flexible in application.
1. One circuit leakage current monitoring. The leakage current alarm value range is 0.1~9.999A.
2. Four way temperature monitoring. Temperature alarm value range: 45~140 ℃.
3. Zero ground voltage monitoring. Zero ground voltage alarm value range: 0.5~10V.
4. One switch output (relay contact).
5. One circuit reclosing relay.
6. Three phase full power monitoring. Voltage, current, frequency, power, power factor, electric energy. Voltage measurement rating: 220/380. It can be overloaded by 1.5 times. Current measurement rating: 50/100/200. Various specifications of current transformer can be selected (external connection of current transformer).
7. Total harmonic of voltage and current (THD), 2~31th harmonic distortion.
8. 128 * 64 dot matrix LCD display.
9. Operation, mute, alarm and fault indicators.
10. Buzzer alarm.
11. Rail mounted.
12. Working voltage: 85~264VAC, 110~375VDC.
