DTP300 Electrical Fire Monitoring

Mainly used in the low-pressure three-phase four-wire system leakage protection and realize the main basic U, I, P, KWH and isoelectric parameter display; LCD display, data turns display and designated show optional; With time memory function, alarm can record 50 fault happen type, time, departure time values, according to the fault record can analyse the reason of failures to provide basis for the elimination of failure.

Use range

1.Apply to all kinds of existing electrical equipment

2.High-rise buildings, fire hazard in places such as crowded conditions of electrical protection

3.Key fire-proof building electrical protection

4.Electrical parameters of time measurement

5.Electrical fire monitoring system

6.Suitable for 380V voltage grade palaces line protection

DTP300 series product main function

◆LCD display, data turns display and specified display can be chosen

◆Has the leakage, temperature, pressure, undervoltage etc. Various protection function

◆To achieve the three-phase voltages, the power supply line, power, the three phasecurrent high-power electric parameters such as electric degrees, the measurement

◆Provide four lk switch input, programmable trigger events, can set with fire smoke sensors, remote signal connection, constitute fire linkage

◆Adopt fieldbus communication technology, PC management software can real-time monitoring each detector. Communication with RS485, this communication system reliability, expansibility, using international standards of Modbus - RTU agreement, can with all sorts of standard power monitoring software connected

◆With time memory function, alarm can record 50 fault happen type, time, triggering time values, according to the fault record can analyse the reason of failures to provide basis for the elimination of failure
