JBF - PWMS Power Monitoring System Diagram

Introduction of JBF-PWMS Power Status Monitor

JBF-PWMS power status monitor (hereinafter referred to as the monitor) is a wall-mounted single-loop monitoring device, which simultaneously monitors 252 field voltage and/or current type sensors. When the sensor detects interruption of power supply, overvoltage, under-voltage, lack of phase, fault phase, overload, and such power failure, it gives out sound and light signals, and records the type, location and time of the fault occurring device, reminding the personnel on duty to troubleshoot in time.

Composition of the Monitor

Monitor mainly includes: a control panel with 7 "LCD (JBF-61S60DP), a single loop board (JBF-61S60LA), a dual output fire power (DC27V / 140 w) with backup management feature, and a set of batteries (7AH / 12V).

Power State Monitoring and Failure Alarm.

(1) overvoltage fault alarm: the voltage value of the monitored power supply is greater than 110% of the rated voltage;
(2) under-voltage fault alarm: the voltage value of the monitored power supply is less than 85% of the rated voltage;
(3) power supply interruption fault alarm: the voltage value of the monitored power supply is 0V or the connection with the sensor is lost;
(4) fault phase alarm: the sequence of A, B and C of the connected sensor is inconsistent with the sequence of A, B and C of the monitored loop;
(5) missing phase fault alarm: the three-phase three-wire or three-phase four-wire sensor loses (or disconnects) a line (A, B and C);
(6) themonitor can receive voltage and current signals of the main power supply and standby power collected by sensors in real time. When there is overvoltage, under-voltage, lack of phase, fault phase, power supply interruption, current overload and such power supply failure in the fire protection equipment, the monitor sends out sound and light alarm signalswithin 100s.
