YWBL-WH Monitoring Relay,JVRD6 Phase Sequence Protection Relay Monitoring Voltage Control Device

Function: Three-phase monitoring of phase sequence, phase loss..
Application: This monitoring relay is suitable for pumps, fans, blowers, motor elevators, cranes, central air conditioners, etc..
Construction and installation: This phase sequence relay uses standard modular construction and rail-mounted mounting..
Power supply mode: Powered by the measurement circuit, no additional auxiliary power supply is required..
Accessories: With 2 indicators to indicate various working conditions, the two groups usually open/close contacts..

◆ Function: phase sequence detection, live line check, simple performance check, live cable identification, phase loss assessment, search for cable break position, detection of DC line break point, line maintenance.
◆ Non-Contact Inspection: Non-contact inductive measurement of the terminal type without opening the cable, without touching the exposed high voltage fire cable, with the three highly insulated super inductive terminals inserted directly into the cable insulation skin 3-phase live detection for safe and quick productivity..
◆ Positive and Negative Phase: With the LED display, dynamic sound and light perfectly show the positive or negative phase of the phase sequence of the three-phase power supply, which can be seen at a glance..
◆ Magnetic base: The base plate of the instrument is equipped with 4 magnets that can stand a quality of 800 g. They can be attached to the metal case of the device during the test, and it is convenient and convenient to use..
◆ Wide Voltage Test: This phase meter can detect three-phase voltages from 70V to 1000V and has excellent performance..

【Multi-Parameter Measurement】Enter the Smart (Auto) mode by default, the digital multimeter automatically identifies and measures AC/DC Voltage, Resistance, and Continuity. It also tests Capacitance, Diode, Frequency, and Live Wire..
【Phase Sequence 】ST120 stands out with its unique phase sequence detection. When turn on the “PA” mode, the operator can detect whether the phase sequence is clockwise or anti-clockwise..
【Easy to Use】Switch measurement mode with button “Func” and hold data with button “H” . Backlight LCD screen ensures reading to be clearly seen in either dark or bright areas. The flashlight below the red probe helps you to work without concerns under dim light..
【Wide Application】 Industrial electrical safety measurements, household electric problems, vehicle and circuit inspection..
【 Customer Service】Lifelong technical support is guaranteed. Please don’t hesitate to contact us if there are any questions with our ST120 pen-type multimeter..

The base of the protector adopts a rail type with two screw holes, which can be directly installed separately or mounted on the HT35 rail..
Use 5 indicators to indicate: normal, phase loss (voltage three-phase unbalance), reverse phase, overvoltage and undervoltage..
Phase loss protection means that when the protected line is in the running state or non-operating state, any phase failure occurs, and the delay is 2S..
Overvoltage protection means that the voltage of the protected line is higher than the set value, and the delay is 3~8S, and the recovery is 6~20VAC..
Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action..

The Composition of This Product: Three-phase voltage protector, chronograph and counter are integrated in one relay..
Function: This voltage protection relay has overvoltage, undervoltage, phase loss, phase sequence and unbalanced three-phase voltage protection..
Practicality: This 3-phase voltage relay does not require an external power supply. Has practical functions: power delay, output test, etc.
2 rest modules are optional, manual and automatic..
The LCD can display data for easy reading..
