Power Protector is a multifunctional three-wire power supply system or three-phase electrical equipment monitoring and protection instruments. Set three-phase voltage display, over-voltage protection, undervoltage protection, lack of phase protection (phase-break protection), three-phase voltage imbalance protection, phase sequence protection (the wrong phase protection) in one. can be used to monitor the three-phase power supply of the important parameters (voltage, phase, phase, phase equilibrium), Power Surge Protector the three-phase supply may endanger the power system and equipment safe and reliable operation of the abnormal situation, the timely issuance of alarm signals, so that the control system can be more damaged machinery equipment before the appropriate treatment So that the machine equipment and system to maximize the protection, improve the effectiveness of machinery, equipment and systems, Power Surge Protector reduce the three-phase system failure caused by maintenance costs and maintenance time.
The Power Protector uses the powerful microprocessor and the nonvolatile storage technology, the display uses the high clear ultra wide temperature Chinese liquid crystal, has the function to be complete, the performance is stable, the display is intuitive, the operation is simple, and has the sound and light alarm function characteristic. The Power Protector uses the powerful microprocessor and the nonvolatile storage technology, Power Surge Protector the display uses the high clear ultra wide temperature Chinese liquid crystal, has the function to be complete, the performance is stable, the display is intuitive, the operation is simple, and has the sound and light alarm function characteristic.
The Power Protector uses the panel type installment, the elegant, the bright appearance, Power Surge Protector for the Low-voltage electric control installment enhancement grade.
Power Protector (also known as three-phase power monitor, phase-sequence protector, over-voltage protector, etc.) is mainly used for AC Hz, rated voltage below 660V, industrial three-phase 100V, 220V, 380V (400V), 440V (460V), 660V and other voltage-level fault detection, The voltage of three-phase input power is too high, low voltage, phase break, the wrong phase (reverse phase sequence), three-phase voltage imbalance and so on provide relay protection, can be widely used in power distribution cabinets, distribution boxes, electronic control boxes, Power Surge Protector power electronics devices, telecommunications communication room power supply, etc., is the industrial equipment operation maintenance equipment operating voltage of normal and indispensable protection products.
Main features of Power Protector Products:
High-precision: the use of powerful microprocessors, especially the use of AC sampling technology, voltage measurement accuracy of ± 0.5%, can display three-phase power line voltage value, equivalent to three-phase voltage meter function. Full-featured: With three-phase voltage display, over-voltage protection, undervoltage protection, lack of phase protection (phase-break protection), three-phase voltage imbalance protection, phase sequence protection (wrong phase protection), sound and light alarm in one.
High reliability: The use of a unique three-phase power supply technology, even in the very low voltage, even in the absence of phase, can ensure that the protection, alarm, display the function of normal work. Humanization: All protection function can choose to open (on) or close (off), and can set the action threshold value and action time, user-friendly according to the actual need to adjust flexibly. You can also set parameter viewing and modification when you are working properly.
Intuitive display: The use of special large, wide temperature, Power Surge Protector high-definition Chinese LCD display, the normal operation of the three-phase power supply line voltage value, the failure of the direct display of the cause of the fault, and can also show which phase of the fault, Power Surge Protector as well as the failure of the voltage value, easy to determine the cause of
Fault indication: Fault status detected but not to take off time, fault indication Fuchangliang, backlight flashing, tripping action after the fault indicator flashing, backlight long bright, and the buzzer issued intermittent alarm sound.
Failure record: The use of nonvolatile storage technology, when the occurrence of overpressure, undervoltage, lack of phase, imbalance, reverse phase sequence fault record fault, Power Surge Protector even if the product completely power off can also remember the fault information, convenient trouble inquiry. Can memory the last three times the fault information, has the black box function, facilitates after the accident Analysis breakdown reason, facilitates eliminates the breakdown.
Installation: The use of 96X96 standard size panel, user-friendly construction and installation.
