20/24 4/6/8 Pin Computer PC Power Supply Tester with LCD Display and Buzzer for ATX, ITX, BTX, PCI E, SATA, HDD

  • ...en your power supply test value is beyond normal range, the Power Supply Tester would issue a buzzer alarm, Easy to Know..
  • WITH LED DISPLAY: We have developed a portable computer power tester for the power supply market that can judge the quality of the power supply. It has LCD display intuitive and accurate display voltage (+/ 0.01V), automatic fault alarm, complete test interface, small and beautiful appearance, and more test functions. It is your best choice and reliable helper to quickly detect PC power..
  • EASY TO USE: This power tester only needs to be connected to the power supply ATX connector to easily and intuitively know whether the output of each power supply is normal. It can detect ATX, BTX, ITX, TFX computer power supply, and can display various voltage and PG values in LCD screen to quickly detect the performance of computer power supply..
  • PRACTICAL & CONVENIENCE: Small and practical power tester. Now the number of power output groups is increasing. As long as one of them has problem, the hardware of the computer system may work abnormally or even burn out. To measure whether the output voltage output of the power supply is stable, the player usually uses a multimeter. But for the average user is still a little troublesome..

Siemens 3UG4631-1AW30 Monitoring Relay, Single Phase Voltage Monitoring, Screw Terminal, 1 CO Contacts, 0.1-60VAC/DC Measuring Range, 0.1-30V Hysteresis, 0-20s Delay Time, 24-240VAC/DC Auxiliary Voltage

  • 3 INDICATORS-The protector base adopts 35mm rail type or device type, and has two screw hole structures inside, which can be directly installed separately or HT35 rail. Indicated by three indicators: normal, phase loss(voltage three-phase unbalance), reverse phase.
  • PHASE LOSS PROTECTION-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.
  • REVERSE PHASE PROTECTION-Reverse phase protection, a protection measure to prevent L1, L2, L3 three-phase AC phase sequence from being connected incorrectly, delay 2S action.
  • VOLTAGE IMBALANCE PROTECTION-Voltage imbalance protection, which refers to a protective measure that will affect the safe operation of the line due to three-phase voltage imbalance.
  • IDEAL FOR-Widely used in air compressors, electric motors, distribution boxes, water pumps, oil pumps, central air conditioning units, etc.
