Aka Voltage Tester 6V-400V Electricians Da DIYers Don Yi Maimaita AC/DC Voltage

Bayanan

UT22B-EU voltage tester shine daidai na wurin da electricians da kuma DIYers ke yi amfani da shi wajen bincike AC/DC voltage. Wannan voltage tester yana da rating IP54, kuma an samun shi don taka ƙoƙari daga biyu mita. Abubuwan da ya fi kyauwa waɗanda ba su zama da buƙata, domin voltage da aka bincika ya haifar da shi! UT22B zai iya faɗinsu da AC zuwa DC voltage, ta haka da cikakken LED lights.

Yadda input protection circuitry a cikin voltage tester ya haifar?

• Overcurrent Protection: Idan input current yake da tsawon rated value of the fuse ko current-limiting resistor, fuse zai fitar da ko current-limiting resistor zai iya ƙara current, don hana da damage to the tester from overcurrent.

• Overvoltage Protection: Clamping diodes and Transient Voltage Suppression (TVS) diodes zai iya canza ta hanyar sauƙi idan voltage yake da tsawon certain threshold, absorbing or diverting excess voltage energy to protect the internal circuitry from damage.

• Electrical Isolation: An isolation transformer zai iya electrically isolate the input signal from the internal circuitry of the tester, preventing high voltage from directly entering the tester, causing damage or posing a threat to personal safety.

• Filtering: Capacitors zai iya filter out high-frequency noise from the input signal, preventing this noise from interfering with the normal operation of the tester.

• Comprehensive Protection: Input protection circuits typically employ a combination of the above components and technologies, forming a multi-layered protection mechanism to ensure that the tester can operate safely under various adverse conditions.
