UNI-T UT22B-EU AC/DC voltage tester The UNI-T UT22B-EU voltage tester is a reliable tool created for both electricians and do-it-yourselfers who want simplicity of operation and high precision. The device allows automatic detection of AC/DC voltage and indicates the polarity of DC voltage (+/-), as well as warns of dangerous voltage above 50 V. The UT22B-EU is distinguished by its IP54 rating, resistance to drops from heights of up to 2 meters, and requires no batteries or rechargeable battery - it is powered directly by the measured voltage. The product meets stringent CE and UKCA standards, guaranteeing safe and reliable operation. Automatic voltage detection and user protection Thanks to the automatic AC and DC voltage detection function, working with the UNI-T UT22B-EU tester becomes faster and safer. Built-in LEDs indicate both the presence of voltage and its polarity in the case of DC, allowing for easy and intuitive readings. In addition, the tester is equipped with a special indicator that warns of dangerous voltages exceeding 50 volts, significantly increasing your protection when taking measurements. Rugged design and trouble-free operation The UT22B-EU is designed to operate in harsh environments - the IP54 protection rating protects the device from dust and splashing, and the rugged housing protects it from mechanical damage, even when dropped from a height of 2 meters. No need for batteries or a rechargeable battery eliminates the risk of interruptions, and built-in input protection ensures long equipment life. The UNI-T UT22B-EU voltage tester is an excellent choice for anyone who values reliability, safety and convenience.

LED draiveris samazina ieejas spriegumu no 220-230 V uz 12 V. Pateicoties tam, to var izmantot, lai darbinātu lielāko daļu LED lentu mēbeļu armatūrai. GTV LED draiverim ir īssavienojuma un pārslodzes aizsardzība, kas palielina tā lietošanas drošību. Augsta efektivitāte un ļoti zems enerģijas patēriņš gaidīšanas režīmā ir raksturīgas iezīmes, kas padara to par ļoti ekonomisku risinājumu, kas paredzēts nepārtrauktai darbībai. Kāpēc ir vērts izmantot 24V LED draiveri? Šis risinājums nodrošina daudz mazākus sprieguma kritumus, kas rodas, pagarinot darbināmās LED lentes posmu, un līdz ar to gaismas spilgtumu tās galā. Produktiem, kas izmanto 24V, nepieciešama mazāka strāva nekā 12V, tāpēc tie mazāk uzkarst, un jāatceras, ka gaismas diodes "nemīl" augstas temperatūras.
