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.

SONOFF MINI-D Smart WiFi Matter Switch (AC/DC 12-48V, dry contact)The SONOFF MINI-D is a compact WiFi switch with a potential-free contact that allows you to control a variety of smart home devices. Thanks to its compatibility with the Matter standard, it works with popular smart home ecosystems such as Google Home, Apple Home and Amazon Alexa, providing convenient control and wide compatibility. The module supports AC 100-240V (0.1A) or DC 12-48V (1A), making it ideal for automating low-voltage systems such as garage doors, heating systems, valve control or controlling large loads via contactors. Built-in 2.4GHz WiFi (IEEE 802.11 b/g/n) and an advanced ESP32 chip guarantee stable communication and responsiveness.Matter compatibilityThe SONOFF MINI-D switch supports the Matter standard, so it seamlessly integrates with major smart home systems such as Google Home, Apple Home and Amazon Alexa. As a result, you can conveniently manage your devices regardless of your preferred platform. The ability to integrate with Home Assistant further enhances functionality. The device also supports schedules and automation scenarios. With the timer function, for example, it is possible to set automatic shutdown of devices at a specific time, which increases safety and energy savings. Additional convenience is provided by the group control function.Greater control flexibilityThe potential-free contact with which the switch is equipped allows you to control devices that require a circuit open/close signal without applying voltage. This makes the module applicable in a wide range of situations - from control of garage doors and heating systems to control of valves or electric locks. Electrical isolation of the circuit provides greater safety and eliminates the risk of damage to the controlled devices.Many possibilitiesThe device supports both alternating voltage (AC) and direct voltage (DC) in the range of 12-48V (1A) or 100-240V AC (0.1A), which allows integration with various control systems. The module's ability to be powered by both home installation and low-voltage power supplies makes the SONOFF MINI-D an ideal choice for professional building and industrial automation installations.Control from anywhereOne of the main applications of the MINI-D is remote control of garage doors. When integrated with a smart home app, you can open and close the gate from anywhere for convenience and security. Combining the switch with a monitoring camera allows you to check the status of the gate in real time, minimizing the risk of leaving it open.Integration with heating systemsMINI-D also works with boiler, thermostat or radiator management systems, so it also proves its worth in intelligent heating control. The ability to program schedules and remote control allows better control of the temperature in the house, reducing energy consumption and lowering heating bills. The module can also work within automation scenarios, such as turning on the heating only when needed.Controlling large loadsA relay with low current consumption (2A) can be used to control larger loads by connecting to a contactor. In practice, this means the module can manage systems with high energy consumption, such as pumps, HVAC systems, industrial lighting or high-powered electrical equipment, while ensuring safe and energy-efficient operation.Automation of valves and irrigation systemsThe MINI-D module can also control solenoid valves and motors up to 8W, so it is ideal for automating irrigation systems. The ability to program schedules allows you to save water and take care of efficient watering of the garden or farm field, which increases comfort and minimizes operating costs.
