PCB has Low microphone amplifier and audio echo processor. Supported electret and dynamic microphones
Many electronic devices operate in conditions where the fan rotates at idle, and create a constant, annoying noise, accelerating the wear of the fans. The function of this thermocontroller is to reduce the noise from the constantly-running fans by stopping them until the temperature exceeds a predetermined threshold. The module can be used in computer system units, in power units, and any other electronic devices that use cooling with fans. The proposed thermal controller works with 12V or 24V fans, in the start-stop mode, with a hysteresis of 2-5 ° C.
The device has a maximum output voltage of approximately 100 volts – 30 V DC and 3 Amp, which is ideal for your radio laboratory. Using the additional regulator, you can set any output voltage value up to 30 V. The device effectively controls the output flow. This function ensures the ability to cut off strings during short circuits and over-the-air conditions. A visual LED indicator is provided as soon as the set value has been moved.
Technical Specification
Optical switch for cabinets etc.
Turns on the lighting when the cabinet door is opened and turns it off when the cabinet door is closed.
For closed structures such as for lighting cabinets, wardrobes, drawers.
Designed for creating LED lamps using LED strips or rulers and aluminum profiles. The sensor is mounted directly into the profile. The principle of operation of the sensors is based on the reflection of the infrared (IR) rays emitted by them from nearby objects at a distance of up to 5 or 10 cm. Thus, waving a hand or opening and closing a cabinet door triggers the sensor.
