AVT2857 A +

The AVT2857 module is a universal system that integrates a voltmeter, an ammeter and a thermostat. It can be used in the laboratory power supply to monitor the value of the set voltage and the current consumed. The thermostat, together with the appropriate current limitation, will enable protection against overheating and overloading. This is a great way to modify an existing or self-built power supply. Another practical way to use the module is to adapt it to the charger of various types of batteries used in general-purpose equipment and in modeling. The system monitors the voltage at the terminals of the charged cell and in case of reaching the set value (charge) its disconnection. The thermostat helps to monitor the temperature of the cell - a factor that is extremely important when charging with high currents.

The device is particularly recommended in the home electronics workshop - as a universal module for many applications
