Voltage converter PN-3V

Voltage Converter PN-3V provides the ability to connect an external power source to the devices "Strelets-PRO", which have connectors for CR123A battery. Power is supplied from a DC source with a voltage of 9-27 B. At the output of the PU-3V provides a voltage of 3 - 3.3 V, which is similar to the voltage of an unused CR123A lithium battery.

The PU-3V has an input to control the mains voltage of the external source. When the mains supply of the external source is switched off, the output voltage of the PU-3V is reduced to the value of 2.6 V. In this case, the Strelets-PRO device performance is preserved, but the console receives a notification of power supply failure.
