PN-3V voltage converter allows you to connect an external power supply source to the CR123A battery connectors of the devices "Strelets-PRO".PN-3V is powered from a DC source with a voltage of 9 - 27V. At the output of PU-3V provides a voltage of 3 - 3.3 V, which is similar to the voltage of unused lithium battery CR123A.PU-3V has an input to control the mains voltage of the external source.
When switching off the mains power supply of the external source, the output voltage of PU-3V decreases to the value of 2,6 V. In this case, the Strelets-PRO device functionality is preserved, but a power supply failure notification is transmitted to the console.
