12V DC Power Supply Unit BП-12/2A for Security and Fire Alarm Systems

The power supply unit BP-12/2A esp. B (hereinafter - PSU) is designed for power supply of technical means of security and fire alarm system with nominal voltage of 12 V DC. The power supply unit is powered from AC mains 220 V 50 Hz (hereinafter - OIP) or from a battery (hereinafter - the battery) with a voltage of 12 V and a capacity of 7 Ah or 17 Ah.

The PSU is protected against overcurrent and short-circuit (short-circuit) on the output. The PSU provides indication of the state of the power supply unit, the battery and its charging circuits, as well as output voltages via two outputs VYX1 ("AC") and VYX2 ("DC"). The PSU has two power outputs OUTPUT1 and OUTPUT2, which are used to provide dual input power to devices.

Also these outputs can be information outputs of the instrumentation and AB states for external indication and processing by other devices. The PSU also has a generalised fault output for the instrumentation or the battery. Service life of the PSU is not less than 10 years.
