Pulsar PSB-12V15A enclosed buffer switch mode power supply unit 13.8V 15A

Pulsar PSB-12V15A built-in buffer power supply 13.8V 15A

A buffer power supply with stable parameters, high efficiency and small size dimensions is designed to supply system devices from the 230 V mains alarm systems, monitoring systems and other devices that require constant voltage 12V DC.
The power supply supplies voltage U=13.8 V DC with current efficiency:

• 13A output current + 2A battery charge
• 11A output current + 4A battery charge

The total current of receivers + battery is max. 15 A.
In the event of a power failure, the device immediately switches to battery power
Cooling is done in a forced way, with a built-in fan.
The power supply is equipped with the following protections:

• short-circuit protection SCP
  
• overload OLP
  
• overvoltage OVP
• surge
  

The most important features of the power supply

• wide input voltage range
• battery charging and maintenance control
• protection of the battery against excessive discharge (UVP)
• 2A/4A battery charging current, jumper selectable
• protection of the battery output against short circuit and reverse connection
• forced cooling
• output voltage presence indicator
• casing height: 50mm
• possible optional mounting on a DIN rail by using special ones fasteners
  
• optional equipment: a set of external optical LED signaling PKAZ168, DIN3 mounting plate
