Pulsar PSB-48V3A built-in buffer power supply 48V 3A

Pulsar PSB-48V3A built-in buffer power supply 48V 3A

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 48 V DC.
The power supply provides voltage U=54V DC with current efficiency:

• output current 2.5A + 0.5A battery charge
• output current 2A + 1A battery charge

The total current of receivers + battery is max. 3A.
In the event of a mains voltage failure, it immediately switches to battery powered
Passive cooling, free air circulation.
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)
• battery charging current 0.5A/1A, jumper switchable
• protection of the battery output against short circuit and reverse connection
• passive 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
