PSU-1205B Uninterrupted Power Supply (PSU-1205B)

PSU-1205B Uninterrupted Power Supply
Introduction:
PSU-1205B power supply is specially designed with adjustable voltage for both DC output and Charger. Furthermore, it has the function of low battery cut off and over-charge protection. This Power Supply is best used for Building Intercom System, Video Phone System, Access Control System and all types of electric locks like electromagnetic lock, bolt and striker.

Advantages
A: Lower Battery Cut Off:
The supply of power will be Cut off when the battery voltage drop at 10.5VDC. This is to prevent the system from running at unstable voltage thus put the system in hanging status.

B: Over-Charge Protection
The charging voltage is adjusted to detect the charging need (when the battery voltage is low) as well as to protect from over-charge (stop charging when it is fully charged)

Specification:
Input: AC 220 to 240V, 60W, 50/60Hz
Output: Set at DC12V (Adjustable from DC12 to 15V) 5A
Charging Voltage: Set at DC14V (Adjustable from DC13 to DC15V)
Dimension: L 250× W 220 × H 80 MM Weight: 2.5KGS without battery
