Overview

A4531 is the SY4527 / SY5527 Primary Power Supply block. It includes the SERVICE Power Supply Unit (PSU) and the 600 W PSU for boards in a single slot module. Each SY4527/SY5527 System includes one A4531 Primary Power Supply. In addition to the A4531, the user can add other optional PSU that provide 600 or 1200 watts:

• A4532 – SY4527/SY5527 Optional Single Power Supply Unit 600W
• A4533 – SY4527/SY5527 Optional Double Power Supply Unit 1200W

Note: In SY4527 the max number of PSU which can be installed is 4 (1 Primary and 3 Optional). In case the SY4527 is equipped with LCD display the max number is 2 (1 Primary and 1 Optional). In SY5527 the max number of PSU which can be installed is 2 (1 Primary and 1 Optional).

New! For SY4527 systems with high channel count configurations (more than 650 channels), the A4531B version is available. A4531B is a variant of the Primary Power Supply with a different internal power distribution: it provides reduced power to the +48V (450 W) while delivering increased power (300W) on the +12V rail, which supplies the control and logic sections of HV boards.
All Primary PSU modules (A4531 and A4531B) generate the following output voltages: +5V, +12V, -12V, and +48V, and also provide power to the FAN units of the system.
