General Description: The Power Supply System type PSS1250 is an anodized aluminum

19” Rack unit (4U high) suitable to accept up to 6 plug-in Power Supply Modules type

PSM1250 and 1 Overview module for diagnostic functions. Each module provides 24Vdc,

50 A output. Modules can be paralleled with load sharing circuits which distribute current

load equally to each power supply module to increase reliability and reduce internal power

dissipation. The system accepts up to two independent AC power sources with nominal

voltage range 110 to 240 Vac (±10). Sixteen configurations of 19” Rack Units are

available with or without Hot Swapping: eight for wall mounting and eight for frontal rack

mounting, always into a cabinet. Two configurations of 9” Rack Units are available with or

without Hot Swapping, only for wall mounting into a cabinet. Two configurations of 7” Rack

Units are available with or without Hot Swapping, only for wall mounting into a cabinet.

For more information about different configurations see page 2.
