Siemens 6EP1333-4BA00 SIMATIC PM 1507 24V/8A S7-1500 Power Supply

The Siemens SIMATIC PM 1507 (6EP1333-4BA00) is a stabilized power module purpose-built for the S7-1500 rail, converting 120/230 V AC input to a regulated 24 V DC / 8 A output. It reaches 90% efficiency, tolerates a 62 A inrush current, and carries CE, UKCA, and EAC approvals in an IP20 enclosure without Ex approval.

Selection Notes

At 8 A / 192 W this is the higher-current step in the S7-1500 power module lineup, sized for racks with several I/O modules or when the CPU's backplane load leaves little margin on a smaller supply. The 120/230 V automatic range-selection input removes the manual voltage-tap step some earlier power supply generations required. Two units can be paralleled per the datasheet where a single PM 1507 does not cover the rack's total current draw. Vertical mounting derates the operating temperature range to 0-40°C versus 0-60°C horizontal, which is worth checking against the cabinet's planned orientation before specifying enclosure cooling.

Applications

24 V DC bus supply for SIMATIC S7-1500 racks with multiple I/O, communication, or technology modules where the CPU's backplane current draw exceeds what a smaller PM module or the CPU's integrated supply can deliver.
