Description

About the PSU8200

Siemens 6EP3337-8SB00-0AY0 is a SITOP PSU8200 stabilized power supply that converts 120/230 V AC input into a regulated 24 V DC output rated at 40 A (960 W), with output voltage adjustable from 24 to 28 V via potentiometer. It provides galvanic isolation, short-circuit protection, and 25 ms buffering on mains loss.

Selection Notes

The 40 A / 960 W rating and adjustable 24-28 V output place this near the top of the PSU8200 power range for a single unit; two units can be paralleled to raise available power further, which matters when a cabinet's DC bus needs headroom beyond 960 W without moving to a different frame size. The 25 ms buffering time and SELV isolation make it appropriate as the primary 24 V bus feed for PLC and I/O loads rather than a battery-backed branch, since no energy storage is built into the unit itself.

Applications

Primary 24 V DC bus supply for automation cabinets with high load current such as drives, I/O racks, and relay banks; marine and offshore panels covered by ABS/DNV shipbuilding approval; and parallel-redundant power architectures for critical 24 V loads.
