Product Description
A high-power 3-phase 24V DC supply for large automation systems, the SITOP PSU8200 6EP3437-8SB00-0AY0 provides 40A continuous with the overload handling and protection flexibility demanded by production-critical equipment.
960W from a Compact 3-Phase Design
Drawing balanced current from a 400–500V AC 3-phase supply, this unit delivers 40A at 24V DC for powering entire control systems: large PLCs, multiple HMI stations, dozens of I/O modules, and field devices across a machine or production cell. The wide 320–575V input range handles voltage variations without derating.
Configurable Overload Response
Select between constant-current mode — supplying 60A during overload with gradual voltage reduction that allows the load to stabilize — and latching shutdown for applications where sustained overcurrent must trigger immediate disconnection. 150% extra power (60A) for 5 seconds per minute handles motor and contactor inrush.
Redundancy-Ready Architecture
Two units operate in parallel with a dedicated characteristic curve ensuring balanced current sharing. Combined with a SITOP redundancy module, this creates a redundant 40A power system where either PSU can carry the full load if the other fails.
