Product Description

A high-power single-phase 24V DC power supply built for large control cabinets, the SITOP PSU8200 6EP3337-8SB00-0AY0 delivers 40A continuous with ample headroom for motor starts and capacitive loads.

Extra Power and Overload Flexibility

Delivers 150% rated current for 5 seconds every minute — ideal for loads with high inrush. A DIP switch toggles between constant-current mode for reactive loads and latching shutdown for applications where sustained overcurrent indicates a fault. Short-circuit current peaks at 120A for 25ms to selectively trip downstream circuit breakers.

Parallel Operation for Redundancy

Two units connect in parallel for 80A total output, with a dedicated parallel mode that adjusts the output characteristic for equal current sharing. Relay contact signals DC OK status, while separate LED indicators show normal operation, overload warning, and latching shutdown.

Worldwide Deployment Ready

Auto-ranging input accepts 85–264V AC covering all global single-phase mains voltages. DNV GL and ABS marine approvals plus ATEX/IECEx certification for Zone 2 hazardous areas make this PSU suitable for offshore, process plants, and factory automation worldwide.
