Why Engineers Specify This Model
- Wide-range AC input – Single SKU covers 100–240 VAC globally, eliminating region-specific variants in multi-site projects.
- Active PFC – Reduces harmonic distortion on plant power networks, protecting sensitive instrumentation.
- Parallel & redundancy capability – Supports N+1 redundant configurations via optional decoupling diode modules, critical for 24/7 process lines.
- Compact DIN-rail footprint – Maximises usable panel space in retrofit and brownfield projects where cabinet real estate is limited.
- Murrelektronik MPS pedigree – The MPS series is a proven platform deployed in tens of thousands of installations across automotive, food & beverage, and semiconductor fabs worldwide.
- Diagnostic output – Integrated DC-OK relay/signal output enables PLC-level fault detection without additional monitoring relays.

Application-Specific FAQ
Q: Can the 857833 power a Siemens S7-1200 PLC and its expansion modules simultaneously?
A: Yes. The MPS series provides sufficient current capacity for a typical S7-1200 CPU plus SM expansion modules. Verify total load current against the rated output current on the datasheet.
Q: Is this power supply suitable for use in a Zone 2 hazardous area?
A: The 857833 is rated IP20 and is not intrinsically safe. It must be installed in a purged/pressurised enclosure (Ex p) or located in the safe area with appropriate barriers for Zone 2 applications.
Q: Can two 857833 units be paralleled for higher current output?
A: Parallel operation is supported using Murrelektronik’s dedicated decoupling diode module to prevent reverse current flow. Contact us for the correct decoupling module part number.
Q: What is the typical MTBF for the MPS series?
A: Murrelektronik publishes MTBF data in the official MPS datasheet. Contact support@konmask.com to receive the full technical documentation.
Q: Do you offer warranty on this product?
A: Yes. Konmask.com provides a 12-month warranty against manufacturing defects. Warranty claims are processed within 5 business days.
