The ENTRASYS STK-RPS-150PS is a 150-watt DC redundant power supply that can be used as a standalone unit or installed in a 2-slot (STK-RPS-150CH2) or 8-slot (STK-RPS-150CH8) chassis. It is designed to provide backup power to compatible Enterasys or Extreme Networks stackable or standalone fixed switches that do not support Power over Ethernet (PoE). The power supply continuously monitors the switch's internal power supply and automatically provides power in the event of an interruption to prevent network downtime.

Input Operating Voltages: Typically 90V AC to 264V AC, 50/60 Hz factory grids.

Output Power Capacity: Delivers 150 Watts of continuous regulated DC power to the connected host switches.

Maximum Output Currents: Delivers isolated stable currents across multiple rails, typically providing up to 12.5 Amperes at +12V DC.

Operating Ambient Temperatures: Designed to perform flawlessly under typical plant and server cabinet thermal windows ranging from 0 °C to +50 °C.

Relative Humidity Tolerance: Built to function reliably in environments handling 5% to 95% relative humidity, non-condensing.

Redundant Switching Infrastructure Backup:

Multi-Slot High-Density Deployments:

Harsh Industrial Communication Nodes:

Providing reliable power failover support for stackable edge switches to ensure uninterrupted automated data routing.

Easily scaled in large environments by slotting up to eight modules into an STK-RPS-150CH8 shelf for centralized network protection.

Deployed in control cabinets where network switch uptime is critical for tracking live sensor data and preventing plant-wide communication drops.
