Vertiv

Vertiv SN Temperature Humidity Sensor Modular

SKU CH-VMVC-STWRT

Modular temperature and humidity probe for Vertiv MPX and MPH rack PDUs, operating from 41°F to 131°F and 10% to 95% relative humidity

  • Monitors rack temperature and humidity with a single modular probe
  • Connects directly to Vertiv MPX and MPH rack PDUs via RPC or IS-UNITY-DP card
  • Draws power through the communications cable for simplified installation
  • Mounts securely using the supplied bracket or cable tie
  • Operates reliably from 41°F to 131°F and 10 to 95% relative humidity

Modular Temperature and Humidity Probe

The Vertiv SN sensor is a single modular probe that measures temperature and relative humidity inside a rack. It connects to Vertiv MPX or MPH rack PDUs equipped with an RPC card or a Liebert IS-UNITY-DP communications card. The unit draws power through the communications cable so no separate supply is needed. It is intended for data-centre and network-closet operators who need continuous environmental visibility.

Verify Rack PDU and Communications Card

Before ordering confirm that the target rack PDU is a Vertiv MPX or MPH model and that it has an RPC card or Liebert IS-UNITY-DP communications card installed. The sensor plugs directly into that card; without the correct card the probe cannot communicate or receive power. Ensure the rack environment stays within the 41°F to 131°F and 10% to 95% relative humidity operating range.

Mounting and Cabling in the Rack

The probe ships with a bracket and cable tie for flexible mounting on rails or cable management bars. Its compact 1.6 by .8 inch footprint fits in tight spaces between equipment. Because power and data share the communications cable, only one cable run is required back to the PDU, freeing rack space and reducing cable clutter. The sensor adds roughly 4 ounces to the rack load.

Questions about this item

What comes in the box and what must be purchased separately?

The sensor ships with a mounting bracket and cable tie for installation. It draws power through the communications cable that connects to a Vertiv MPX or MPH rack PDU equipped with an RPC card or Liebert IS-UNITY-DP card; those PDUs and cards are sold separately.

Which version of the Liebert SN sensor should I choose for temperature and humidity monitoring?

This modular probe is the single temperature-and-humidity model in the Liebert SN range. Select it when you need both readings from one device; other SN models cover different measurement types.

What do the operating-range figures mean once the sensor is installed in a rack?

The probe will reliably report temperatures from 41°F to 131°F and relative humidity from 10% to 95% inside the rack, provided the connected PDU and RPC or IS-UNITY-DP card are functioning.
