Tripp Lite 3U Temperature Sensor with Dual 12V Fans & LCD Display

The Tripp Lite SRFAN3UTEMP is a 3U panel that brings active cooling and precise temperature monitoring to any standard 19-inch rack. It combines two 12-volt fans with a digital sensor, so heat pockets get cleared out before they threaten servers, switches, or audio equipment.

This panel belongs in small business data rooms, network closets, production studios, or even a home lab. Wherever gear runs nonstop, steady airflow helps prevent thermal shutdowns and extends hardware life. The fans move up to 202.6 cubic feet of air each minute while keeping noise at a modest 42 dB, a level that blends smoothly into most work environments.

The detachable probe measures temperatures from -58 °F to 302 °F (-50 °C to 150 °C) and can sit up to six feet inside the rack, so you can check hotspots near the top, middle, or rear of your equipment stack. A front LCD shows readings in either Fahrenheit or Celsius, and simple buttons let you toggle units or turn the panel on and off with a quick tap.

Installation takes only a few screws. Once in place, you plug the six-foot power cord into any standard 120-volt outlet, PDU, or UPS with an NEMA 1-15P socket. The steel housing, finished in a black powder coat, blends with typical rack hardware and closes off three rack units that might otherwise leak conditioned air.

The panel is RoHS compliant and covered by a two-year limited warranty, giving peace of mind along with cooler, more reliable gear.
