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

Overview

The Tripp Lite SRFAN3UTEMP is a 3U rack panel designed to provide active cooling and accurate temperature monitoring for standard 19-inch equipment racks. It features dual 12-volt fans that deliver up to 202.6 cubic feet per minute of airflow while maintaining a noise level of just 42 dB, helping to prevent overheating in servers, switches, and audio gear. The integrated temperature sensor measures from -58 °F to 302 °F (-50 °C to 150 °C) and can be positioned up to six feet inside the rack to monitor critical hotspots effectively.

Key features

• Dual 12 V fans that efficiently clear heat pockets to maintain optimal operating temperatures for rack equipment
• Temperature probe with flexible placement inside the rack for precise monitoring of different equipment zones
• Front LCD display shows temperature readings in Fahrenheit or Celsius, with easy push-button controls for unit switching and power
• Steel housing with black powder-coated finish that fills unused rack space and enhances airflow management
• Simple installation requiring only a few screws and a six-foot power cord compatible with standard 120 V AC outlets, PDUs, or UPS units
• Quiet operation at 42 dB, making it suitable for office, studio, or home lab environments where noise levels matter
• RoHS compliant design ensuring environmental safety and backed by a two-year limited warranty for reliability
