ComRent International, LLC, has engineered and launched the CRLS 11.5 kW load bank, a 19-in. rack-mountable load bank, weighing 56 lbs. The new load bank is designed specifically for testing hot aisle containment and cold aisle isolation while providing variable fan speed control, which offers incomparable function and efficiency for data centers.

The 11.5 kW variable fan speed control allows adjustment of airflow, temperature data, and altitude compensation and can be used to adjust the applied load. The unit has two channels with input per channel that can operate at independent voltages and has an adjustment range from 530 cfm to a maximum of 730 cfm per channel.

With three load steps per channel, the load bank allows for five different load combinations, providing a fine load step resolution at all voltages. A channel can be disabled with the master load switch, which prevents the fans for that channel from operating and inhibits the load application for that channel.

Additionally, the fan and control power can be sourced internally or externally. The external fan and control power allows the unit to be used to create a black start condition.

The current draw is 2.6 A at 120VAC with the fan at its maximum setting (internal or external power). At full load, the CRLS 11.5 kW offers: 4,404 W at 120VAC; 8,554 W at 208VAC; 10,576 W at 230VAC; and 11,592 W at 240VAC.

With exceptional functional benefits, the 11.5 measures 9U in height and is supported by front-mounting plates, allowing it to fit easily into traditional server racks and eliminating the need for bracing or temporary shelves.
