• Link multiple fans together in different configurations.
• Link fans to temperature controlled models so all fans are controlled by temp.
• Link standard fans together so all share a power source.
• Link cabinet fans and rack mount fans together.

When combining fans note the amperage draw of each fan added to the system. Add all of the amp ratings together. The total should be half of the amp rating of the power supply being used. Most systems run on a 1 or 2 amp power supply others up to 6 amp is required.

For standard rack mount fans, connect the power supply to the first fan. This will be the master control. Then connect more fans to the slave fan connector. Slave connectors are standard on SX and SXT series fans. TV series fans can be custom made with slave option.

For temperature-controlled rack fans, connect the power to the controller unit. Then using the PSA-SP Adaptor cable, connect additional standard rack fans.
