he ZUMMESH-JBOX-PSU is an accessory power supply that mounts to a four inch square junction box and provides a host for a Zūm® Network Bridge (ZUMMESH-NETBRIDGE [1]) or Zūm Contact Closure Output (ZUMMESH-CCO [1]). It communicates wirelessly with other Zūm Mesh devices in a Zūm commercial room lighting system to enable centralized monitoring and management using the network bridge, or to enable integration with an HVAC system using the contact closure output.

The ZUMMESH-JBOX-PSU is similar to a ZUMMESH-JBOX load controller, but without any dimming or switch circuitry onboard.
