Get to know this product.

The ZUMMESH-JBOX-PSU is an accessory power supply that mounts to a four inch square junction box and provides a host for a Zum™ Network Bridge (ZUMMESH-NETBRIDGE) or Zum Contact Closure Output (ZUMMESH-CCO). It communicates wirelessly with other Zum Mesh devices in a Zum 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.

*Please refer to the Zum Lighting Control System Setup Guide (Doc # 7957) for additional information.
