Zhaga outdoor lighting controller
Product Overview
DCobi-NBZG is a Low Power Wide Area Cellular Narrow Band DALI-2 outdoor lighting controller, powered directly from a D4i LED driver and is installed on a luminaire using a standard Zhaga Book 18 street lighting connector.
DCobi-NBZG works straight out of the box, connecting directly to the existing cellular network without the need for additional gateways, self-acquiring its GPS location and auto-commissioning into any TALQ compliant Central Management Software. Just like that, with no more complexity to the adoption of massive IoT technology in the urban environments.

Answers to the questions
we’re asked most.
We’re here to help! Our FAQ section provides quick answers to some of the most common inquiries we get on our IT services.
What wireless network does the NB-IoT/LTE-M Zhaga controller use?
It connects directly over the existing cellular network using NB-IoT and LTE-M (3GPP), with no external gateway required — each controller communicates independently with the management platform.
How is it installed?
It mounts externally on a standard Zhaga Book 18 receptacle (push-and-twist lock socket) on the luminaire.
What is the power supply requirement?
24VDC, with an extremely low average power consumption of less than 0.3W.
What luminaire interface does it support?
DALI-2 according to the IEC 62386 standard, compliant with D4i, controlling up to 4 individually addressed drivers.
Does it have onboard GPS?
Yes — an onboard GNSS receiver provides automatic and precise self-location and commissioning.
What are the dimensions and weight?
H41mm (1.61") x D79mm (3.11"), weighing 71g.
What is the warranty period?
10 years, subject to obiWAN Terms & Conditions.
