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 ACobi-WSNM use?
It operates on the open IPv6 Itron RF mesh network (WI-SUN certified, IEEE 802.15.4g) and connects to the Itron CityEdge management platform, so no per light-point gateway is required.
What socket does it plug into?
A standard 3-pin, 5-pin or 7-pin NEMA twist-lock socket (ANSI C136.10 and C136.41). It can be installed on the top or bottom of a luminaire.
What is the power supply requirement?
100-277VAC, 50/60Hz (85-305VAC operational range), with average consumption below 1.5W.
What luminaire interface does it support?
Dual-dimming auto-detect with 1-10V (analog) and DALI-2 (digital), controlling up to 4 individually addressed drivers.
Does it work as a photocell?
Yes. It runs a default Auto-photocell mode to prevent day burning, alongside an onboard astronomical clock and lighting schedules with dimming profiles.
What are the dimensions and weight?
H102.19mm x D86.7mm, weighing 205g, with IK09 and IP66 protection.
What is the warranty period?
10 years from factory, subject to obiWAN Terms and Conditions.
