girdComm NB-IoT NEMA SLC-N-500-NB Smart Light Controller
Overview
NB-IoT is a low-power WAN (LPWAN) communication technology with promising
prospects. It has been widely used in various fields of the Internet of
Things. It can be seen that the NB-IoT communication module occupies an
important position in the Internet of Things industry.
NB-IoT NEMA Smart Light Controller (SLC) as shown in Fig. 1 is a remote-
control device for HID or LED luminaires equipped with an ANSI C136.41 NEMA
receptacle. The controller connects with a cellular NB-IoT network directly.
This in turn connects with the remote management platform for management and
control as shown in Fig. 2. The controller is exceptionally suitable for
various terrains and environments and comes with a built-in tilt sensor and
Global Positioning System (GPS).
Management Platform
- Built-in standard NB-IoT communication module to realize long-distance transmission, low-power operation, large-capacity networking, and high-reliability communication
- Connects to supporting cellular networks and supports remote control such as on/off, dimming, status monitoring of the streetlight, etc.
- Built-in electric energy metering chip with 1%accuracy
- Built-in with tilt sensor to detect the uprightness of lamp post
- Built-in GPS positioning chip for auto-mapping of streetlight positioning
- Built-in light sensor for environment-based turning on/off of streetlights based on the brightness level
- Built-in RTC for onboard scheduled dimming
- Monitored parameters include voltage, power, current, energy consumption, power factor, temperature, and frequency, etc.
- Option for the built-in real-time clock can store device energy consumption data per day
- Service life- > 5 years
Features
- NEMA interface, compatible with standard ANSI C136.41

Note:
- State before shutdown: Working state of the product when no alarm is generated, if the product fails at 50% dimming, it will be restored to this state after the failure is removed.
- Restart: The product needs to be powered off and then powered on again.
- Execution actions: All execution within 4 seconds
