The intelligent outdoor light controller for NEMA socket

The OLC NEMA is an outdoor lighting controller. You can easily install it on a luminaire head equipped with a NEMA socket. It is available with a combined 1-10V and DALI interface, for example, to dim the lighting or to detect malfunctions.

Its sleek and flat design case will match the aesthetics of your street furniture. It is available in light gray or dark gray.

In short


Streetlight control

The controller communicates with the luminaire ballast via a 1-10V or DALI interface (to be configured during commissioning). While the 1-10V only allows light intensity reduction, the DALI interface offers additional features such as failure detection by the ballast.


Streetlight switching

You can switch on the controller either by using a traditional centralized remote control or thanks to a constant power supply. In the first case, the controller switches on simultaneously as the luminaire; it then starts the application of the configured dimming profiles. The astronomical clock built into the controller plays a central role in the second case. This clock computes the sunset, and sunrise times, according to the streetlight coordinates and the date. On this astronomical basis, you also can incorporate sunset and sunrise offsets depending on the observations made in the field.

Light intensity reduction profiles can be configured easily on the remote management software and are synchronized to the controller via the wireless network.

Energy measurements

The integrated energy meter enables measurements of energy consumption and savings. In addition, instantaneous measurements can be retrieved on request: frequency, voltage, current, power, and power factor. You can store the measurements in remote management software for analysis.

Fault detection

The luminaire controller continuously monitors electrical parameters, luminaire operating status, configuration, or communication faults. These faults are detected either directly by the luminaire controller or by the luminaire drivers (be careful, the use of DALI control mode is required).

Electrical faults
Lamp faults
Configuration or communication faults

Power control

The controller is equipped with a power relay and can thus cut off power to the lamp when needed while maintaining the communication network functional for other applications.

Streetlight controller for NEMA socket

The NovaLight OLC NEMA is an outdoor lighting controller compatible with the standardized NEMA socket. It allows, through different strategies, to dim public lighting when road occupancy decreases and thus achieve significant energy savings. These savings can be measured using the integrated energy meter. In addition, lighting faults are automatically detected and sent to centralized remote management software via a wireless network.

Product features

Dimensions (mm) : 54(H)*92(l)*137(P)
Weight : 250gr

The controller is made of anti-UV PC / ASA plastic and grade V0. Its housing has a concentric pressure locking mechanism that secures the controller to the connector with the silicone seal. The mechanism is activated by tightening two Torx T8 screws on the side of the product.

Environmental parameters Min Type Max Unit
Operating temperature -30 +70 °C
Operating humidity 10 90 %RH
Degree of protection IP66
Impact protection IK09
Integrated DALI power supply : 50mA

The controller connects to the current via the NEMA connector, which derives the 230VAC power supply. NEMA connectors are available in different variants:

  • NEMA 3-poles The NovaLight OLC NEMA is compatible with 3-pole connectors as long as the power relay uses an on-off control mode. The 3-poles are the input phase (Li), neutral (N), and output phase (Lo).
  • NEMA 5-poles With the 5-pole connector, it is also possible to dim the streetlights if they offer a DALI or 1-10V control interface. The product can be configured to operate with the correct interface.
  • NEMA 7-poles The NEMA 7-pole connector adds two additional control signals that are not exploited by the NovaLight OLC NEMA controller.

The controller is connected to centralized software via a low-data-rate, low-power, mesh-topology wireless network. A mesh topology implies that the communication network initially generated by a NovaLight Gateway access point/router/gateway can be extended by all the connected controllers (signals relayed by the controllers). Controllers can also exchange messages directly with each other. This mechanism is used in particular to create light paths with dynamic lighting.

This product is available in different variations. Two colors are available: steel gray (RAL7040) or anthracite gray (RAL7015). The control mode must also be chosen. Depending on the possibilities of the streetlight ballasts, either 1-10V or DALI (to be preferred if possible).

Frequently asked questions
How to install the NovaLight OLC NEMA?

The NovaLight OLC NEMA controller is easy to install. First, you must fit the silicone seal on the connector and then insert the controller. The index N indicates the final position of the controller. To plug it in, insert it at an angle of 50-60 ° to the left, then turn it clockwise until it stops. Optionally, you can tighten the locking mechanism with a T8 Torx screwdriver evenly on each side.

How to commission the NovaLight OLC NEMA?

You must register the NovaLight OLC NEMA in the remote management software to be operational. To do this, we recommend that you use the NovaLight mobile application, which allows you to select/create a light point, scan the product barcode required for its registration, and enter the product details. Once you have referenced the controller in the software on its corresponding light point, as soon as you power on the lighting infrastructure and the NovaLight Gateway router, the controller can connect to the remote management software to receive its configuration.

How to select the DALI or 1-10V interface?

During commissioning, whether with the mobile application or the web platform, it is possible to select the control mode of the controller, either Relay (on / off), 1-10V, DALI, or none. You set up this configuration in the streetlight controller, not the light point. Once configured, the controller will receive its parameters when connected to the remote management platform.

Can the NovaLight OLC NEMA control non-LED streetlights?

Yes, but only with control by the electrical power in on/off mode. It is possible to measure the energy consumption of the light point to manage its switching on / off. However, dimming of non-LED streetlights is not possible. It is also necessary to verify that the streetlight driver power matches the electrical power limits of the controller.

How do I know if the product is working?

The ideal approach is to verify proper operation through the remote management platform, either through the web interface or mobile application. If you switch on the luminaire and the lighting network, you can make instant manual checks. Changing the light intensity and checking the energy data makes it possible to certify that the dims are working correctly. On-site and during the day, the controller will generally switch on the luminaire. However, this depends on the setback schedule configured. For example, the program can activate the astronomical clock function, which will switch off the lights during the day.

Can this controller manage multiple streetlights?

The controller can perform diagnostics for up to 12 different streetlights on the DALI bus. The controller will only transmit general commands that will impact all the lights uniformly in terms of intensity control.

Can the NEMA NovaLight OLC apply volumetric or dynamic dimming?

Yes. You can integrate the NEMA NovaLight OLC into a volumetric dimming strategy. This controller does not host integrated detectors for dynamic dimming based on motion detection. However, it can still react either to a D4i sensor connected to the streetlight or detections from other controllers.
