What Are the Core Technical Features of the JL-215E التحكم في الإضاءة?
هذا مفتاح مستشعر الضوء الخارجي is built for higher voltage lighting applications. Its use is especially specific in 347 VAC systems that are common in large outdoor installations. It integrates automatic switching based on ambient light levels.
Electrical & Load Capabilities
It supports a 347 VAC-rated voltage with a wide working range up to approximately 382 VAC. The device handles typical lighting loads such as:
- 1000 W tungsten lamps
- 1800 VA ballast loads
Power draw is kept low, with a maximum of about 1 W, optimizing efficiency in continuous operation.
Light Switching Precision
- Switch-on level is approximately 10–30 Lux
- Switch-off level is around 30–60 لوكس
This ensures lights turn on reliably at dusk and off at dawn. The sensing accuracy parallels industry norms for electronic photocontrols.
Protection & Build Quality
Unlike some other models, JL-215E does not include zero-cross switching technology and lacks preset lux and time delay adjustments. This simplifies the circuit and reduces control options. However, it suits stable higher voltages.
Overall, JL-215E is a straightforward and robust choice for higher voltage applications where simplicity and reliable automation are priorities.
