Introduction

Technical Parameters

Certificate

Excellent compatibility for different national or international standard

Features

1. LED

• 3~5-year service life, reduce the cost for maintenance and replacement.
• Comparatively, LED could save 80% energy compared to incandescent light, save 50% compared to fluorescent lamp, and save 70% compared to HPSL (high pressure sodium lamp).
• Semiconductor material, ALL parts can be recycled.
• Visual-friendly.
• Closer to natural daylight.
• As a solid light source, LED has outstanding performance in shake-resistance, not easy damaged.
• Can be connected to an external battery, working voltage is 85~265V AC, the voltage fluctuation would not affect its performance and service life.
• -40 ℃~+60 ℃ working temperature
• Power could be adjusted, provides possibilities for future expansion on intellectualized functions.

Types for different occasions:

1. Street Light
2. Tunnel Light
3. Flood Light

Types driven by different energy source (can be mixed type):

1. Electricity driven
2. Wind power driven
3. Solar panel driven

2. Concentrator Unit:

• Data collection: data acquisition of watt-hour meter, state quantity collection (reservation), data acquisition of street lighting controller.
• Data storage and management: real-time and current data, historical data, watt-hour meters, street lighting controllers and other equipment operating status monitoring.
• Parameter setting and tracing: management policy settings and tracing, terminal parameters, street lighting controllers, summary table parameter, calling for clock and timing.
• Controlling: local control (according to management policy setting/local command), remote control (command issued by master station)
• Event recording: important event record, general event record.
• Data transmission: communication with master station, street lighting controller, watt-hour meter, and user data interface.
• Local function: displays relevant information, respond to human-computer interactive input, user data interface
• Smart maintenance unit: Self-examining and self-recovery, remote terminal initialization, software remote upgrade.

3. Single-capped Lamp Controller:

• Controlling Function: through the voltage output of the power line carrier wave adjustment controller 0~10V, and the PWM duty cycle output, the dimming range is 0%~100%, the electrodeless dimming is less than 2%, and the adjustment accuracy is less than 2%.
• Measuring Function: built-in electric energy measurement function, the measurement accuracy can reach 2%
• Monitoring Function: each lamp can be monitored remotely, and the voltage, current, power, power factor and working status of the street lighting can be monitored at any time.
• Alarming Function: the running status of the controller can be reported in real time through the power line carrier, including overvoltage, overcurrent, overload, abnormal lamps and lanterns, etc. At the same time with anti-theft of electricity, cable anti-theft and other functions.
• Parameter Setting: parameter setting and maintenance can be done remotely.
• Protection Function: equipment will automatically alarm and shut down when the temperature is too high, or the power is too high, or the voltage is too high or too low. When the temperature is too low and the output circuit is open, it will alarm until the fault is removed.

Situation

Intercity highway, urban road, rural road,tunnel, culvert, road intersection, large square, open space required strong lighting.

Introduction

As the first company in Hunan Province to be listed on SSE STAR Market, Willfar is the pioneer manufacturer in China that can simultaneously provide related industries with all kinds of advanced electricity, water, gas and heat metering products and meters for power distribution, power quality monitoring equipment, a full range of energy data concentrators, relay protection equipment, switchgear products and equipment related to metering automation system and all kinds of application systems as well as services which cover the demand of the whole process of energy production, distribution, transmission and consumption.

Willfar Information Technology Co., Ltd always focuses on customers and takes full control of products’ delivery and deployment, including the process of designing, testing and experimenting as well as the manufacturing process of raw material. We attach great importance to production control plan, potential failure mode and product reliability design which require us to implement the production approval procedure and control the production process strictly so as to ensure the products’ quality.

On November 4, 2013, President Xi Jinping, also general secretary of the Communist Party of China (CPC) Central Committee, visited Wasion in Changsha. He visited the product showroom and production workshops, where he talked with workers and labor models. Xi spoke highly of Wasion's achievements in product development and market expansion and encouraged the company to step up innovation in technology, management, product, marketing and branding.

So far, Willfar has 396 valid patents, of which 26 are invention patents, 240 pieces for utility model, 130 pieces for design and 442 software copyrights; it has also received 10 technical awards of provincial or ministerial level or above. Willfar has participated in the setting of 15 national industry standards, 10 of which have been published.

Willfar Information Technology Co., Ltd takes "smart manufacturing capability" as one of its core competing powers by realizing the whole process data tracing and full-lifecycle management of product design, processing, procurement, production, logistics and service via SCM, CRM and APS on the basis of ERP, PDM, PLM and MES.
