电子镇流器自身功耗低，有更佳的照明效果，消除了闪频现象，发光更稳定，而且可以调光。

文章采用AVR单片机作为控制芯片，通过电子镇流器进行调光和相关功能的控制，最大限度地发挥智能型镇流器的特点。

实际应用表明，文中的方法有效。

0 引言电子镇流器是新型节能产品，不仅能带动一些照明灯具，还可以和一些紫外灯结合在一起，对于空气净化和水源净化都有着非常大的作用。

当前，全世界都在大力提倡环境保护，电子镇流器间接地为环保提供了原动力。

AVR单片机是一款性价比较高的单片机，用这种单片机来对电子镇流器进行调光和时间采样非常合适，首先是AVR单片机本身较稳定，抗干扰能力比较强，其次是其本身的Harvard结构使得运行速度比较快，数据回读时间较快，可以实现实时在线控制。

1 AVR单片机介绍1.1 AVR单片机的特点与以往的8位单片机相比，AVR单片机采用Harvard结构，也就是程序总线和数据总线分开，并采用两级流水线，具备1MIPS/MHz的高速运行处理能力。

片内集成多种频率的RC振荡器、上电自动复位、看门狗、启动延时等功能模块，外围电路简单，系统更加稳定可靠。

大部分AVR片上资源丰富：带E2PROM、PWM、RTC、SPI、UART、TWI、ISP、AD、Analog Comparator、WDT等单元模块。

1.2 AVR单片机的PWM功能AVR单片机的定时器功能强大，以Atmega48为例，它有两个8位定时器和一个16位定时器，都具有硬件PWM功能。

All applicable legal or institutional installation regulations must be complied with during installation.The switch for changing the direction of motion and so the closing point may be adjusted only by authorised specialists. The direction of motion is critical, particularly in connection with frost protection circuits.The device may only be opened at the manufacturer's site. It does not contain any parts that can be replaced or repaired by the user.The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed.Product featuresOperating modeConventional operation:The actuator is connected with a standard control signal of 0...10 V and drives to the position defined by the control signal. The measuring voltage U serves for the electrical display of the actuator position 0.5...100% and as control signal for other actuators.Operation on Bus:The actuator receives its digital control signal from the higher level controller via the MP-Bus and drives to the position defined. Connection U serves as communication interface and does not supply an analogue measuring voltage.Converter for sensors Connection option for a sensor (passive or active sensor or switching contact). The MPactuator serves as an analogue/digital converter for the transmission of the sensor signal viaMP-Bus to the higher level system.Parametrisable actuators The factory settings cover the most common applications. Single parameters can be modifiedwith the Belimo service tools MFT-P or ZTH EU.Mounting on third-party valves The RetroFIT+ actuators for installation on a wide range of valves from various manufacturersare comprised of an actuator, bracket, universal valve neck adapter and universal valve stemadapter. Adapt the valve neck and valve stem to begin with, then attach the RetroFIT+ bracketto the valve neck adapter. Now fit the RetroFIT+ actuator into the bracket and connect it to thevalve. Whilst taking the position of the valve closing point into account, secure the actuator tothe bracket and then conduct the commissioning process. The valve neck adapter/actuatorcan be rotated by 360° on the valve neck, provided the size of the installed valve permits.Mounting on Belimo valves Use standard actuators from Belimo for mounting on Belimo globe valves. The installation ofRetroFIT+ actuators on Belimo globe valves is technically possible.Manual override Manual override with push-button possible (the gear train is disengaged for as long as thebutton is pressed or remains locked).The stroke can be adjusted by using a hexagon socket screw key (4 mm), which is insertedinto the top of the actuator. The stroke shaft extends when the key is rotated clockwise.High functional reliability The actuator is overload protected, requires no limit switches and automatically stops whenthe end stop is reached.Home position Factory setting: Actuator stem is retracted.The first time the supply voltage is switched on, i.e. at the time of commissioning, the actuatorcarries out an adaptation, which is when the operating range and position feedback adjustthemselves to the mechanical setting range.The actuator then moves into the position defined by the control signal.Adaptation and synchronisation An adaptation can be triggered manually by pressing the "Adaptation" button or with the PC-Tool. Both mechanical end stops are detected during the adaptation (entire setting range).Automatic synchronisation after pressing the manual override button is configured. Thesynchronisation is in the home position (0%).The actuator then moves into the position defined by the control signal.A range of settings can be adapted using the PC-Tool (see MFT-P documentation)Setting direction of motion When actuated, the stroke direction switch changes the running direction in normaloperation.AccessoriesGateways Description TypeGateway MP to BACnet MS/TP UK24BACGateway MP to Modbus RTU UK24MOD Electrical accessories Description TypeAuxiliary switch 2x SPDT add-on S2A-HMP-Bus power supply for MP actuators ZN230-24MP Mechanical accessories Description TypeSpacer ring for LDM, stroke 20 mm ZNV-203Spacer ring for Sauter, stroke 20 mm ZNV-204Adapter kit Danfoss ZNV-205Tools Description TypeZTH EUService tool, with ZIP-USB function, for parametrisable andcommunicative Belimo actuators, VAV controller and HVAC performancedevicesSVC24A-MP-REDescriptionType Belimo PC-Tool, Software for adjustments and diagnostics MFT-P Adapter for Service-Tool ZTHMFT-C Connecting cable 5 m, A: RJ11 6/4 ZTH EU, B: 6-pin for connection to service socketZK1-GEN Connecting cable 5 m, A: RJ11 6/4 ZTH EU, B: free wire end for connection to MP/PP terminalZK2-GENAccessoriesElectrical installationSupply from isolating transformer.Parallel connection of other actuators possible.

The responsibility for the applicability and use in a particular customer design is always solely within the authority of the customer. Due to this fact it is up to the customer to evaluate, where appropriate to investigate and decide whether the device with the specific product characteristics described in the product specification is valid and suitable for the respective customer application or not.2. Customer Responsibility related to Specific, in particular Safety-Relevant ApplicationsIt has to be clearly pointed out that the possibility of a malfunction of electronic components or failure before the end of the usual lifetime cannot be completely eliminated in the current state of the art, even if the products are operated within the range of the specifications.In certain customer applications requiring a very high level of safety and especially in customer applications in which the malfunction or failure of an electronic component could endanger human life or health it must be ensured by most advanced technological aid of suitable design of the customer application that no injury or damage is caused to third parties in the event of malfunction or failure of an electronic component.

Best Care and AttentionAny product-specific notes, cautions and warnings must be strictly observed. Any disregard will result in the loss of warranty.4. Customer Support for Product SpecificationsSome products within the product range may contain substances which are subject to restrictions in certain jurisdictions in order to serve specific technical requirements. Necessary information is available on request. In this case the field sales engineer or the internal sales person in charge should be contacted who will be happy to support in this matter.5. Product R&DDue to constant product improvement product specifications may change from time to time. As a standard reporting procedure of the Product Change Notification (PCN) according to the JEDEC-Standard inform about minor and major changes. In case of further queries regarding the PCN, the field sales engineer or the internal sales person in charge should be contacted. The basic responsibility of the customer as per Section 1 and 2 remains unaffected.6. Product Life CycleDue to technical progress and economical evaluation we also reserve the right to discontinue production and delivery of products. As a standard reporting procedure of the Product Termination Notification (PTN) according to the JEDEC-Standard we will inform at an early stage about inevitable product discontinuance. According to this we cannot guarantee that all products within our product range will always be available.
