数据程序电路通过对RY1 触点的ON/OFF时间进行控制以改变微波炉从“低”功率到“高”功率的输出功率。

继电器RY1 ON/OFF的一次完整循环时间为22秒钟。

下表中给出的是设定的火力和微波输出之间的关系。

修理实例Repair Manual现象描述： 红灯闪一下的故障，故障部位有两个：一是P 板各路电源有的没有输出造成A 板总线没有电源。

二是A 板故障，通常是因为各IC 之间通讯不通造成的。

原因分析： 测量P 板输出排插，发现有待机5V 、待机15V 输出，但没有15VcVDA 、VSUS 输出。

P 板电路原理分析：该机的P 板电路比效简单，有三个开关电源电路：1、待机电源电路由IC201、T200组成。

输出待机5V 、15V 。

2、PFC 电路由IC100、T100组成。

产生390V 电源。

3、VSUS 、VDA 、15V 电源由同一个开关电源产生：IC301、T301、T300。

上述三个开关电源工作的前后时间顺序是有严格的规定的：通电后待机电源先工作，不论面板上的电源开关是否闭合，只要接通220V 市电，待机电源就工作。

产生并输出待机5V 、15V 电压。

待机电源开始工作后，在待机电源变压器T200：1—2绕组间产生的脉冲电压经D209整流C210滤波，产生24V 电源电压，经开关管Q100加到两个三端稳压器输入端：经IC101输出20V 电源，经IC102输出15V 电源。

其中20V 电源是给IC301供电的，用于产生VSUS 、VDA 、15V 电源，IC102输出的15V 电源给IC100供电，用于产生PFC 电源。

由此看出：只有待机电源先工作，PFC 电源振荡IC 才能得电工作。

产生PFC 电源电压后，将此PFC 电源加给Q304、Q305、Q306、Q307。

VSUS 、VDA 、15V 电源才能随后工作。

这是PDP 电视机P 板工作的重要一环。

待机电源电路：IC201是单片开关电源专用IC ，只有三个引脚，外围电路最为简单。

其中2脚是IC 内大功率MOS 管的S 极，接地。

3脚是D 极，接开关电源变压器T200初级绕组。

1脚是稳压控制输入端。

电视机电源插头输入220V 市电后，经D200整流，C201滤波，产生300V 电压，加到T200初级绕组，并经T200：7、D204加到IC201的D 极，IC201开始振荡， T200初级流过脉冲电流，在次级产生脉冲电压，其中13—10绕组产生的脉冲电压经整流产生5V 待机电源。

ORDERING INFORMATION10A PC board type10A TM type60A Screw terminal type80A Connector type300A Connector typeFEATURES1. High-voltage, high-current controlcapable400V DC high-voltage switching cutoffhas been achieved thanks to a sealedconstruction with mixed hydrogen gasand the magnetic arc motion through useof a permanent magnet.2. Compact & Low Operating SoundBy using a capsule contact mechanismthat is enclosed with hydrogen gas, high-capacity cutoff is possible even with a tinycontact gap. There is little operatingsound, which does not change evenwhen large currents are cut off.3. Arc space unnecessaryThe enclosure box can be made smallerthanks to an arc-space-free constructionfrom which the arc will not get out.4. SafetySince the contacts are enclosed in asealed capsule structure, the arc will notget out, which ensures safety.5. High contact reliabilityThe contact part is hermetically sealedwith H2 mixed gas, hence the contactresistance remains stable regardless ofthe ambient conditions.6. Mounting direction is not specifiedThe weight of the movable parts is light,and also the restoring force is large,hence the relay is relatively unaffected bygravity.7. Wide selection of models available.T ypes include PC board type, TM type(10A), screw terminal type (60A), andconnector type (80A and 300A).8.

When installing the relay, always use washers to prevent the screws from loosening.Tighten each screw within the rated range given below. Exceeding themaximum torque may result in breakage. Mounting is possible in either direction.•M5 screw (60A, 80A and 300A main unit mounting section): 3 to 4N·m •M3.5 screw (60A input terminal): 0.84 to 1.2 N·m•M4 screw (10A PC board type main unit mounting section): 0.98 to 1.2N·m (10A TM type main unit mounting section): 1.8 to 2.7N·mRecommended securing torque on load side terminals•60A/M5 screw: 2.5 to 3.6 N·m •80A/M5 bolt: 3.5 to 6.5 N·m •300A/M8 bolt: 10 to 12 N·m2. The contacts of the relay arepolarized. Please follow instructions in the connection schematic when connecting the contacts.We recommend installing a surgeprotector varistor (ZNR) for the 10A , 60A and 80A types. Avoid using a diode as this may result in decreased cut-off capability.3. Do not use a relay if it has been dropped.4. Avoid mounting the relay in strong magnetic fields (near a transformer or magnet) or close to an object that radiates heat.5. Electrical lifeThis relay is a high-voltage direct-current switch. In its final breakdown mode, it may lose the ability to provide the proper cut-off. Therefore, do not exceed the indicated switching capacity and life. (Please treat the relay as a product with limited life and replace it when necessary.)In the event that the relay loses cut-off ability, there is a possibility that burning may spread to surrounding parts, so configure the layout so that the power is turned off within one second and from the point of view of safety, consider installing a failsafe circuit in the device.Also, in order to avoid increased contact resistance, do not operate when there is no switching load.6. Permeation life of internal gasThis relay uses a hermetically encased contact (capsule contact) with gas inside. The gas has a permeation life that is affected by the temperature inside thecapsule contact (ambient temperature + temperature rise due to flow of electrical current). For this reason, make sure the ambient operating temperature isbetween –40 and 80°C –40 and +176°F , and the ambient storage temperature is between –40 and 85°C –40 and +185°F .7. Do not disassemble the relay.Please note that disassembling the relay will invalidate the warranty.8. If the power is turned off and then immediately on after applying the rated voltage (current) continuously to therelay’s coil and contact, the resistance of the coil will increase due to a rise in the coil temperature. This causes the pick-up voltage to rise, and possibly exceed the rated pick-up voltage. In thesecircumstances, take measures such as reducing the load current, limiting the duration of current flow, and applying a coil voltage higher than the rated operating voltage.9. Coil operating powerPure DC current should be applied to the coil. The wave form should berectangular. If it includes ripple, the ripple factor should be less than 5%. However, check the actual circuit since thecharacteristics may be slightly different.The power supply waveform supplied to the coil should be rectangular.10. Don’t exceed maximum coil voltage. Exceeding maximumallowable coil voltage on continuous basis will damage the relay and could case failure.11. Ensure that the rated contacts voltage and current values are not exceeded.12. The rated control capacity and life are given as general guides.The contact life is heavily influenced by the type of load and other related conditions, and these factors must be kept in consideration when using the relay.13. Main contact ratings in the ratings apply to when there is a resistive load. If you are using an inductive load (L load) such that L/R > 1 ms, add surge protection in parallel with theinductive load. If this is not done, the electrical life will decrease and cut-off failure may occur.14. Be careful that foreign matter and oils and fats kind don’t stick to the main terminal parts because it is likely to cause terminal parts to give offunusual heat. Also, please use the following materials for connected harnesses and bus bars.•10A TM type: Faston terminal for #187 tab terminal, 0.5 mm board thickness (JIS C2809-1992 compliant, flat type connection terminal)Harness nominal cross-sectional area Load input terminal: min. 2.0 mm 2Coil input terminal: min. 0.3 mm 2•60A and 80A types: Min. 14mm 2 nominal cross sectional area•300A type: Min. 100mm 2 nominal cross sectional area15. Use 40N to 70N of force as a guide to fasten the terminal connected to the 10A TM type. Please use caution when inserting or removing the terminal as the relay tab terminal may cause injuly.16. Place the PC board mount type (10A PC board type) securely by hand soldering after attaching it using M4 screw. Don’t submerge assembled board in cleaning solvent or water. Also, be careful not let flux overflow up from the PC board or adhere to the base of the relay.Recommended hand soldering conditions• Soldering iron: 30 to 60 W • Tip temperature: 400°C 752°F• Solder time: within approx. 5 seconds 17. Make sure the power is turned off when wiring.18. Incorrect wiring may causeunexpected malfunction and failure.19. Regarding AC cutoff, although there is no contact polarity, generally it is thought that the electrical life will shorten due to cutoff in the reverse direction, compared to DC cutoff. Confirm electrical life using actual load. In the case of DC cut-off, please note the contact polarity.20. Lead-free solder (tin, silver and copper) is used as pre-solder for the terminals of the PC board mount type (10A PC board type).21. The warranted tensile strength of the female connector lead wire used for connection that comes with the 80A and 300A connector type when attaching it to the relay body is 100N. Avoid excessive tension as this is a cause of broken wires and damage. Also, insert the female connectordeeply and make sure the connection is secure.。
