ORDERING INFORMATION

200A type has been added. High Capacity of Max. 1,000 V DC Cut-off Possible EP RELAYS (AEP) (10A, 20A and 80A types) 10A PC board type 10A TM type 20A TM type 80A type 300A type 200A type New RoHS compliant

FEATURES

  1. High-voltage, high-current control capable 400V DC high-voltage switching and 1,000V DC cut-off has been achieved thanks to a sealed construction with mixed hydrogen gas and the magnetic arc motion through use of a permanent magnet. 2. Compact & Low Operating Sound By using a capsule contact mechanism that is enclosed with hydrogen gas, high- capacity cutoff is possible even with a tiny contact gap. There is little operating sound, which does not change even when large currents are cut off. 3. Arc space unnecessary The enclosure box can be made smaller thanks to an arc-space-free construction from which the arc will not get out. 4. Safety Since the contacts are enclosed in a sealed capsule structure, the arc will not get out, which ensures safety. 5. High contact reliability The contact part is hermetically sealed with H 2 mixed gas, hence the contact resistance remains stable regardless of the ambient conditions. 6. Mounting direction is not specified The weight of the movable parts is light, and also the restoring force is large, hence the relay is relatively unaffected by gravity. 7. Wide selection of models available. Types include PC board type (10A), TM type (10A and 20A), Lead wire type (200A) and Connector type (80A and 300A). 8. Standard compliance The 10A, 20A, 80A type is UL/C-UL standard certified. TYPICAL APPLICATIONS 1. Photovoltaic power generation systems 2. Cogeneration systems 3. Construction machinery 4.

Please read “GENERAL APPLICATION GUIDELINES” for regular cautionary items. 2. When installing the relay, always use washers to prevent the screws from loosening. Tighten each screw within the rated range given below. Exceeding the maximum torque may result in breakage. Mounting is possible in either direction.

We recommend installing a surge protector varistor for the 10A, 20A, 80A and 200A types. Please note that when using a diode, the switching speed may decrease and cause a reduction in cut-off performance. For the 300A type, separate surge countermeasures are not required, because it contains a built-in surge absorbing element. <Recommend varistor> Amount of proof energy: Min. 1 J Varistor voltage: 1.5 to 3.0 times of nominal voltage 4. Do not use a relay if it has been dropped. 5. Avoid mounting the relay in strong magnetic fields (near a transformer or magnet) or close to an object that radiates heat. 6. Electrical life This relay is a DC high-voltage 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.

Permeation life of internal gas This relay uses a hermetically encased contact (capsule contact) with gas inside. The gas has a permeation life that is affected by the temperature inside the capsule contact (ambient temperature + temperature rise due to flow of electrical current). Therefore, please do not exceed the operation ambient and storage ambient temperatures given in the specifications. 8. Do not disassemble the relay. Please note that disassembling the relay will invalidate the warranty. 9. If the power is turned off and then immediately on after applying the rated voltage (current) continuously to the relay’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 these circumstances, 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. 10. Pure DC current should be applied to the coil. If it includes ripple, the ripple factor should be less than 5%. However, check the actual circuit since the characteristics may be slightly different. The power supply waveform supplied to the coil should be rectangular. Also, the 300A type has a built-in dedicated drive circuit. It may not operate normally unless the rise time is 10 ms or less. 11. Don’t exceed maximum coil voltage. Exceeding maximum allowable coil voltage on continuous basis will damage the relay and could case failure. 12. If you will be using with a load voltage that exceeds 400 V DC, please be sure to verify operation on the actual device, referring to the switching life curves (reference data). You must absolutely avoid continual use in which the load current exceeds the rated value. This will cause abnormal heating. 13. The rated control capacity and life are given as general guides. It is important to conduct sufficient tests on the actual device, because contact properties and working life will differ considerably depending on the type of load and conditions. 14. 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 the inductive load. If this is not done, the electrical life will decrease and cut-off failure may occur. In order to prevent contact welding when using a capacitive load (C load) such as a capacitor load, please make the inrush current setting more than two times that of the nominal current. Please contact us for more information. 15. 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 off unusual heat. Also, please use the following materials for connected harnesses and bus bars. 10A TM type: #187, 0.5 mm board thickness 20A TM type: #250, 0.8 mm board thickness tab terminal (JIS C289-1999 compliant, flat type connection terminal) Harness nominal cross-sectional area Load input terminal side; 10A TM type: min. 2.0 mm 20A TM type: min. 3.0 mm2 Coil input terminal side; 10A and 20A TM types: min. 0.3 mm 80A type: min. 15 mm2 200A type: min. 60 mm2 300A type: min. 100 mm2 16. Use 40 to 70N or 50 to 80N of force as a guide to fasten the terminal connected to the 10A TM and 20A TM types. Please use caution when inserting or removing the terminal as the relay tab terminal may cause injuly. Also, unstable conductivity and abnormal terminal heating may occur; therefore, please check that there is no deformation of or foreign objects on the faston terminals (blade receptacle) you will be connecting. Use JIS C2809 (or IEC60760) certified products. 17. 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 18. Make sure the power is turned off when wiring. 19. Incorrect wiring may cause unexpected malfunction and failure. 20. 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. 21. 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). 22. 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 98N. Avoid excessive tension as this is a cause of broken wires and damage. Also, insert the female connector deeply and make sure the connection is secure. 23. Condensation will occur during sudden temperature changes in hot and humid environments. Caution is required, because condensation will cause a decrease in the insulation resistance between the terminals.
