Question:

What is the meaning of the electrical life unit Ops / min in the relay?

OMRON relay G9EA-1 PDF data there Electrical endurance (See note 6.): 400 VDC, 30 A, 30,000 Ops / min. 400 VDC, 60 A, 3,000 Ops / min. 120 VDC, 100 A, 3,000 Ops / min. And now do not understand what this means! Look under the detailed instructions There is trouble to recommend a relay can be placed on the PCB board Requires electric shock voltage 300VDC because I want to give a group of charge to 300V capacitor discharge instantaneous current is about 1200A away Trouble to recommend a relay can be placed on the PCB board Requires shock voltage 300VDC because I want to give a group of charge to 300V capacitor discharge current is about 1200A

Answer:

Ops / min. Ops is the abbreviation for Operations, which means the maximum number of switches (or actions) per minute, but some kind of relay will have its life, that is, how many times it can switch, for example, thousands of times. 400 VDC is the maximum voltage of the coil. 30A is the maximum switching current number The other you have to choose according to the equipment sample manual.

Is not you wrong, the relay can not do so the use of high frequency, the relay life has 30W times the argument, that life is 30W times, 400 VDC, 30 A, 30,000 Ops / min. 400 VDC, 60 A, 3,000 Ops / min. 120 VDC, 100 A, 3,000 Ops / min It should be said that the relay in the case of 400VDC.30A can do 3W times 400VDC60A can do 3 thousand 120VDC100A can do 3 thousand times, but I can tell you that this is impossible to do, or is the product price wrong , If it is 400VAC30A is no problem, I was doing relay life test,

400 VDC, 30 A, 30,000 Ops / min. 400 VDC, 60 A, 3,000 Ops / min. 120 VDC, 100 A, 3,000 Ops / min. Means the maximum number of switches (or actions) per minute at 300 VDC, 30 A load. The other two meanings are not the maximum voltage figures for the coils.
