Cautions of Power Relay:
1.Suggestions of Plastic
Anti-dust Cover
We highly recommend cover :
(1)When the ambient humidity is ≥ 60% (for
example refrigerator or some country like Indian), the metal parts
of relay will be weakened in different degrees
due to long-term exposure to the
outdoors in terms of electrical conductivity and service
life. (2)When
the dust density is high in the environment, all kinds of
impurities carried in the dust (such as gravel), if gravel is
embedded between contacts.
Firstly, it will affect the normal opening and closing
of contacts;Secondly, part of the silicon oxide can be used as a
semiconductor to conduct electricity,
and then the relay's on and off will
fail if no anti-dust cover.
(3)When corrosive gases are serious in the
environment, it will accelerate the metal aging, greatly affecting
the service life of electrical relays.
* When none of the above situations
exists, the plastic anti-dust cover is not necessary due to extra
cost. 2.Suggestions
of Contacts (1)We
should pay attention to prevent contact movement, adhesion,
abnormal consumption, increase of contact resistance and other
fault phenomena while using.
(2)The material of power relay can be
AgCd010,AgSn08,AgSnOlnO etc.Wanjia star brand relay adopted AgSnO2
with high quality & stable performance.
(3)The mechanical service
life and electrical service life can be main factor too
* In a word, good device
need good relay to low the repairing rates and improve the
endurance./* January 22, 2024 19:08:37 */!function(){function
