2.5KV AC Power Relay For EV Charger Station Sealed 30 Amp Relay
Relay Characteristics of Relays
The input signal x of the relay increases continuously from zero to
the action value xx when the armature starts to pull in, and the
output signal of the relay immediately jumps from y=0 to y=ym, that
is, the normally open contact changes from off to on. Once the
contact is closed, the input quantity x continues to increase, and
the output signal y will no longer change. When the input quantity
x drops to xf from a value greater than xx, the relay starts to
release and the normally open contact is disconnected. We call this
characteristic of the relay characteristic, also called the
input-output characteristic of the relay.
AC Power Relay Description:
New energy products, like electric vehicles, must be a trend in the
next few days. So more and more fast-charging stations are made and
satisfy the need for electric cars power-charging.NB90 series AC
relay is specially applied to the charging point. It is a high
switching capacity for contacts, is a dust-proof or sealed type
option, and is environmentally friendly.
AC Power Relay Features:
1. 4000VAC or 2500VAC is available for dielectric to withstand
voltage between contact and coil
2. Class F for coil insulation grade
3. SPDT & SPST
4. Rated current max 40A
5. 900mW
6. TUV/CQC/UL certification
The relay has the following functions:
(1) Expand the control range: For example, when the multi-contact
relay control signal reaches a certain value, it can switch, break,
and connect multiple circuits at the same time according to the
different forms of the contact group.
(2) Amplification: For example, sensitive relays, intermediate
relays, etc., can control large power circuits with a very small
control amount.
(3) Integrated signal: For example, when multiple control signals
are input into the multi-winding relay in the prescribed form, the
predetermined control effect is achieved after comparison and
synthesis.
(4) Automatic, remote control, monitoring: For example, the relay
on the automatic device and other electrical appliances can form a
program control circuit to realize automatic operation.
AC Power Relay Note:
1. Using under a clean environment(excluding H2S, SO2, NO2, dust
contaminants), dust-proof type is recommended using under a
polluted environment(containing H2S, SO2, NO2, dust contaminants),
sealed type is recommended, and please contact us during practical
application；
2. When assembly on PCB, it needs to be completely washed, please
inform us before ordering, so as to provide the proper types;
3. If the dielectric strength between the coil & contacts has to be
over 2500VAC, please inform us before ordering, so as to provide
the proper types.
4. Avoid using it under strong magnetic or shock extremes
conditions, or the technical rating will be changed.
