AEV250 Series DC
Contactor Specication
Application
AEV250 Series is used for charging (pile) station, battery power supply,
DC power control, circuit protection and other electric vehicle power switch
controls. Also it could be widely used in uninterruptible power supply and
other electronic control systems.
Features
HIGH CURRENT AND HIGH VOLTAGE
Contact chamber is led with inert gas to minimize arcing, up to 900VDC
load is available.
COMPACT STRUCTURE, LOW NOISE
Contact design yields reduced unit size, low noise while carrying or switching currents.
COIL ECONOMIZER
Built-in coil economizer – only 1.7W hold power @12VDC and it limits back EMF to 0V.
HIGH SAFETY
There is no arc leakage due to tight sealing.
HIGH RELIABLE CONTACT
Stable contact resistance no matter how harsh environment with sealed contacts.
NO SPECIAL REQUIREMENT FOR MOUNTING
Light weight actuator is less impacted by gravity with no special mounting orientation requirements.
VARIOUS APPLICATION
Application includes battery switch and standby equipment, DC power control, circuit protection, etc.

Application Note:
1. Be sure to use washer to prevent screws from loosening. Tighten the screw torque range is specied as below.
Exceeding the maximum torque can lead to product rupture.
• Contact torque (M8): 80 - 100 lb.in (8.8 - 11 N.m)
• Mounting torque: 15 - 30 lb.in (1.7 - 3.3 N.m)
2. Please refer to drawing for polarity sensitive type during connecting; No orientation for non-polar type.
3. Do not use dropped products.
4. Avoid to install the product in a strong magnetic eld (Close to the transformer or magnet), or near an object
with heat radiation.
5. Electrical life
Please use under load capability and life cycle so as not to cause a function failure. (Please also treat the
contactor as a product with specied life and replace it when necessary). It is possible to make parts burn
around the contactor once operating failure happens. So it is necessary to take layout into account to make sure
power shall be cut off within 1 second.
6. Lifetime of internal gas diffusion
The contactor is sealed and lled with gas, lifetime of gas diffusion is determined by temperature in contact
chamber (Ambient temperature + Temperature rising by contact energizing). Therefore environment
temperature should be from -40 to +85˚C.
7. Do not let particle and oil stain on the main terminal with which the load shall make a reliable contact. Or it will
cause a lot of heat.
