AEV250 Series DC Contactor Specification 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 filed 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. COMPLY WITH EU ROHS DIRECTIVE (2011/65/EU) Nomenclauture Example AEV250 -- M AN Series code: "AEV250" = AEV250 Series Coil Voltage Code:: "M" = 12 - 24 VDC Options (applied in this order): Blank = Std.

Tighten the screw torque range is specified 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 field (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 specified 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 filled 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 +85C. 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. 1741 Industrial Drive, No. 14 * Sterling, IL 61081 Tel: 815-632-3150 * Fax: 815-632-3449 www.altranmagnetics.com * sales@altranmagnetics.com 5
