使用场景 APPLICATIONS

1 Railway on-board equipment: centralized lighting systems, air conditioning units, and related on-board electronic devices

2 Industrial control systems requiring wide input voltage and high isolation

3 Harsh environment applications where stable performance across extreme temperatures (-40°C to +105°C) is needed

4 Equipment needing reliable power conversion with multiple protection mechanisms

注意事项 PRECAUTIONS

1 When not using the remote sense function, connect the +sense pin to +Vout and -sense pin to -Vout using the shortest possible traces to minimize voltage drop and interference

2 When using the remote sense function, connect sense pins to the load with short twisted pair or shielded wires, ensuring the voltage drop between the converter output and load is less than 0.3V

3 Follow the recommended EMC circuits (as provided in the datasheet) to meet EN50155 and other EMC standards

4 Use the optional -K heat sink for improved thermal performance in high-temperature operating conditions

5 Adhere to the maximum mounting hole screw torque of 0.4 Nm during installation

6 Do not exceed the absolute maximum ratings specified in the datasheet to avoid damage to the converter

7 Store the converter in an environment with temperature ranging from -55°C to +125°C and non-condensing humidity up to 95%

8 Refer to the latest version of the Aimtec datasheet (available at www.aimtec.com) for any updated specifications or guidelines

9 This product is not designed for use in life support systems, nuclear facilities, or other hazardous environments unless explicitly approved by Aimtec
