▍Precautions during the use of Heat Sink

Heat Sink
  • Using standard heat sink is mandatory for this product.
  • Even if a standard heat sink is used, HSR may be damaged if the surrounding temperature rises or ventilation is poor, so please be careful. (Ambient temperature: 40° or higher)
  • Usually, the HSR is damaged when the max temperature of the element exceeds 125°, and when the heat sink temperature is above 85°, the temperature of the element becomes close to 125°, so be sure to measure the heat sink temperature during operation.
  • When you connect HSR onto the heat sink, heat-transmitting grease is needed for smooth heat transmission.
  • To prevent separation by vibration, tighten up with bolts.
  • Do not use any insulating materials such as wood, plastic or rubber. The standard heat sink must be greased on the bottom side as shown and connected. ※ The heatproof silicon grease must be applied thoroughly on the heat sink as well as the bottom of HSR. The case side of heat sink needs to be installed on up and down directions.
