Switching Power Supply (DIN Rail-Mounting, Low-Profile, 24 VDC Output)

Switching Power Supply (DIN Rail-Mounting, Low-Profile, 24 VDC Output)
  • Volume Discount

DIN Rail / Low-Profile Ideal for Shallow Boards

  • c-UL
  • CE-Compliant
  • TUV
  • DIN Rail

● Low profile model with 56 mm depth (approx. 44% reduction compared to ESP20 series)
● Installed on 35 mm DIN rail
● European screw model terminal for easy connection
● Resin case (15 – 100 W)


∙ Due to high voltage and high temperature areas within, do not touch the product during use or immediately after powering off. Risk of electric shock and burn injury.
∙ If the voltage from the output terminal exterior exceeds the output voltage range, there is a risk of power malfunction.
∙ The power supply is not fitted with a ground terminal. To prevent noise from entering via the power line, it is recommended to connect an external noise filter.
∙ Uses European model terminal. Please note round terminals and Y-terminals cannot be connected.
∙ See website for other precautions.
