● U bracket model with high efficiency and long life
● Single output models at 150 – 400 W available
● Mixture of connector model and terminal block model input / output connections
∙ 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.
∙ ESP31-150 does not support TÜV.
∙ Connectors to be connected to the input and output are sold separately.
∙ Please note that ESP31-150 does not have a DC output terminal block cover.
