  • Page 2: Model Selection

    TF1500 series power supplies support RS 232/RS 485 UART control interface based on RXD/TXD TTL signals or I²C interface based on serial clock (SCL) and serial data (SDA) signals. Both allow control of functions such as ON/OFF control, output current limit and output voltage settings.
  • Page 3 • Switch off the main AC power before connecting the power supply. • TF1500 series are defined as Class I equipment. Use input wire compliant to the local electrical code for the AC input for this mod- el rating. The rating is listed on the product nameplate label.

  • Page 4: Mechanical Mounting

    The recommendation is to use cable lugs for proper and secured connection. TF1500 series power supply offer mounting options from the bottom and/or long sides of enclosure. Refer to the mechanical drawing in the datasheet for detailed dimensions. Use M4 screws with maximum penetration of 3mm measured from the enclosure surface.
  • Page 5 For the graphical user interface with the power supply a CT-251 module or similar can be used. Contact your local SLPE field applica- tions support for GUI user manual and for more details. Fig. 02: GUI Example. TF1500 Application Note v1019 Copyright © 2019 SL Power Electronics Corp.
