The Perfect Blend of Performance and Affordability in a 480W Three-Phase DIN Rail Power Supply LITF480-26BxxS Series

The Perfect Blend of Performance and Affordability in a 480W Three-Phase DIN Rail Power Supply LITF480-26BxxS Series.jpg

MORNSUN provides the most suitable DIN rail power supplies for different application scenarios. The standard LI series with plastic and metal casings can be used in general industrial environments, while the 120-960W high-reliability LIMF, LIHF, and LITF series are suitable for high-end applications. For stringent operating conditions and also require cost consideration, it is recommended to choose the 480W three-phase DIN rail power supply - LITF480-26BxxS.

By eliminating some non-essential features, such as RS485 communication function, from the LITF480-26Bxx, this NEW series strikes a balance between performance and cost, offering a reliable and affordable solution.


Wide input voltage range: 3 x 320-550VAC (transient 600VAC) or 450-800VDC (transient 845VDC) 

High performance

① High efficiency of up to 95%, Active PFC, PF up to 0.95

Operating temperature range: -40℃ to +70℃ (full load @50℃), suitable for the complex temperature environment

150% peak power lasts for 3s, and supports the starting of heavy loads such as DC motors or capacitive loads.

③ Output short circuit, over-current, over-voltage, over-temperature protections

High reliability

Conformal coating protection on each PCB side, provides protection in dust or outdoor applications

Isolation voltage of 4000VAC, provides protection in applications with high voltage requirements

③ The heat dissipation structure is a dual-channel design of cold and hot separation to achieve better heat dissipation and higher reliability
