TBF500 Series

Full-Brick AC-DC Power Supplies: 500W

The  TBF500 AC/DC power supply series in a fully encapsulated full-brick package with up to 93% efficiency. For high operating temperature applications, the module can be mounted on the system chassis to dissipate its heat or equipped with the optional heatsink.

TBF500 series has a universal input voltage range of 85-264Vac. The output voltages are 12V, 15V, 24V, 28V, 48V, and 54VDC and are adjustable by external resistors in the range of +10%/ -10%, The use of the remote sense pins compensate  the voltage drop over the PCB tracks for an accurate working voltage at the point of load. The full protection functions include over-cur- rent protection (hiccup mode), short-circuit protection (automatic recovery), and output over-voltage protection (latch-off).

Compact & Simplified Design

To simplify the design and to save space on the PCB the TBF500 DC Power Supply module needs only a few external components to comply with the EMC Standard EN/IEC 50032, Class B, inrush current limiter function, and OVC III (over-voltage category). Additionally, the optional current share function, a maximum of 3 modules, can be connected in parallel to increase the output power.

The board mount type with only 12.7mm height makes this power supply ideal to install in systems with limited space. The form factor and base plate cooling are seen as a countermeasure to heat generation, allowing this power supply to handle rugged applications in demanding environments.

A module for high temperature applications

TBF500 Series allows a baseplate operating temperature of -40 to +105°C. It is designed for challengin operating conditions and provides high reliability to a variety of equipment such a 5G communication, ESS, defence, robotics and factory automation.
