Certified according to EN/UL 62368-1:
Powerful industrial PC power supply with wide-range DC input

The DC IPC PSU BES-540C was developed for operation on +24 VDC networks. It is ideally suited for use in industrial environment, as well as in logistics and transportation. Due to the wide input voltage range from 20 to 36 VDC, the robustly constructed power supply unit is insensitive to strong fluctuations of the input voltage.

With an output power of 400 Watt, the BES-540C reliably supplies powerful industrial PCs and computers for image processing. The particularly robust Industrial PC power supply unit is designed for long-term 24/7 continuous operation. The BES-540C is characterized by a high efficiency of 81% and an extended working temperature range from 0°C to 70°C. The power supply unit can be started from a temperature of -20°C.

The BES-540C is certified according to the latest safety standard EN/UL 62368-1. The power supply unit has an earthing bolt for reliable equipotential bonding. The high quality of the components used and the excellent circuit design are reflected in a MTBF of more than 121,000 hours according to MIL-HDBK-217F at + 50°C WITH fan.

Powerful +12V ATX output with 30A for high-performance graphics applications

With a high current of 30A on the +12 VDC output, the BES-540C has enough reserves to reliably and safely supply particularly power-hungry graphics applications under industrial environmental conditions. Reverse polarity protection at the input as well as short circuit and overvoltage protection at the outputs ensure additional operational reliability. All outputs do not require any base load.

Our industrial PC power supplies with DC input are used worldwide in a variety of applications: Industry 4.0, automation, transportation, commercial and measuring vehicles, communication technology, energy, POS / POI systems, monitoring and security technology and many more.

Ball-bearing branded fan with temperature control and tachometer signal

The cooling - and thus the fan - is an important quality and reliability factor! That is why we only equip the BES-540C with fans from well-known brand manufacturers. The power supply units have a separate tachometer signal output for permanent function monitoring of the fan. This ensures the permanent availability of the supplied computer system even in demanding applications. The temperature-controlled fan also reduces the noise generated by the ball-bearing fan to a minimum.

FR4 board with through-hole plating and customer-specific adjustments

The high-quality printed circuit boards in FR4 industrial quality are considerably more dimensionally stable and more durable than inexpensive hard paper boards. The through-hole plating of the board ensures robust and permanent solder connections. Optionally, if desired, parts and components can also be fixed with a high-quality adhesive and thus protected against increased shock and vibration loads. Customized protective lacquer coatings are also possible.
