DC-ATX PSU „Made in Germany“ – now with conformal coating

Conformal coating for maximum durability

With the conformal coating now applied as standard, Bicker Elektronik provides highly effective protection for sensitive electronics against environmental influences that can lead to corrosion or failures over time. The specially developed protective coating encapsulates the electronic assemblies and reliably protects them from high humidity, condensation, salt spray, dust, and chemical exposure. This makes the BEP-520C particularly suitable for applications in the oil and gas industry, chemical and process industries, food production, robotics, and mining. Wherever electronics are exposed to severe temperature fluctuations or harsh environmental conditions, the conformal coating enhances operational reliability and extends the service life of the power supply.

Designed for Industrial 24/7 Continuous Operation

The BEP-520C has been engineered with a clear focus on maximum reliability. The fanless power supply operates across an extended temperature range from -20°C to +70°C and is ideally suited for continuous operation in enclosed industrial PC systems. Its compact design allows installation in embedded PCs, industrial computers, and rugged systems requiring maintenance-free operation and long-term availability.

Polymer Capacitors for a 12+ Year Design Lifetime

Unlike conventional industrial power supplies, which use traditional electrolytic capacitors, the BEP-520C relies exclusively on high-quality polymer capacitors. These are characterised by high temperature resistance, minimal ageing and stable electrical properties throughout their entire service life. As a result, the power supply unit is designed to last for more than twelve years and ensures a reliable power supply even during 24/7 operation.

Energy-Efficient and Fanless

With a typical efficiency exceeding 90 percent, the BEP-520C operates with outstanding energy efficiency. Heat generated during operation is dissipated directly through an optimized thermal connection to the enclosure, eliminating the need for active cooling fans. This reduces maintenance requirements, prevents mechanical wear, and increases operational reliability in dusty or enclosed industrial environments. At the same time, standby power consumption remains below 0.3 watts, fully complying with the requirements of ErP Lot 6.

Reliable power supply for industrial PC systems

The BEP-520C features galvanic isolation between the input and output, with an isolation voltage of 3000 VAC. The regulated ATX output voltages (+3.3 V, +5 V, +12 V, -12 V and +5 VSB) reliably power modern industrial motherboards and do not require a minimum load. Comprehensive protection functions, such as short-circuit, overload, overvoltage and overtemperature protection, ensure the safe operation of both the power supply unit and the connected IPC system.

Rugged Industrial Quality for Extreme Requirements

The industrial PC power supply has been specifically designed for operation under high mechanical stress. A high-quality FR4 industrial PCB with plated-through holes, combined with a rugged mechanical design, ensures permanently reliable solder joints even under severe shock and vibration conditions. The BEP-520C complies with the requirements of EN 60068-2-27 (Shock), EN 60068-2-6 (Sinusoidal Vibration), and EN 60068-2-64 (Broadband Random Vibration). An integrated cable management system also enables the flexible use of customer-specific cable assemblies, while a matching DC cable set is included as standard.

Wide Range of Applications

The BEP-520C is ideally suited for fanless embedded PCs, industrial controllers, IPCs, and rugged computers used in demanding industrial environments. Typical applications include Industry 4.0, industrial automation, robotics, transportation, power generation and distribution, infrastructure, process industries, as well as oil & gas, chemical processing, food production, and mining. The new conformal coating option further expands the application range to environments with high humidity, corrosive gases, or chemical exposure.
