FAQs
for FSP500-50FDB 500W Flex ATX Industrial AC/DC Switching Power Supply
It provides multiple DC output rails typical for an ATX power supply, including +3.3 V, +5 V, +12 V, -12 V, and 5VSB. The +12 V rail carries the majority of the available power, while the remaining rails support logic, peripheral, and standby requirements.
The unit supports a full-range AC input from 90 V to 264 V AC, allowing operation across common worldwide mains supplies. It also features active PFC to improve power factor and overall efficiency.
The power supply is described as compliant with major international safety and EMC requirements, including IEC/EN 62368-1. It also carries UL/cUL, TÜV, and CCC certifications, and meets FCC Class B EMI requirements for broad professional deployment.
The FSP500-50FDB measures approximately 150 mm x 81.5 mm x 40.5 mm and follows the Flex ATX standard. This compact size is intended for 1U rack-mount chassis and other space-limited systems.
It uses an internal 40 mm fan mounted on the output side. The design is intended to provide effective cooling while helping minimise operational noise, although no specific acoustic rating is provided.
The FSP500-50FDB includes Over-Current Protection (OCP), Over-Voltage Protection (OVP), Over-Temperature Protection (OTP), and short-circuit protection. In a fault condition, the PSU shuts down to help prevent damage and can recover once the issue is resolved.
Yes. It is designed for demanding, continuous-use environments and is rated for operation from 0°C to 50°C at full load. Its MTBF of over 100,000 hours at 25°C and full-load burn-in at 50°C further support long-term reliability expectations.
Typical applications include 1U rack servers, telecom and networking equipment, embedded industrial computers, and automation controllers. Its compact Flex ATX footprint and 500W output make it a strong fit for systems that need substantial power in a limited space.
