With the SBU350 Series, SINPRO introduces a compact power supply designed for demanding applications in multimedia, IT, and control systems. The units deliver up to 250 W in fanless operation – and up to 350 W output power with external fan support.

An integrated 12 V output for fan operation is included as standard in all models. The power supplies are engineered for high operational reliability, energy efficiency, and full compliance with global safety and EMC standards.

Key technical features:

• Maximum power output:
  – 250 W convection-cooled
  – 350 W with active fan (12 V auxiliary output integrated)

• Wide input range: 90–264 V AC / 128–367 V DC

• Dimensions: 127 × 76.2 × 36.1 mm (3" × 5" × 1.46")

• Certified to:
  EN/IEC/UL 62368-1

• EMC compliance: EN 55032 (Multimedia)

• Material classification: UL94V-1 (Flame resistance)

The SBU350 Series is particularly suited for applications with modular cooling concepts, such as in industrial systems, digital electronics, or AV equipment – where a compact form factor and standards-compliant performance are essential.
