What devices use a 550W fanless power supply?

These power supplies are ideal for telecom systems, industrial PCs, drones, medical scanners, ventilators, dental chairs, and more—anywhere space is tight, and reliability is critical.

Is it safe to use without a fan?

Absolutely. Thanks to baseplate conduction cooling and high efficiency (up to 94%), these 550W fanless power supplies run cool even without airflow—reducing noise and increasing lifespan. 

Real-World Applications

LFM550S – Industrial Focus

Telecom infrastructure

Remote kiosks & IoT hubs

Robotics & drones

Marine & substation gear

LFM550M – Medical Focus

Surgical lighting

Dental chairs

Medical monitors

CT scanners & portable X-ray machines

These 550W fanless power supplies are especially suited for portable or space-limited devices where traditional power supplies won’t fit.

Why Fanless Power Supplies Matter

Traditional fan-based power units:

  • Create noise
  • Require maintenance
  • Are more prone to failure due to moving parts

Cincon’s fanless design means:

  • Longer lifespan
  • Lower system noise
  • Zero fan maintenance
  • More flexible installation (no airflow required)

Future-Proof Your Power

As industries shift toward more efficient, compact systems, the demand for fanless, high-power-density AC-DC solutions is only growing. The Cincon LFM550 series is a platform for tomorrow’s innovations.
