Why choose it

This power supply is built for reliability in demanding environments. Its active PFC reduces harmonic distortion and improves energy efficiency, while the integrated fan keeps temperatures stable even under full load. The 1U height allows installation in standard 19-inch racks, saving valuable cabinet space. With a wide input voltage range, it operates seamlessly across different mains standards worldwide.

Ideal use cases

• Industrial automation and control systems
• LED lighting and signage
• Test and measurement equipment
• Telecommunications and networking devices
• General 24 V DC applications requiring high power density

Good to know

The RSP-320-24 includes a built-in fan with ON/OFF control, which reduces noise when the load is light. Its hold-up time of 16 ms at 230 V AC helps bridge short power interruptions, and the isolation voltage of 3 kV AC between input and output ensures safety. The unit is backed by a mean time between failures (MTBF) of over 200,000 hours, calculated per MIL-HDBK-217F at 25 °C.
