Know before you buy
Yes, the RSP-500-12 features a universal AC input range of 85~264VAC, allowing it to operate reliably anywhere in the world without needing manual voltage switching.
Yes, it is designed with a 1U low-profile form factor measuring 40.5mm in height, making it ideal for space-constrained rackmount environments.
The unit uses forced air cooling via a built-in DC fan to maintain optimal temperatures. While it is efficient for high-performance tasks, the fan will generate audible airflow noise, which is standard for active cooling in industrial-grade power supplies.
The power supply includes a comprehensive protection suite that guards against short circuits, overloads, over-voltage, and over-temperature conditions to ensure both the unit and your connected equipment remain safe.
The remote sense feature compensates for voltage drops across long cables to ensure accurate output at the load, while the remote ON/OFF control allows you to manage the power state of the unit externally without cutting the main AC power.
It is rated for operation in temperatures ranging from -30°C to +70°C, making it highly versatile for demanding industrial or outdoor enclosure applications.
