Cosel PBA600F-24 Power Supply

The Cosel PBA600F-24 is a 600W AC-DC power supply delivering stable 24V DC output at 25A for industrial control systems, automation platforms, and distributed power architectures. Built with universal input spanning 85–264V AC (47–63Hz), it combines active power factor correction with >90% efficiency and convection cooling. The unit integrates comprehensive protection circuits - overvoltage, overcurrent, short-circuit, and over-temperature - alongside low output ripple (≤100mVp-p) and tight line regulation (≤0.5%), making it suitable for applications demanding precision DC rails in harsh thermal and electrical environments. Housed in a compact chassis-mount form factor approximately 125mm × 65mm × 220mm, this supply meets international safety and EMC standards including UL60950-1, EN62368-1, FCC Part 15 Class A, and IEC61000-4 immunity profiles.
