Cosel PBA300F-24 AC Power Supply

The Cosel PBA300F-24 is a 300W AC-DC enclosed chassis-mount power supply engineered for industrial and embedded systems requiring compact, high-density power delivery. This unit accepts universal AC input (85–264V, 1Φ, 50/60 Hz) or DC input (120–350V) and delivers 24V DC at 14A nominal output. Measuring just 170 × 102 × 42 mm, it occupies 35–65% less volume than conventional 300W alternatives, making it ideal for space-constrained installations. The supply incorporates built-in power factor correction, harmonic attenuation compliant with IEC61000-3-2, and fan-cooled thermal management across the –20 to +71°C operating range.
