The Cosel ACE300F is a modular power supply engineered for flexible, configurable multi-output applications. This 300 W platform accommodates up to four output modules, enabling up to twelve isolated outputs through its modular slot architecture. The unit accepts universal single-phase input (AC 85–264 V, 50/60 Hz) with active Power Factor Correction and complies with IEC 61000-3-2 harmonic attenuation requirements.
