The AC series are isolated AC to DC power supplies with integrated power factor correction. The space saving 4.6” x 2.5" x 0.8" full brick can power up to 300W. Output voltage models ranges from 5V to 300V. The combination of front end PFC module and isolated low voltage output saves space -one module instead of two modules. • Single or three phase input • 300W output power in a full brick size • Input/output isolation • Regulated 5V to 300V output models • Output sense feature • Fixed operating frequency Contact Pico for part number of available options: • Expanded operating temp: -40°C to +85°C Stabilization Bake Temperature Cycle Burn-In • Special Input Voltage, Output Voltage, or Output Power *AC3, Three Phase input only. See Series UAC for Single Phase input and >100V output models
