PRODUCT OVERVIEW The UAC series are isolated AC to DC power supplies with integrated power factor corrections. The low profile 4.6” x 2.5" x 0.5" full brick can power up to 250W. 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. FEATURES • 0.99 Power Factor • Wide input voltage range • Up to 250W output power in a full brick size • Input/output isolation • Regulated 5V to 300V output models • 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 SERIES NOM.
