The DC3 & DC3-T series are isolated DC-DC converters with a wide 3:1 input voltage range of 300V to 900V and output power up to 50W. These modules have shutdown feature and continuous short-circuit protection. The compact size has threaded inserts to mount securely for high vibration and shock applications. Conduction cooling is available through the baseplate or compatible heat sink. • Wide 300V to 900V input range • Input/output isolation • Sense feature • Shutdown feature • Short-circuit protection • Through hole or terminal strip • Fixed operating frequency • No external components required 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, Isolation Voltage or Output Power BLANK = THROUGH HOLE T = TERMINAL STRIP
