PRODUCT OVERVIEW The DC1, DC2A & DC2B series are isolated DC-DC converters with a wide selection of input voltage ranges from 120V to 1200V and output power up to 300W. These modules have sense feature to accurately regulate the voltage at a remote load. Input is protected against reverse polarity. The full brick case size has threaded inserts to mount securely for high vibration and shock applications. Conduction cooling is available through the baseplate or compatible heat sink. FEATURES • 120V to 1200V input range models • Input/output isolation • Remote Sense feature • Input reverse polarity protection • 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 INPUT VOLTAGE RANGE NOMINAL OUTPUT VOLTAGE

Series DC1 · DC2A & DC2B High Power DC-DC TYPICAL CONNECTION CIRCUIT ≥ 100V OUTPUT MODELS SENSE - ≤ 48V OUTPUT MODELS REMOTE SENSE LOCAL SENSE VOUT = VLOAD + VWIRE 1 + VWIRE 2 VLOAD = VOUT - VWIRE 1 - VWIRE 2 The positive remote sense (+SENSE) should be connected to the positive output (+VOUT) at the physical load location. The negative remote sense (-SENSE) should be connected to the negative output (-VOUT) at the physical load location. VOUT may compensate up to 1V of drop in the load wires. Voltage will be regulated at the load. Alternatively, for local sense, +SENSE should be connected to...
