The RDC20 and RDC40 series of 20 and 40 W metal encapsulated wide range DC-DC converters from XP Power are designed for railway and industrial applications. These highly efficient PCB mounted converters, typically 90%, comply with railway and rolling stock EMC standard EN50121-3-2 and can accommodate a wide range of input voltages. Both series are available with either a nominal input of 72 VDC (range 36 - 140 VDC) or 110 VDC (range 55 - 176 VDC).
Combined with their small size, the RDC20 measuring only 1.0 x 2.0 x 0.4 inches (25.4 x 50.8 x 10.16 mm), and a high efficiency, the RDC20 and RDC40 offer a high power density with minimal wasted heat. Both series can be used over the extended temperature range of - 40°C to + 85°C and can operate to full power using convection cooling up to + 50°C or up to + 60°C with an optional heat sink. Maximum case temperature is + 105°C.
Both series are available with either single or dual outputs. Single output models are available with + 3.3, + 5, + 12 or + 15 VDC. Duals comprise ±12 or ±15 VDC outputs. The RDC20 also has a ±5 VDC dual output option.
Standard controls and signals include remote On/Off, output over voltage, input under voltage and over current protection. An output trim function provides ±10% adjustment from stated nominal output on single output models only.
Basic input to output isolation is up to 1500 VAC and input/output to case is 1600 VDC. The RDC20 and RDC40 series complement the existing line up of RDC30 30 Watt converters.
The RDC20 series is priced at $70.20 for 500 pcs orders and is available from Newark, Digi-Key, or direct from XP Power and come with a 3 year warranty.
