DIN rail mount dc-dc converters deliver up to 250W per output

March 25, 2020  Stephen Law

TDK-LAMBDA AMERICAS DDA series DIN rail mount dc-dc converters use step-down non-isolated power modules that operate from an input range of 9 up to 53Vdc, with a wide adjustable output voltage range of 3.3 up to 24V. Units are suitable for generating additional low cost, high current outputs from an existing 24V bus in industrial, semi fabrication and test and measurement equipment. Three models are available, including a single nominal output +12V 20A, a dual output +12V 20A / +5V 20A and a dual output +12V 14A / -12V 8A. Output power is typically 250W for each of the positive outputs and 75W for the negative output. Convection cooled the overall output power is 250W, which can be increased to up to 500W with forced air cooling. Positive remote sense, remote on/off and individual power good signals are fitted as standard.
