The DDA DIN rail mount, non-isolated step-down converters are ideal for creating additional high current output voltages from a single output 12V, 24V or 48V AC-DC power supply.
Available with a choice of single (250W) or dual output (325W and 500W) models, the highly efficient modules accept a wide DC input from 9V up to 53V to accommodate multiple industrial and test and measurement applications and reduce in-house stock. The wide 3.3V to 24V output adjustment accommodates non-standard voltages.
Standard features include remote sense and remote on/off, plus an open-collector power good signal for each output. The DDA series is highly efficient, up to 95%, reducing internal heat for increased reliability. All models are 123.4mm high, 115mm deep with a very narrow 36.5mm width, which allows more space on the rail for other devices.
All models in the DDA series are safety certified to IEC/EN/UL 62368-1 and are CE marked for the Low Voltage, EMC and RoHS Directives. The units also comply with EN 55032-A conducted and radiated emissions and meet the EN 61000-4 conducted, radiated and magnetic field immunity standards.
