DDA - DC-DC DIN rail power supplies with up to 250 W per output

TDK-Lambda announces the introduction of the DDA series of DIN rail mounted DC-DC power supplies. Using TDK-Lambda’s i6A non-isolated step-down power modules, the units can accept a wide range DC input of up to 9 to 53 Vdc and provide output voltages between 3.3 to 24 V. The DDA series can provide cost-effective, low voltage outputs from standard 24 V AC-DC DIN rail power supplies found in many industrial and test and measurement systems.

The DDA series has three standard models – a single output rated at +12 V at 20 A (adjustable from 3.3 to 15 V), and two dual outputs versions rated at +12 V 20 A / +5 V 20 A (both adjustable from 3.3 to 15 V) and +12 V 14 A / -12 V 8 A (both adjustable from 3.3 to 24 V). The available output power is typically 250 W for the positive outputs and 75 W for the negative output. The overall power rating with convection cooling is 250 W or up to 500 W with forced air cooling.

Features include remote sense, 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.

All models 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.
