500W DC/DC-konvertere til DIN-skinne montage

TDK lancerer under TDK-Lambda varemærket DDA serien af DC/DC-konvertere på op til 500W til DIN-skinne montage (in english).

TDK announces the introduction of the TDK-Lambda brand DDA series of DIN rail mounted DC-DC converters up to 500W output power. Using TDK-Lambda’s i6A non-isolated step-down power modules, these units achieve great efficiency up to 95%. They can accept a wide range DC input of up to 9 to 53Vdc and provide output voltages between 3.3 to 24V. The DDA units are buck-regulators, so any time the input voltage need to be at least 3V higher than the targeted output voltage.

The DDA series can provide cost effective, low voltage outputs from standard 12V, 24V ore 48V power supply outputs found in almost every industrial and test and measurement system. Typically, these systems use a common ground for all output voltages, so there is no need for isolated converters to generate additional output voltages.


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

Features include remote sense, remote on/off, plus an open-collector power good signal for each output. The dimensions of the DDA series are just 123.4 mm height, 115 mm depth and 36.5 mm width. This is the same shape like a typical 120W DIN rail power supply.

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.
