DIN-rail power supplies keep cool, says TDK-Lambda
DIN-rail mounted DC/DC power supplies in the DDA series from TDK-Lambda are i6A non-isolated step-down power modules with a wide range DC input (up to 9.0 to 53V DC) and provide output voltages between 3.3 to 24V.
The DDA series can provide cost-effective, low voltage outputs from standard 24V AC/DC DIN-rail power supplies found in many industrial and test and measurement systems, said TDK-Lambda.
There are three standard models. There is a single output model, rated at +12V at 20A (adjustable from 3.3 to 15V). The two dual outputs versions are 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 DDA series is efficient, up to 95 per cent, reducing internal heat for increased reliability. All models are 123.4mm high and measure 115 x 36.5mm.
All models are 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.
Electronics company, TDK, is based in Tokyo, Japan. It was established in 1935 to commercialise ferrite. TDK’s portfolio consist of passive components such as ceramic, aluminium electrolytic and film capacitors, as well as magnetics, high-frequency, and piezo and protection devices. There are also sensors and sensor systems such as temperature and pressure, magnetic, and MEMS sensors.
TDK also provides power supplies and energy devices and magnetic heads. Products are marketed under the product brands TDK, Epcos, InvenSense, Micronas, Tronics and TDK-Lambda. TDK focuses on demanding markets in the areas of information and communication technology and automotive, industrial and consumer electronics. The company has a network of design and manufacturing locations and sales offices in Asia, Europe, and in North and South America.
TDK-Lambda supplies reliable power conversion products for industrial and medical equipment worldwide.
