Power supplies offer a +50% boost power rating

TDK Corporation announces the addition of higher power, three-phase AC input models to the TDK-Lambda DRB series of DIN rail mount power supplies. With 24V, 48V and 72V outputs, the products are rated for continuous operation at 480W or 960W and can deliver a boost of 720W and 1440W respectively for up to seven seconds.

This, and a constant current overload characteristic, enables operation with capacitive and inductive loads. These power supplies also feature a very low energy inrush current upon initial start-up, reducing nuisance tripping of input circuit breakers. The DRB three-phase series can be used in a wide range of applications, including conventional switch cabinets, stand-alone machinery and industrial systems, as well as information and communications technology.

The units have a wide input range of 350 to 575Vac and are housed in a rugged metal enclosure with dimensions of 65mm (width) x 129mm (height) x 159.3mm (depth) for the 480W models and 100mm (width) x 129mm (height) x 171.9mm (depth) for the 960W. This saves space on the DIN rail for other components and reduces cost. A choice of screw terminals or push-in connectors are available for the input and output wiring.

The DRB480 and 960 models have a high operating efficiency of up to 96.3% and a low stand-by power consumption of xtagstartz2.3W when using the remote on-off function (inhibit). This reduces energy usage and contributes to a lower CO2 footprint of the entire system. Lower losses also reduce internal heating inside the power supplies, preventing electrolytic capacitor dry-out for long field life.
