TDK Corporation announces the introduction of the 400 to 750W rated RGB series of ruggedized non-isolated DC-DC converters from TDK-Lambda. These converters operate from input voltages of 9 to 18V, 18 to 32V, or 18 to 60V and can deliver output voltages adjustable from 0.8 to 8V or 3.3 to 24V with output currents of up to 60A, depending on the power level. They are designed for harsh environment applications, including medical, automated guided vehicles (AGV), industrial mobile robots (IMR), drones, commercial off-the-shelf (COTS) products, industrial uses, test and measurement equipment, and battery-powered devices.With efficiencies of up to 98.5%, these converters deliver high usable power in demanding thermal environments, with case temperatures ranging from -40°C to +115°C, while also providing longer battery life. Featuring a 1/16th brick pinout and measuring 38.1 x 49.5 x 13.0mm (WxLxH), the converters are encapsulated to meet MIL-STD-810G standards for shock and vibration performance. The five-sided aluminum case reduces radiated EMI and allows for conduction cooling to a cold-plate for fanless operation.
Basic features of the models include an output voltage adjustment pin, negative logic remote on-off, remote sense, input under-voltage protection, over-current protection, and thermal protection. An optional adjustable current limit is available to reduce stress on the input source, converter, and load during overload conditions.
All models carry the CE and UKCA marks for the Low Voltage and RoHS Directives and are designed to comply with IEC/UL/CSA/EN 62368-1 safety standards. Evaluation boards are available for quick and easy testing.
