Electrical Power & Protection
Emerson Network Power is offering its newest generation high-power, half-brick, integrated DC/DC converters - the Astec AIH-300Vin Series from Astec Power ( www.astecpower.com). With power density up to 5,5 kW/litre, the new devices can deliver up to 250 W of output power from an input range of 250 to 420 V d.c. The series includes six models with single-output DC voltages of 1,8; 3,3; 5; 12; 15 and 24 V. Suitable for communications, industrial, non-patient connected medical equipment and ground base military applications, the devices are especially appropriate for compact enclosed systems and outdoor environments.
Beyond the significant advances in power density, the new AIH-300Vin Series offers embedded functions that will provide additional benefits to end-users. The new converters provide an extensive set of embedded functions that include monitoring, protection, and adjustment capabilities as well as a communication bus that can store valuable user information that eliminates the need for designers to create these features externally on the circuit board. This flexibility frees up board space and allows for future increases the density of the design.
The new series can be operated over a wide base plate temperature range from -40°C up to 100°C while reaching 88% efficiency at 5 V output. Key embedded functions include: current sharing, enable (positive and negative option), output voltage adjust; clock-in (for synchronisation in parallel application), temperature monitoring and output current monitoring. With increasing needs for storing and communicating significant end-user information, the devices also include an I2C Interface to an internal EEPROM for data storage. In addition to these monitoring and control functions, the new AIH-300Vin Series offers a number of reliability safeguards such as overtemperature, overvoltage and overcurrent protections.
Designed with state-of-the-art components, the AIH-300Vin Series employs a fully surface mount design that simplifies manufacturing while enhancing quality and reliability. As with all of Astec's DC/DC products, the AIH-300Vin Series meets international performance and safety standards including those from UL, cUL, TUV and CE. The 1,8; 3,3 and 5 V output models are available now, while the 12 V, 15 V and 24 V output models will be available in July this year.
