DC/DC modules feature floating dual outputs

Keywords:DC/DC modules? floating dual outputs? PKR modules?

Ericsson Power Modules has extended its MacroDens portfolio with three PKR open-frame DC/DC modules aimed primarily at powering telecom and datacom transmission systems that require floating dual outputs such as line cards and optical transmitters. The PKR modules will also power a wide range of applications in instrumentation and process control that use analog logic and communication chipsets. With their floating design, the devices' dual outputs can also be configured in series, making them suitable for many other applications.

The new products are the PKR4221A with a 'telecom input' voltage range of 36-75V with dual outputs (12V/0.62A), the PKR2221A "industrial" input voltage range of 18-36V with dual outputs (12V/0.62A), and the PKR4928A "telecom" input voltage range of 36-75V with dual outputs (3.3V/2.1A-5V/0.5A).

The PKR modules' 'board-to-board' assembly technology is a proven platform optimized for cost efficiency and ease of assembly, said Ericsson. Their floating dual outputs provide a flexible output range offering multiple combinations. The PKR is a 100-percent drop-in replacement for its predecessor the PKF, offering an easy migration from the molded PKF to the open-frame PKR when re-designing boards to comply with RoHS legislation, and other environmental requirements in the U.S. and Asia.

Moving from the molded MacroDens (PKF) to an open-frame design (PKR), the product is 50 percent lighter at 9g, which reduces additional costs related to packaging and transportation, and aids in the pick-and-place assembly process, said Ericsson. The PKR series is 100-percent compatible and interoperable with established MacroDens PKF modules.

Pricing is $9.90 cents in OEM quantities.
