Jameco Makes Custom Power Supplies Available

September 11, 2006 by Jeff Shepard

Jameco Electronics announced that it now offers Mean Well's modular power supplies, giving users the flexibility of thousands of voltage-level combinations to meet a broad range of power requirements. Engineers benefit from a shorter time-to-market and reduced development costs. The power supplies consist of a front-end with Power Factor Correction (PFC) and multiple, user-specified, back-end dc modules. Using Zero Voltage Switching (ZVS) technology, the PFC stage rectifies the line current into high dc voltage (around 390Vdc). The ZVS technology minimizes the switching transient noise output from the converter, reducing power dissipation and improving efficiency.

The back-end dc modules are available in a combination of 75, 150 and 300W single-output modules or a 100W dual-output module. The modules transfer the operating voltage into outputs from 1.6 to 53V to suit different dc power needs. Units with five or seven slots accommodate up to 14 isolated outputs, each of which can be configured for a different voltage. The maximum output power is 1,000W.

"The modularity of this product line enables our customers to quickly and easily meet their specific power requirements, without having to obtain custom certifications," said Ray Bellantoni, Jameco's Director of Direct Marketing. The power supplies have worldwide ITE safety approvals and EMC certificates. The five-slot supplies measure 10" x 5" x 2.5"; the seven-slot versions are 7" x 7" x 2.5". The modular power supplies are custom-order items and usually ship within a week.
