Fast factory programming for six-output switcher

Unipower has introduced a new version of its popular PowerCassette, 1U, 600W, six-output switcher, which has its outputs factory set using internal DIP switches.

Unipower has introduced a new version of its popular PowerCassette, 1U, 600W, six-output switcher, which has its outputs factory set using internal DIP switches.

By this means, Unipower can offer next-day delivery on 234 different models, in small quantities.

The product, designated as the Quick-Set PowerCassette with model numbers starting with PCH-S and TPCH-S, comes in both chassis mount and hot-swap versions.

Specifications are identical to the current nonprogrammable version of the PowerCassette.

The units provide up to six outputs, including a 5V DC, 1A independent standby output.

Maximum continuous power is 600W, and available output voltages are from 1.8 to 12V DC.

The ultra-compact, low-profile case measures only 44 x 127 x 280mm, producing 6.8W/in3.

The case incorporates internal cooling fans and a single, pluggable connector.

Because the Quick-Set PowerCassette ensures rapid delivery it makes older, bulky and costly "modular" designs a less convenient option for multioutput applications requiring 400 to 600W.

The DIP switch output programming is the result of an advanced "cellular-type" architecture employing four standard internal power cells.

Patents are issued and pending on the Quick-Set PowerCassette.

Other features of the Quick-Set PowerCassette include power factor correction, single-wire current sharing, output ORing diodes on the hot-swap versions, remote sensing, adjustable output voltages, no-load operation, universal input range of 85 to 264V AC, overvoltage protection and overtemperature protection.

Input and output control and monitoring features are also incorporated.
