NEW SWITCHER EMPLOYS ADVANCED ARCHITECTURE TO PROVIDE SIX
OUTPUTS
AT 600 WATTS IN 1U-HOT SWAP WITH I2C
Coral Springs, Florida-UNIPOWER's
new PowerCassetteŽ multi-output switching power supply employs a unique,
new cellular architecture (rather than modular) that permits quick factory
programming of its outputs to meet virtually any requirement. The unit provides
up to six outputs, including a 5VDC, 1-ampere independent standby. Maximum
continuous power is 600 watts; available output voltages are from 1.2VDC to
24VDC. This advanced design supersedes the older "modular" type architecture
and provides features targeted at today's networking, storage and communications
systems. The design provides a customer-configured, agency-approved power
supply in short order without NRE charges or delays.
PowerCassette uniquely
anticipates the likely hierarchy of voltages and currents plus the "bells and
whistles" demanded by 90% of typical networking, storage and communications
requirements in the 400-600 watt power range. This design-for-manufacturability
approach offers the immediacy of the building block concept with the small size
and reduced cost benefit associated with a full custom design.
Significant features of the PowerCassette
include an ultra-compact, low profile case measuring 1.6 inches high, 5 inches
wide and 11 inches deep, giving 6.8 watts per cubic inch power
density, a breakthrough in multi-output design.
Integral ball bearing fans cool the unit. Other key features
include a single input/output connector for hot-swap applications, output ORing
diodes and single-wire current sharing. Power factor correction, Class B EMI input
filter, remote sensing, worldwide AC input range, no minimum loads and
adjustable outputs are all standard features built into this product. With the
exception of power components, PowerCassette consists almost entirely of
high-density, surface-mount components.
A notable feature, optionally available on PowerCassette,
is an I2C serial data bus output, which provides for real-time monitoring of
output voltages, output currents, internal temperature and fan speeds. This
feature is available to interface with the host system through an available
standard 1U, 1+1 redundant rack or directly from the output connector on the
power supply.
PowerCassette's proprietary
architecture employs four standard internal power cells: one for the input
filter, rectifier and power factor converter, and three others for
pre-configured single and multi-output DC-to-DC converters. For a given
requirement each specified output is assigned at the factory to the optimum
DC-to-DC converter cell, which is then programmed to the specific output
voltage. The power cells provide two high-current, one medium-current and two
low-current outputs.
The key advantage of PowerCassette
is fast time-to-market with a final, flexible and cost-effective power
solution. PowerCassette eliminates the cost burden of modular designs while
retaining the flexibility.
Pricing for PowerCassette in OEM quantities is as low as
$399 each. Delivery is 5 to 10 days for prototype quantities and 8 to 10 weeks
for production quantities.
UNIPOWER Corporation designs,
manufactures and markets high-density/hot-swap power solutions for
telecom, datacom, workstations, networks, servers, data storage, industrial and
medical systems.
