New Full-Brick Power
Module
High Power Density & High Efficiency |
PAF700,
world standard full-brick type power module for newest
mobile telecommunication BTS of next generation
Six requirements on BTS of next generation
''Compact, high power density,
high efficiency, wide range temperature, wide range
output voltage, withstand high voltage'' |
|
|
| Densei-Lambda
has developed new full-brick power module of high power density
and high
efficiency suitable for requirements on mobile telecommunication
BTS(W-CDMA,CDMA2000) of
next generation and mass production will be started from 2003.Jan. |
| 1. MKT background |
| Recent Economic
environment of IT and telecommunication industry is severe, however
mobile telecommunication BTS of next generation is developed aggressively
in the world.
Transmitting power of BTS increase to serve wide area every year.
Therefore high power density
power module is demanded and big sales to BTS manufacturer in North
America, Europe, Japan
and China are expected. |
| 2. Required specification on BTS of
next generation and feature of new full-brick |
Newest required specification of power supply
for mobile telecommunication BTS of next
generation is getting severe and severe. |
- Compact size for high density of BTS
- High power to serve wide area
- High efficiency for environment protection
(less energy, less heat)
- Wide range operating temperature suitable
for high temperature cold district
- Wide range adjustable output voltage to
drive amp elements at efficient voltage
- Withstand high voltage between input and
output of BTS
|

Densei-Lambda has developed
and will sale 700W power module of world standard suitable for
these requirements. This is the first 700W module in the world that
meets these all requirements. |

| 3. Sales strategy |
| Densei-Lambda
makes more effort to develop power module and provides various products
as
the top of Japanese standard power supply manufacturer. Moreover
Densei-Lambda does
worldwide sales through Invensys group for demand from IT and telecommunication
manufacturer.
The main customer for PAF700 is telecommunication manufacturer
of North America, Europe,
Japan and China. PAF700 will be manufactured in Senai factory (Malaysia)
and it will be sold
world simultaneously and 20 billion Japanese yen of sales are expected.
In addition, new power module for small BTS to serve small
and middle size district is under
development and sales will be spring in 2003. |
