DENSEI LAMBDA taking a part of Tel-Communication market in earnest!

Densei Lambda K.K. has been looking steadily at Tel-Communication Market for next generation and developed DC-DC converter “PA Family”; 1 type of high power & high efficiency full brick PAF series, 5 types of half brick PAH series, and 2 types of high performance & low profile dual output PAL series in order to expand DC48V input line up.
In addition, DC48V noise filter, MBS4850 has been developed for focusing on Tel-communication market.
Trough those developments Densei Lambda becomes the only a manufacturer in Japan who can fully cover power supply for Tel-communication by power module and noise filter.
Our DC-DC power module line up is extended 38 types, 273 models in total.

PAF Series;
1. Original ASIC in Control Circuit: actualized 90% of high efficiency, low
   noise, high power density, high cost performance by Zero Voltage
   Switching technology (ZVS)
2. Increase of Max. Output Power per volume by three (comparison to our
   former products) : 5.53W/cm3 
3. Safety Standards: UL1950, CSA950, EN60950 (applying)
4. CE Marking (Low Voltage Directive)
PAH Series;
1. Line up 50/75/100/150/200 types with 3 options each: 5 types 96 models
2. Safety Standards: Approved UL1950, CSA950 (C-UL), EN60950 (BSI)
   (200W type: under application)
3. CE Marking (Low Voltage Directive)
PAL Series;
1. Dual Output type (an example for the combination of output voltage: 
   1.8V and 3.3V etc.)
2. Low Profile, 8.5mm Height
3. In-Rush Current Protection Circuit provided
MBS4850;
1. Noise Filter specialized for DC48V Tel-communication application
2. Actualized in compact with low price by specially design for DC48V
3. Minimal size noise filter in the trade
4. Possible to modify (customize) to meet customer's application
