Custom Power Supply
The market is fast and volatile.
In this fast moving market, Tabuchi responds with the high speed engineering turn-around and high speed manufacturing ramp-up.


At Tabuchi, through extensive research s& development of the key coponents
especially magnetic devices=the key for the heart of switching power supply, the optimum design for switch mode power supply has been made and provided to the customers. Tabuchi SMPS design technology is the optimum combination of performance, material cost, production efficiency, logistic efficiency, and just-on-time (not JIT) delivery. Our production facility in China and Thailand feature high throughput as the power supply volume production center for high volume production.

I llustrated beneath is the custom power supply design flow at Tabuchi from Inquiry to Product Delivery.



The Custom Power Supply Flow Chart

STEP1:Inquiry
If you need high volume, high reliability, competitive power supplies, please inquire to Tabuchi at first.
It will take about one to four weeks from the inquiry to the initiation of the development.
1-4Week
STEP2:Development
We have been the major player for the game machines in Japan and cell phones. Also, Tabuchi has developed low profile SMPS with active filter for large screen LCD FPD as the major player. In Photovoltaic Inverter, Tabuchi is the leading company to have the No.1 market share in residential inverters.

The design of Tabuchi SMPS is backed with its long history more than a quarter century history with SMPS design and is supported by various CAE simulation tools.

The initial phase of development requires about one to six weeks to furnish first breadboard samples.

1-6Week
STEP3:Sample Submission
The samples are prepared per the request of customers ( budget, leadtime, specifications) . One to Two months are needed to furnish the initial working samples after the finalization of design specification.

In order to minimize the design time at the customer site, Tabuchi funishes the samples as close as the production model and to do this, Tabuchi works closely with customers as the member of Concurrent engineering team of the customer.It is expected that the time between initial samples to the production release is about four weeks to eight weeks.release

4-8Week
STEP4:Complete Production Model
After the production design is fixed, the submission of production sample takes place. Here the product is made by the same production process with the volume production and the same tool, ATE, jigs, and die are used.
1-3Week
STEP5:Reliability Test   STEP5:Safety Standard
In Tabuchi's design center, constant temperature chambers and various other testing equipment
are installed for the verification of the design integrity.


Reliability Test
  With its experience over 30 years of switching power supply, Tabuchi is fully capable of aquiring the safety approval of the world.
