Chongqing Tuopu Electron Co., Ltd
We are a manufacturer, not a trading company. One plant, one product category, and the engineering team that designs it: isolated DC-DC and AC-DC power modules, built and tested at a single address in Yubei District, Chongqing since 2005.
| Custom Work | OEM & ODM |
| Isolated AC-DC | 2 W – 200 W |
| Isolated DC-DC | 0.25 W – 2 kW |
| Footprints | SIP · DIP · SMD · Brick |
| Isolation Ladder | 1,500 – 15,000 VDC |
Model counts and electrical limits are measured from the same product database our engineers quote from.
AC-DC & DC-DC Converter Manufacturers
Chongqing Tuopu Electron Co.,Ltd
Chongqing Tuopu Electron Co., Ltd is a module power supply manufacturer registered and operating at No. 399, Taoyuan Avenue, Shuangfengqiao Street, Yubei District, Chongqing, China. The plant, the engineering office and the test laboratory share that address, and the company has been building power conversion products there for more than twenty years.
Two families cover the whole business: module power supplies and switching power supplies. Isolated AC-DC converters run from open-frame boards to fully enclosed units. Isolated DC-DC converters span SIP, DIP, SMD and brick footprints, including high-input bricks for a bus voltage well above the rail being generated, plus a dedicated solar / PV series for string voltages.

Four Decisions That Have Not Changed in Twenty Years
Most suppliers describe what they sell. These four positions decide how this company behaves when a specification is difficult or a deadline moves.
1
One category, and nothing adjacent
Module power supplies and switching power supplies have been the entire product range for two decades. The company has not spread into unrelated electronics to make a catalogue look wider, which is why a question about your input window is answered by the engineer who designed around one.
2
One site, from solder paste to packing
Solder-paste printing, placement, through-hole insertion, wave soldering, assembly, automatic potting, ageing and final test all happen inside the same building. Nothing critical is handed to a party the company cannot walk over and audit.
3
Components chosen by specification, not by price
The majority of the bill of materials comes from established international brands. Cheaper sourced parts are the fastest way to lower cost — and the fastest way to lose the isolation rating or the thermal margin that made the module worth buying in the first place.
4
An intent to still be here
The stated aim is a long-term relationship rather than a single shipment: consistent part numbers, a stable test route, and a factory you can visit instead of a trader you cannot reach. Twenty years in one category is the only credential that cannot be printed on demand.
Two Names on the Paperwork
A supplier audit asks whose system was certified and whose name is on the patent. That is not always the company that ships the carton, so we state it plainly instead of leaving you to discover it during the audit.
Chongqing Tuopu Electron Co., Ltd
The company that designs, assembles, pots, ages and tests the modules, and the entity you contract with and pay. Every quotation, datasheet, order and shipment on this site belongs to this company.
Guangzhou Aipu Electron Technology Co., Ltd
The entity named on the certificates, patents and third-party test reports reproduced on this page. We publish each one with its certificate number, validity period and tested models so that it can be checked against the issuing body independently of anything we say.
Certificates & Compliance
Company-level systems and product-level compliance are separate hings, and we list them as such. Certificates are available as high-resolution files; compliance test reports are available on request.
From Requirement to Mass Production
Four steps, one engineering contact. Custom projects do not disappear into a sales queue - the engineer who reviews your specification is the one who signs off the sample.
01.
Share Requirements
Input/output voltage, power, isolation, package, application and certification needs.
02.
Engineering Review
Our engineers confirm feasibility, select the topology and return a quotation.
03.
Sample Build
Pre-production sample for your bench test and approval.
04.
Mass Production
Volume production with 100% functional test and ageing.
