Transformer & Power Supplies
Helms-Man Industrial Co Ltd produces chargers, adaptors and transformers for markets in the US and Europe
Reliability is the key to quality transformers and power supplies and no one knows it better than the army of manufacturers in Hong Kong who have long powered the world.
Take manufacturer and exporter Sandan Ltd, for example, which was established in 1992 and has since built its business to reach a turnover of US$10m a year.
"More than anything our success is down to reliability, our very experienced R&D department and our flexible and efficient service," claims marketing manager Tony Lo. "Our response time is also very fast - for example, we will always answer any queries from our European customers overnight so they get the information they need first thing."
Among its extensive range are the SPA-D and SPA-W series desktop and wall mountable chargers with power ranges from 5W-50W and the SLC-BC-024 series switching 3.3Ah-26Ah lead acid battery chargers.
The firm also produces the BC-024 series for power tool chargers, drill/drivers and rechargeable battery chargers in various sizes ranging from 9.6V-24V, as well as European and UK adaptors.
Sandan produces 500,000 units per month at its 3,500-square-metre, 300-worker factory on the Chinese mainland. It has a minimum order requirement of 500-1,000 pieces and will deliver within 2-3 weeks of confirmation of order.
"Our reputation for quality has spread by word of mouth," claims Lo. "A majority of our customers are in Europe and the US and our products all have TUV, UL, CE and CSA approval where necessary."
Another manufacturer with an excellent reputation is Gauss Electronics Co Ltd, which sources bobbins, enamelled copper wire, ferrite cores and polyester tape from the mainland, Japan, Taiwan and Germany to produce trigger, choke and toroidal coils, transformers and line filters.
Established in 1983, it now produces 100,000 pieces per model each month across its full range with production split between two mainland factories in Dongguan that offer a combined area of 3,500 square metres and a workforce of 600.
"We were one of the first manufacturers of high frequency transformers and trigger coils in Hong Kong and we have kept some of our customers for a very long time," explains executive secretary Silon Tang. "They come back to us because our strict quality control systems ensure very high standards and our service is very professional."
Prices for Gauss products, which meet all the necessary requirements for UL, CSA, TUV and CE certification, are available on request from the ISO 9000-certified manufacturer.
The company has a minimum order requirement of 1,000 pieces per model and exports to the US, Europe and Japan, as well as Singapore, Malaysia and the mainland.
Gauss also manufactures on an OEM basis, notes Tang. "Our customers can submit technical specifications and we will get back to them with a sample within seven days depending on what is required," she explains. "Once the sample is approved we will deliver within four weeks."
Matsuta Co Ltd is equally experienced, having also enjoyed more than 20 years in the electronic components industry since it was founded in 1982. It carries about 2,000 types of standard transformers, inductors and coils, which are manufactured at two plants on the mainland employing a workforce of more than 1,000 with an annual output of 350 million pieces.
Prices are available on request and minimum order size depends on the individual product, but Matsuta claims it is also able to meet any unique requirements a customer may have.
"We can supply virtually any electrical transformer and our research and development department ensures we are up to date with the latest developments," says sales manager Lawrence Lee.
Some 70% of Matsuta products, which use ferrite cores, steel laminations and wire sourced from the mainland and Taiwan, are sold on the local market, with the rest exported to Europe and the US.
"We are committed to total customer satisfaction," Lee insists. "Our factories have ISO 9001 certification, our quality control is extremely high and our prices are competitive."
A relative newcomer to the power supplies market is Speedmark Enterprises Ltd, which was established in 1999. "We manufacture and export between 300,000-400,000 adaptors and linear type transformers each month for computer, toy and household electronic manufacturers around the world," says marketing executive Pamela Wong. "Our quality meets all international standards, including UK, CUL, CE, CB, ENEC and SEV, and our factory has ISO 9001 certification."
The company manufactures its own Speedmark brand range on the mainland in Shenzhen at a 3,000-square-metre facility with 120 employees, and will also customise to client specifications.
Speedmark, which exports to the US, Germany, Australia, Italy and the Netherlands, has a minimum order of 1,000 pieces and promises delivery within two weeks of order confirmation.
This prompt delivery and willingness to meet customer requirements means it's little wonder that the world has come to depend upon high quality, competitively priced and extremely reliable transformers and power supplies from Hong Kong.
