Cosel Launches TU Series of Board Level AC-DC Power Supplies
Cosel Co. Ltd. has launched the TU Series of board level ac-dc power supplies. The TUNS50 and TUNS100 (50 & 100W) are available for immediate shipment. The TU series is a universal input PFC front end, and dc-dc converter combined in a single module. The TUNS50 comes in a compact 1/4 brick size and the TUNS100 comes in a 1/2 brick. This product was designed to reduce development time and board space requirements. Output voltages of 5, 12 and 24Vdc are standard. Output voltage can be adjusted using the standard trim pin if desired.

The TU Series can operate at 100% output up to 75°C at the base plate and 50% of the rated capacity at 100°C base plate temperature. The TU includes built-in over current protection, over voltage protection and thermal protection circuits.

Cosel Digital Bus Converters Feature Efficiencies up to 93%
Cosel has announced the “CHS series” high-power dc-dc converter family with double the power density of its previous-generation CES/CQS bus converter modules. The CHS family of isolated converters consists of an 80W sixteenth-brick and a 200W eighth-brick.

According to the company, the improvements in efficiency were achieved through proprietary synchronous rectification technology combined with microcontroller-based digitally assisted control. In addition to maintaining high efficiency over a wide range of load factors the CHS series meets IEEE802.3 Ethernet standard for 2250V input-to-output isolation.

Cosel Introduces Streamlined AC-DC Switching Power Supplies
Cosel Co. Ltd. launched its 300 & 600W, ac-dc switching power supply PLA series. The company states that its PLA Series is as reliable series as its existing high end PBA Series, the difference being that the cost profile in this series is substantially reduced. Cosel claims that for many applications such as LED sign, automation and test equipment, the cost savings is dramatic.

The PLA series has been designed with streamlined functions and smart circuits as a basic concept. All electrolytic capacitors have 105°C rating, and built-in fan lifetime is 50,000H at 60°C. Other features include, low 1U profile for the PLA300F 41mm, 1.61" and PLA600F: 61mm. Options also include Conformal Coating of outside use, low leakage current for medical equipment, input voltage dip to withstand semiconductor manufacturing requirements.

Cosel USA Introduces New Isolated DC-DC Converter Series
Cosel USA introduced its MG Series, a new generation of dc-dc converters which the company says combines high reliability and long life, with an industry standard 1X1 or 1X2 form factor. These 15 and 30W converters offer high power density and efficiency of up to 92%. The MG series is 30 to 40% smaller than the last generation, reducing the space required on the PCB. In addition the Cosel MG Series has 6 sided shielding. This means that valuable PCB space under the MG series can be used and no additional shielding is required. According to Cosel, other manufacturers only provide 5 sided shielding, which dictates that the space under the dc-dc converter must be shielded or void of traces.

In the course of use, surface mounted parts inside dc-dc converters can suffer mechanical stress resulting from changes in operating temperature. This can cause fatigue and cracks at the solder joints. Cosel uses a new soldering technique, along with a flexible potting material that significantly reduce stress on surface mounted components in the MG series, resulting in greater reliability and longer life.
