Cosel Featured Products

Cosel KH Series DIN Rail Power Supplies

Cosel KH Series DIN Rail Power Supplies come in 30W, 60W and 90W versions. The KH series features increased efficiency with synchronous rectification technology and resonant circuit over current/voltage protection, a wide operating temperature range, and NEC Class 2 for the 30 & 60W versions. The KH series has convection cooling and is specialized for DIN(35mm) rail products. The I/O terminals in the KH series are available in two types: Euro and Barrier Block styles.

Cosel TUHS Series AC/DC Converters

Cosel TUHS Series AC/DC Converters range from 3W-30W and achieve high efficiency and low standby power as well as greatly reducing size by low noise technology and soft switching circuits from Cosel's original technology.

Cosel MG Series DC-DC Converters

Cosel MG Series is a new generation of DC-DC Converters that combines high reliability and long life, with an industry standard 1X1 or 1X2 form factor. These 15W and 30W converters offer high power density and efficiency of up to 92%. The MG series is 30 - 40% smaller than the last generation, reducing the space required on the PCB. In addition the 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.

Cosel DHS Series DC-DC Converters

Cosel DHS Series DC-DC Converters offer high efficiency, high density, and high reliability. Features include built-in over current, over voltage, thermal protection circuits, and built-in remote On/Off and remote sensing. The series features an input range of 200VDC to 400VDC and output-voltage variations from 3.3VDC to 48VDC.


Cosel PLA Series AC-DC Power Supplies

Cosel PLA Series is an economical, enclosed type AC-DC switching power supply with harmonic attenuator and high efficiency. The PLA series has been designed with streamlined functions and smart circuits as a basic concept. For reliability, all electrolytic capacitors have a 105°C rating and a built-in fan. Lifetime is 50,000 hours at 60°C. The PLA series is suitable for many applications including LED signage, automation and test equipment.


Cosel PBA & PBW Series AC-DC Power Supplies

Cosel PBA & PBW Series AC-DC Power Supplies offer rugged durability and high quality with excellent power density. The PBA & PBW Series provides a high quality power platform designed to perform and maintain stable output voltage in stress conditions. From 10 watts to 1500 watts, the PBA & PBW Series comes standard with 12 single output models and 3 dual output modules. Cosel's proprietary thermal technology allows more efficient heat dissipation over smaller volumes, and considerable size reduction is also achieved by a reduction in board components, thereby reducing failure points.

Cosel LFA Series AC-DC Converters

Cosel LFA Series is a compact, light weighted, and wide input rugged PCB type AC-DC converter. Features include small and compact PCB construction, built-in inrush current, overcurrent and overvoltage protection circuits and universal input (AC85 - 264V). The LFA Series is compatible to worldwide safety standards including UL, C-UL, TUV standard and CE mark. With compatibility to various safety standards of major countries, investigation time and cost for safety standard accreditation can be reduced.


Cosel GHA Series Power Supplies

Cosel GHA Series Power Supplies offer high density up to 24.1W/inch³ max. with Industrial and Medical approvals. The GHA Series is available in 300W or 500W options, fits 1U applications and has a standard footprint of 3" x 5". Features include built-in power factor correction circuitry for decreased AC input capacity and built-in inrush current, overcurrent and overvoltage protection circuits. Safety agency approvals include UL60950-1, C-UL, EN60950-1 ANSI/AAMI-ES60601-1/CSA60601-1, and EN60601-1 3rd.
