New Gen Ultra-Compact, High Efficiency Power Supplies for Industrial By COSEL

Responding to market demands for smaller footprints in industrial application – a new generation of highly compact power supplies for industrial applications, the TE series launched by COSEL.

The new COSEL TE Series are powered by wide bandgap Gallium Nitride semiconductors, high-frequency planar transformers and enhanced flyback topology.

The TE Series Embraces:

• A 45W (TECS/TEPS45F) and a 65W (TECS/TEPS65F) fitting into 1×2.3 (TEPS) or 1×3 (TECS) inch footprints.
• The 12V and 24V output versions are able to deliver 140% power to sustain peak loads with an outstanding efficiency of up to 93.5%.
• Two versions, either with pins (TEPS) or connectors (TECS) are available with compatible footprints to ease system upgrades.
• Standard products are delivered as an open frame though an optional dust protection case will be available.

COSEL’s R&D team developed a highly integrated power stage using Wide Band Gap (WBG) Gallium Nitride (GaN) semiconductors associated with a high frequency planar transformer.

Thanks to the COSEL’s R&D team taking the benefits of GaN performances in high frequency switching it has been possible to deliver 45 and 65W in a 1×2.3 inch (25.4 x 58.4mm Max) footprint at up to 93.5% efficiency.

Designed for flexibility, the TE series offers two interconnection versions, the TEPS with pins for PCB mounting and the TECS with crimp style JST connectors. In both cases the 45W and 65W are footprint interchangeable. Highly appreciated by systems designers, this feature simplifies layouts and provides upgrade options.

Key Features of COSEL TE Series:

• Wide Band Gap Gallium Nitride (GaN) power stage and planar magnetics
• 1×2.3 inch high power density design (TEP45F, 65F)
• 45W and 65W interoperable footprint
• High efficiency up to 93.5%
• 140% peak output current on 12V and 24V models
• Two versions with pins or connectors and dust protective case

Designed for worldwide applications, the TE series has an input voltage range of 85VAC to 264VAC single phase, and conforms to safety standards input voltage range of 100-240VAC (50/60Hz).

The TECS/TEPS45F and TECS/TEPS65F are available in three fixed output voltages, 5V, 12V and 24V with respective currents up to 45W and 65W. To accommodate the inrush current associated with DC motors, capacitor banks and similar applications, a 140% peak current option (H) will be available in Yr. 2024 for the 12V and 24V versions.

Based on the latest power electronics technologies e.g., GaN, planar-magnetics the COSEL TECS/TEPS 45W and 65W saves up to 58% board space for industrial applications.
