Cosel takes industrial power supply range to 800kHz with GaN
Cosel is adopting GaN transistors and high frequency planar magnetics for a new generation of higher efficiency, smaller industrial power supplies
The Cosel TE industrial power supply series uses a GaN-based flyback topology for 45W (TECS/TEPS45F) and 65W (TECS/TEPS65F) industrial power supplies in 1×2.3in (TEPS) or 1x3in (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.
The GaN transistors with a high frequency planar transformer provide efficiencies up to 93.5% at 800kHz with 140% peak output current on 12V and 24V models with the 25.4 x 58.4mm footprint.
- Cosel moves to SiC for fanless 3-phase 3.5kW power
- 3kW low profile AC-DC power supply for industrial
- 800W supply provides 300% peak power
The TE series offers two interconnection versions for flexibility with TEPS with pins for PCB mounting and the TECS with crimp style JST connectors. In both cases the 45W and 65W are footprint interchangeable to simplify layouts and provides upgrade options.
Cosel also took into consideration the requirement to minimize the size of the power supply, and adopted a vertical assembly technique that combined with a higher switching frequency of up to 800KHz saves about 58% board space.
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). It has 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.
The units are designed to operate from -10 to +70 degrees Centigrade, and they can be mounted in any orientation, although depending on the ambient temperature and environment a derating may apply. The units have a 3,000VAC input to output isolation voltage and a leakage current of 0.25mA max complying with the IEC62368 specification.
Cosel’s TECS/TEPS45-65F units are ideal for Class II equipment and are able to achieve a low noise performance without requiring any ground connection. The GaN flyback design provides a no load power consumption as low as 200mW.
The TECS/TEPS measures (W x H x D): TECS45F: 25.4 x 23.5 x 76.2 mm (1.00 x 0.93 x 3.00 inches) ; TEPS45F: 25.4 x 24.0 x 58.5 mm (1.00 x 0.94 x 2.30 inches) ; TECS65F: 25.4 x 27.0 x 76.2 mm (1.00 x 1.06 x 3.00 inches) and the TEPS65F: 25.4 x 27.5 x 58.5 mm (1.00 x 1.08 x 2.30 inches). For applications requiring dust protection, a version with plastic case will be available, option (N), in Yr. 2024.
The TECS/TEPS45-65F meet the safety agency approval UL62368-1 and c-UL (equivalent to CAN/CSA-C22.2 No.62368-1), EN62368-1. The products also comply with the Japanese Electrical Appliance and Material Safety Act DEN-AN
