When board space is the constraint, the Cosel TECS65F Series fits where larger supplies can't. It's a compact open-frame AC/DC power supply in a 1" x 3" footprint just 1.1mm-PCB thin, delivering up to 65W from a universal 85-264VAC input — one part valid on any mains worldwide.

Despite the size, protection is built in: inrush current limiting, overcurrent protection and overvoltage protection are all on board, and the series is Class II rated, so no protective-earth connection is required. A harmonic attenuator brings IEC61000-3-2 compliance, and outputs of 5V, 12V, and 24V cover the common rails.

H-option models add a higher peak-current rating for 12V and 24V outputs — useful for short motor or capacitive surges — while the -Y option adds an output-adjust potentiometer (±10%) and -N adds a protective cover. Manufactured with SMD technology and backed by a 5-year warranty.

FAQs
The TECS65F is a 65W open-frame AC/DC power supply — the highest-power model in the Cosel TECS F-series — designed for PCB/bare-board integration in OEM equipment.
Contact Powerbox for the output voltage options in the TECS65F range.
Universal AC input (85–264Vac).
The TECS65F (65W) delivers 44% more output power than the TECS45F (45W), in the same open-frame design. Specify the TECS65F when the OEM equipment's power budget exceeds 45W.
Safety: UL62368-1, C-UL (equivalent to CAN/CSA-C22.2 No. 62368-1), EN62368-1. EMC: built-in harmonic attenuator to IEC61000-3-2. Class II construction with no FG connection required. Options include low leakage current variant (suffix E2, for medical-environment proximity), output peak current boost on 12V and 24V models (suffix H), and a cover option (suffix N) for applications requiring mechanical protection. RoHS compliant. 5-year Cosel manufacturer's warranty.
OEM industrial instruments, embedded systems, medical-adjacent equipment, and any product requiring a compact, certified, open-frame AC/DC supply at 65W.
