AC/DC Power Supplies
Cosel TECS10F Series Open Frame AC/DC Power Supply
When board space is the constraint, the Cosel TECS10F Series fits where larger supplies can't. It's a compact open-frame AC/DC power supply in a 1" x 2.3" footprint just 1.1mm-PCB thin, delivering up to 10W from a universal 85-264VAC input — one part valid on any mains worldwide.

Read MoreWhen board space is the constraint, the Cosel TECS10F Series fits where larger supplies can't. It's a compact open-frame AC/DC power supply in a 1" x 2.3" footprint just 1.1mm-PCB thin, delivering up to 10W 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, 15V 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.
