An industrial printing OEM client approached Relec via our contact form, looking for a high-efficiency AC-DC converter with a strict size constraint.

The brief was clear:

<65W continuous output
12V and 24V options
Must withstand wide temp ranges
Low noise (no ground connection required)
Class II safety compliance
Ultra-compact footprint

Why the tight squeeze? The unit was being integrated into a mobile enclosure with barely enough space for airflow, let alone a bulky PSU.

We recommended the Cosel TECS/TEPS Series, specifically the 65W version with 24V output — TECS65F-24.

Key benefits we outlined:
Fits in just 1 x 2.3 inches (TEPS) or 1 x 3 inches (TECS)
Available with pins (TEPS) or connectors (TECS) — ideal for both layout styles
5% efficiency at rated load
140% peak current support – perfect for the inrush of the printer’s servo drive
Can operate from -10°C to +70°C
Only 200mW consumption at no load — helpful for energy usage compliance

To future-proof their design, we also recommended the -N case option for dust protection and discussed mounting orientation considerations for thermal optimisation.

HOVER

The client successfully integrated the TECS unit into their updated printer, hitting their footprint and power targets without redesigning their board layout.

Thanks to the interchangeable footprint between the 45W and 65W models, they now have flexibility across our entire range of printer using the same PCB — simplifying production and stock holding.

Less heat. Less space. More headroom for peak loads.

The Cosel TECS/TEPS Series delivers advanced GaN efficiency in a surprisingly small space.

Available in 10W, 20W, 45W and 65W formats — with pins or connectors to suit your build.
