By Nick Flaherty

The AXA 25W series converters are encapsulated in a compact metal 1.0 x 1.0 x 0.4 inch (25.4 x 25.4 x 10.16 mm) industry-standard package with isolated baseplate and offerup to 90 percent efficiency. The converters cover a wide 4:1 input voltage range of 24 V or 48 V (9 – 36 Vdc and 18 – 75 Vdc) with single- or dual-output variants. The proven rugged design and encapsulation of this converter family enables operation in harsh environments.

The series consists of single 3.3 V, 5 V, 12 V and 15 V output models together with +12/-12 and +15/-15 V dual output models. These dc-dc modules can operate from -40 ºC to +85 ºC and offer additional features such as overload protection, remote on/off control, input-to-output isolation voltage of 1500 Vdc, and –  on single output models – the output voltage can be trimmed by +/- 10 percent of the nominal output. All models are approved to CSA/NTRL/IEC/EN 60950-1 for IT equipment.
