The ADEL System FLEX28048A is a compact, high-performance 48V DIN rail power supply for industrial automation, machinery and control-panel applications. Manufactured in Italy, it delivers up to 7A and 345W from a narrow 72mm-wide enclosure.
The FLEX28048A uses a manually selectable 115 or 230VAC single-phase input and provides a regulated 48VDC output adjustable from 41 to 55VDC. Its flexible-power design supplies up to 7A at lower ambient temperatures, with continuous output capability across a wide industrial temperature range.
High efficiency, strong overload handling, three selectable protection modes and Easy Parallel operation make the FLEX28048A suitable for communications equipment, industrial computers, drives, actuators and other systems requiring a reliable high-voltage DC supply.
A compact industrial power supply delivering up to 345W with flexible output power, selectable protection modes and strong overload capability.
The FLEX28048A converts a single-phase AC input into a stable 48VDC supply for professional industrial equipment. Its compact design, natural-convection cooling and high power density make it well suited to control cabinets where available DIN rail space is limited.
This 48V DIN rail power supply is suitable for applications including:
The FLEX28048A provides output power according to ambient temperature, delivering 7A at 48VDC below 40°C, 6A below 50°C and 5A below 60°C. This corresponds to a continuous output range from 240W to 336W, with up to approximately 345W available through output-voltage adjustment.
A power-boost function can provide up to 150% of the 60°C rated current for at least three minutes, helping the supply support high start-up currents and temporary load peaks.
The FLEX28048A provides three selectable responses to overload and short-circuit conditions: hiccup mode, continuous-output mode and manual reset. This allows the protection behaviour to be matched to the connected load.
The supply can start capacitive loads up to 50,000µF, making it suitable for electronic equipment with large input capacitors and demanding start-up characteristics.
Easy Parallel functionality allows compatible units to be connected where additional current capacity or system redundancy is required.
The FLEX28048A is manufactured in Italy by ADEL System for professional industrial control, machinery and communications applications.
