  • Survives 300 VAC surge and 5 G vibration with short-circuit overload over-voltage protection

Industrial 48 V DC supply

This 75 W enclosed unit delivers a steady 48 V at 1.6 A for automation cabinets, test equipment, 3D printers or LED lighting. It accepts a universal 85–264 VAC input and operates reliably up to 70 °C ambient temperature. No-load consumption stays below 0.3 W, and a built-in LED shows power-on status.

1U low-profile mounting

The 30 mm high chassis fits tight DIN-rail or panel spaces without forced-air cooling, relying on free-air convection instead. Short-circuit, overload and over-voltage protection guard connected loads, while the 300 VAC surge tolerance for five seconds absorbs mains transients. Vibration resistance to 5 G suits mobile or machinery-mounted installs.

Convection-cooled thermal design

Silent operation is assured because no fan is fitted; heat dissipates through the metal enclosure during normal loads. Efficiency remains high across the output range, supporting long-life continuous duty at up to 5000 m altitude. Certified to EN 62368-1, EN 60335-1 and EN 61558-1/-2-16 for household-appliance safety.

أسئلة حول هذا المنتج

At what ambient temperature does the LRS-75-48 begin to derate?

The supply is rated for continuous operation up to 70 °C; above that temperature output power must be reduced.

How much acoustic noise does the fanless design produce during 24-hour operation?

Cooling is by free air convection only, so the unit runs completely silently.

Which mains cable does the enclosed terminal block require?

A standard three-core mains lead with stripped ends is needed to connect to the screw terminals.
