The MEAN WELL SE-1000-48 is an enclosed, switch-selectable switching mode power supply (SMPS) that delivers 48 VDC at up to 20.8 A for a total output power of 998.4 W. It accepts a wide-range AC input of 90 VAC to 264 VAC (switch selectable between 115 V and 230 V ranges) at 47 Hz to 63 Hz, making it suitable for use in both North American and international AC mains environments. The unit features a silver enclosed chassis measuring 10.9 x 5 x 2.5 inches and carries agency approvals listed by MEAN WELL as UL, CUL, EAC, and BSMI.
Key Features and Benefits
Switch-selectable input voltage (90-132 VAC or 180-264 VAC) - Supports deployment in both 115 V and 230 V AC mains environments without rewiring.
998.4 W output power at 48 VDC / 20.8 A - Provides substantial continuous power capacity for high-demand 48 V loads within the manufacturer's stated ratings.
89% typical efficiency - Helps reduce heat generation and energy consumption compared to lower-efficiency designs.
Built-in protections: short circuit, overload, over voltage, and over temperature - Helps safeguard connected equipment and the supply itself under fault conditions, within the manufacturer's stated limits.
Built-in remote sense function - Helps compensate for voltage drop across output wiring, supporting more accurate voltage delivery at the load.
DC OK signal output and built-in remote On/Off control - Supports system integration by allowing external monitoring of output status and remote enable/disable of the supply.
Lug terminal female output connector - Supports secure, high-current wiring connections suitable for the supply's rated output.
3000 V minimum isolation voltage (input to output) - Provides a high isolation barrier between AC input and DC output, consistent with enclosed SMPS design requirements.
Enclosed silver chassis, 10.9 x 5 x 2.5 inches - Compact enclosed form factor supports panel or chassis mounting in equipment enclosures.
Agency approvals listed by MEAN WELL: UL, CUL, EAC, BSMI - Supports use in applications where recognized agency approvals are required.

Customer Concerns
I need to verify the supply will fit in my existing enclosure before ordering.
The SE-1000-48 measures 10.9 inches long by 5 inches wide by 2.5 inches tall. Review the datasheet for exact mounting hole locations and clearance requirements before installation.
I am unsure whether this supply will work on my local mains voltage.
The SE-1000-48 uses a switch-selectable input that covers both 115 V range (90-132 VAC) and 230 V range (180-264 VAC). Verify the switch is set to the correct position for your mains voltage before powering on, as described in the datasheet.
Will this supply handle my full load continuously without overheating?
The SE-1000-48 is rated for operation from -20 to +60 °C. Output derating may apply at elevated ambient temperatures. Consult the datasheet for derating curves and confirm adequate airflow around the unit when installed in an enclosure.
