The MEAN WELL RD-50A is a 54W enclosed switching power supply from the RD Series that delivers two independent DC output channels - 5V at 6A and 12V at 2A - from a universal AC input ranging from 88 to 264 VAC at 47 to 63 Hz, making it compatible with mains voltages found in most regions without manual switching. The compact enclosed design measures 3.9 x 3.8 x 1.4 inches, uses free air convection cooling, and operates across a wide temperature range of -25°C to 70°C. Built-in protections for short circuit, overload, and over voltage help safeguard connected equipment within the manufacturer's stated limits, and every unit undergoes a 100% full load burn-in test before shipment. Agency approvals listed by the manufacturer include UL, CUL, TUV, CB, CE, EN, and EAC.
Key Features and Benefits
Dual DC output channels: 5V at 6A (Channel 1) and 12V at 2A (Channel 2) - Supports equipment that requires two separate supply voltages from a single compact unit.
Universal AC input range: 88 to 264 VAC at 47 to 63 Hz with automatic switching - Supports operation on mains voltages found in most countries without manual voltage selection.
Built-in short circuit, overload, and over voltage protections - Helps safeguard connected equipment and the power supply itself within the manufacturer's stated limits.
Free air convection cooling - no internal fan required - Supports quieter operation and reduces mechanical wear associated with fan-cooled designs.
Wide operating temperature range: -25°C to 70°C - Supports deployment in environments with elevated ambient temperatures, up to the manufacturer's stated maximum.
Withstands 300 VAC surge input for 5 seconds - Helps the unit tolerate brief input voltage surges within the manufacturer's stated test conditions.
Passes 5G vibration test - Supports use in applications subject to mechanical vibration, within the manufacturer's tested limits.
105°C rated long-life electrolytic capacitors - Supports extended service life under elevated operating temperatures.
100% full load burn-in test performed on every unit - Supports confidence in out-of-box reliability before installation.
LED power-on indicator - Provides a quick visual confirmation that the unit is energized during installation and operation.
Screw terminal block output connectors - Supports secure, tool-assisted wiring connections for reliable field installation.
Agency approvals listed by MEAN WELL: UL, CUL, TUV, CB, CE, EN, EAC - Supports use in applications and regions where third-party safety certification is required.
3-year manufacturer warranty - Provides documented coverage for the product over an extended service period.

Customer Questions
Does the RD-50A require a fan for cooling?
No. The RD-50A uses free air convection cooling and does not include an internal fan. Adequate clearance around the unit should be maintained to allow airflow, as described in the manufacturer's datasheet.
What input voltages does the RD-50A accept?
The RD-50A accepts a universal AC input range of 88 to 264 VAC at 47 to 63 Hz with automatic switching. No manual voltage selection is required.
What output voltages and currents does the RD-50A provide?
Channel 1 provides 5 VDC at up to 6A. Channel 2 provides 12 VDC at up to 2A. Total rated output power is 54W.
Is the RD-50A suitable for continuous operation?
The RD-50A is rated for operation up to 70°C and has undergone a 100% full load burn-in test. Refer to the manufacturer's datasheet for derating guidelines at elevated ambient temperatures.
What certifications does the RD-50A carry?
Agency approvals listed by MEAN WELL include UL, CUL, TUV, CB, CE, EN, and EAC. Compliance documentation is available on the Jameco product page.
Customer Concerns
I need to confirm the unit will fit in my enclosure before ordering.
The RD-50A measures 3.9 inches long by 3.8 inches wide by 1.4 inches tall and weighs approximately 0.9 lb. Verify these dimensions against your enclosure drawings and allow adequate clearance for free air convection cooling as specified in the datasheet.
I am not sure whether the total 54W rating means I can draw full current on both channels simultaneously.
The total rated output power is 54W across both channels. The maximum load on each channel is 5V at 6A (30W) and 12V at 2A (24W). Consult the manufacturer's datasheet for combined load derating curves and any cross-loading restrictions before finalizing your design.
I am concerned about whether this supply is appropriate for my application's compliance requirements.
Agency approvals listed by MEAN WELL include UL, CUL, TUV, CB, CE, EN, and EAC. Compliance documents including TSCA, REACH, Conflict-Free, and RoHS certificates are available on the Jameco product page. Confirm that the specific standards required by your application are covered by reviewing the manufacturer's compliance documentation.
