It accepts a wide universal input range of 88 VAC to 264 VAC at 47 to 63 Hz, making it suitable for use with standard single-phase AC mains across a broad range of installations. The unit uses free-air convection cooling with no internal fan, and is housed in a compact silver metal enclosure measuring approximately 6.26 x 3.82 x 1.50 inches. Agency approvals listed by Jameco include UL, CUL, TUV, CB, CE, EN, and EAC.
Key Features and Benefits
Wide universal AC input range (88 VAC to 264 VAC) - Supports use with a broad range of single-phase AC mains without manual voltage switching, for compatible installations.
Free-air convection cooling - no internal fan - Supports quieter operation and helps reduce mechanical wear points; requires adequate clearance around the unit for airflow per the datasheet.
Built-in overload protection (110% to 180% of rated output) - Helps protect the supply and connected equipment when load current exceeds rated limits, within the manufacturer's stated parameters.
Over-voltage protection (115% to 135% of rated output voltage, hiccup mode, auto-recovery) - Helps limit output voltage excursions; supply recovers automatically after an over-voltage event, per the manufacturer's stated behavior.
LED power-on indicator - Provides a quick visual confirmation that the supply is energized during installation and operation.
105°C long-life electrolytic capacitors - Supports extended service life in applications where the supply operates at or near its rated temperature range.
Low no-load power consumption (<0.5 W) - Helps reduce standby energy draw when the supply is energized but the load is disconnected.
Surge withstand up to 300 VAC for 5 seconds - Supports resilience against brief AC line surges within the manufacturer's stated limits.
Vibration withstand rated to 5G - Supports use in environments with moderate mechanical vibration, when installed according to the datasheet.
Screw terminal block output connector - Simplifies field wiring and supports secure, tool-terminated connections to load equipment.
Agency approvals listed by Jameco: UL, CUL, TUV, CB, CE, EN, EAC - Supports use in applications where third-party safety certification is required; verify applicable standards against the datasheet for your specific application.

Customer Questions
Does the RS-100-24 require a cooling fan or forced airflow?
No. The RS-100-24 uses free-air convection cooling and does not include an internal fan. Adequate clearance around the enclosure should be maintained as specified in the datasheet to support proper thermal performance.
What input voltage does the RS-100-24 accept?
The RS-100-24 accepts a wide universal AC input range of 88 VAC to 264 VAC at 47 to 63 Hz. No manual voltage selection switch is required.
What protections are built into this power supply?
The RS-100-24 includes overload protection (110% to 180% of rated output current) and over-voltage protection (115% to 135% of rated output voltage) with hiccup mode and auto-recovery, per the manufacturer's stated specifications.
Can this supply operate continuously at full load?
The RS-100-24 is rated for continuous operation within its specified temperature range of -25°C to +70°C. Consult the datasheet for derating guidelines at elevated ambient temperatures.
What certifications does the RS-100-24 carry?
Agency approvals listed by Jameco for this product include UL, CUL, TUV, CB, CE, EN, and EAC. Refer to the datasheet and MEAN WELL compliance documentation for specific standards and applicable markets.
Customer Concerns
I need to confirm the supply will fit in my enclosure before ordering.
The RS-100-24 measures approximately 6.26 inches long x 3.82 inches wide x 1.50 inches tall. A 3D outline file (STEP format) is available on the product page to support mechanical verification before installation.
I am not sure whether this supply can handle my load without overheating.
The RS-100-24 is rated for up to 4.5 A at 24 VDC (108 W rated, 110 W maximum). It uses convection cooling with no fan, so adequate clearance around the unit is important. Review the datasheet derating curve for operation above 50°C ambient to confirm suitability for your load and installation environment.
I want to verify the safety certifications are appropriate for my application.
Agency approvals listed by Jameco include UL, CUL, TUV, CB, CE, EN, and EAC. UL60950-1 compliance has been noted across multiple sources. Verify the specific applicable standards against the MEAN WELL datasheet and compliance documentation linked on the product page to confirm suitability for your end-use application.
