RC300 power options for vehicle LED screens
The Sysolution RC300 series is designed for vehicle display applications using a DC power source. The linked specification lists low-temperature starting, full-load aging tests and a green power-status indicator. Its output options have different voltage and power ratings, so selection depends on the LED modules and the exact model suffix.
The input range is 9–36 VDC, with 12 V and 24 V listed as typical values. Keep the model-specific output ratings together when comparing options. The PDF contains conflicting cooling descriptions—built-in fan cooling in the features and natural cooling in the working-condition table—so confirm the physical unit and provide the required heat dissipation.

Frequently asked questions
Is every RC300 version rated at 300 W?
No. The RC300 series table lists RC300D4.2 at 250 W, RC300D4.5 at 270 W and RC300D5 at 300 W. Confirm the suffix and required LED module voltage before ordering.
Can the RC300 use a 12 V or 24 V vehicle supply?
The specification gives a 9–36 VDC input range and lists 12 V and 24 V as typical values. Check the actual vehicle supply, wiring and input conditions against the selected unit’s requirements.
Which output voltage should I choose?
Match the module’s required voltage to the exact version: RC300D4.2 is 4.2 V, RC300D4.5 is 4.5 V and RC300D5 is 5.0 V. These are different model options; do not assume one unit provides all three output voltages.
Does the RC300 have a cooling fan?
The feature list and original product text specify a built-in DC fan, but the PDF operating-condition table says natural cooling. Confirm the cooling arrangement of the supplied unit. The installation notes call for mounting to the system’s metal enclosure and recommend below 80% load when heat dissipation is poor.
What should I check when mounting the RC300?
The specification calls for M3 screws with less than 3.5 mm penetration into the power supply. It also recommends direct mounting to the system’s metal enclosure for heat dissipation. Check the exact version, polarity and output voltage before connecting the LED load.
