Buyer questions
Is the output regulated to a constant 24V?
No. The listed output is 22.80V at full load and 28.4V open circuit. The LED load must accept the actual voltage variation and waveform.
What load range is listed for non-dimming operation?
A compatible 20–40W LED load. Input is 120V AC, ±5%, at 50/60Hz; maximum total output is 40W.
Can I add an output-side PWM controller or RF receiver?
Do not add either without a verified compatible combination. Forward-phase / MLV dimming also requires a matched load and dimmer.
