What the actual PWM rate of LED Dimmer?
I’m thinking about getting an Absolute 16’ strip and might decide to also buy your FilmGrade PWM dimmer to put in between the power supply and the strip. What is the PWM rate (Hz) on this dimmer? Specs indicate it was tested on frame rates up to 240fps but I’m wondering what the actual rate is. The specs for the other DMX dimmer indicate 30kHz so I’m hoping the FilmGrade dimmer is at least 25kHz as recommended in your support docs about dimming/flicker.
We can confirm that the PWM rate of the FilmGrade™ Flicker-Free LED Dimmer is 25 kHz.
I see that as opposed to the FilmGrade strips which are available in 12V or 24V options, the Absolute strips are only 12V. Since I will likely be using the full 16 ft (cut into several small strips connected together) with a single power supply, I thought 24V would be a little better (less voltage drop, higher efficiency). However, the Absolute strips are only 12V so I'm wondering if these will be ok or if I should perhaps consider using Absolute modules instead. It seems the modules can be daisy-chained and are 24V and can be dimmed using the same FilmGrade LED dimmer as the strips. Any suggestions?
You are correct that unfortunately, the ABSOLUTE SERIES LED strip lights are available in 12 volts only. When used as a continuous, 16.4 ft reel without being cut into shorter sections, we have not observed any voltage drop issues.
We have seen some situations, however, where voltage drop becomes an issue when many shorter sections are joined together using connectors and wires, as these act as bottlenecks for electrical current and can cause drops in brightness.
The ABSOLUTE SERIES LED modules may be a more reliable option since as you mention, they operate at 24 volts and will therefore exhibit lower voltage drop issues. The modules are also fully compatible with the flicker-free dimmer, although some extra components such as PN 7095 and connection wires would be required for assembly.
