1. ### LED Tape pulsating

You might need just to load the output of the 24 VDC power supply with a resistor. You can try 1 KOHM 1 Watt or parallel 4 4.7 Kohm 1/4 Watts resistors.
2. ### Upgrading 35 year old Strand AMX192 system

It could turn the existing dimming cabinet into a DMX512 controllable one.

5. ### Is it Okay for Switched-Mode Power Supplies to Make Noise?

The sound is coming from electro magnetic vibrations caused by the ON & OFF cycles caused by the PWM dimming. It is the audible harmonics of the combination of the PWM frequency and the internal frequency of the switching power supply This should not reduce the life of the Meanwel power supply...

7. ### DMX Relay Question

A Triac dimmer, which is like what the Chauvet unit has, will be able to provide 120 VAC full ON ( 99% of voltage ) or Full OFF ( still with minimum voltage created by snubbers and depending on the Load ) . There is no mechanical open gap switch to isolate completely the 120 VAC from the load...

9. ### Leviton DMS controller..? (no, really -- stop laughing!)

We could help with our MD400 retrofit lighting board. give us a call or email. http://www.digitallighting.com/protocolfolder/retrofit%20repair%20dimmer.html
10. ### Control/Dimming Interesting Problem: Convert DMX to Leviton Control

No, the boards are built as spare parts . They are exactly the same as our model# MD402, which is UL recognized, just without the Triacs. The line voltage components in the cabinet, Triacs or SCRs, chokes, breakers, wiring,...Are not modified. These retrofit boards, MD400-DMX ( DMX512) and MD400...

12. ### Control/Dimming Interesting Problem: Convert DMX to Leviton Control

We manufacture DMX512 4 channel firing boards to convert the dimmers to DMX. An inexpensive modular 4 channel per card solution to retrofit dimming cabinets. http://www.digitallighting.com/protocolfolder/retrofit%20repair%20dimmer.html
