Recently we introduced the Showtec TED Pack models. They are much improved over our previous DMX dimmer packs. Not only do they have an extra safety channel for controlling special effects, but they also use a different technology for a better dimming experience and the absence of interference to the power grid. Are you curious why? You will find out in this article.
Signal- and power-interferences are a nightmare for light designers. It is often quite a task to figure out what causes it and how to solve it. It is therefore important to eliminate any possible cause. Our new line of dimmer packs eliminates the chances of any interference and flicker. This is because the TED Pack dimmer packs are equipped with a MOSFET dimming module. This module is equipped with two dimming technologies. Previous dimmer packs only used leading edge technology, but the added trailing edge technology turns out to work better with LED and other low voltage lighting and chip-driven lighting.
By default, all TED Packs are in trailing edge mode. For dimming, it cuts of the rear edge of each half AC wave cycle instead of the front edge. This has several advantages over leading edge dimming such as smoother control and no chance of interference. This will especially have a positive and noticeable effect at low voltage lighting such as 10 W LED spots. In addition, leading edge technology can 'pollute' the power grid and can even cause speakers connected to the same power grid to buzz or hum.
Not only does the new TED Pack dimmers offer a better dimming quality and prevent interference. They also come with advanced options, such as four selectable dimming curves and three modes (DIM, SWITCH & FX). The dimming curve and mode are selectable per channel.
