The Zero 88 Betapack and Betapack Plus series of dimmer packs are 4U high-professional, six-channel power controllers capable of driving up to 10 amps of lighting loads per channel. These loads may be resistive or inductive and include tungsten, transformer driven low voltage (eg. pinspots), and quartz halogen. Some highly inductive loads, such as neon, will require a ballast load of 100 watts.

Betapack 1 was launched in 1990.
