EQ Series cabinets provide an effective solution for applications that require distributed components such as power supplies, amplifiers, and multiple I/O modules. The EQ Series provides superior ventilation for devices such as amplifiers and field power supplies, ample room for wire or fiber-optic media between each row, and a space efficient package that allows for the consolidation of multiple system components in a single enclosure.

Equipment cabinets use a perforated blank door for enhanced ventilation, and do not support the mounting of backbox mounted dress plates. Therefore these cabinets are not appropriate for equipment that would be normally accessed by a system operator such as control equipment, annunciators, or remote microphones.

EQ cabinets share the same external dimensions as the familiar CAB-4 Series cabinets. EQ Series cabinets differ in that they do not include a separate battery row. See illustrations below for examples of EQ cabinet row spacing.
