"PLC" Protector (series)
AC power and data line protection in one convenient box. Among other applications, the PLC Protector can be applied to PLC's, robotics, CAD/CAM, alarm systems, scanners, controllers, medical equipment and virtually all microprocessor-based "critical" equipment.

TTF/ILF Isolating Line Filter (parallel)
The TTF/ILF combines a low-pass series filter with a toroidal isolation transformer. The TTF/ILF provides for total protection against all power aberrations and eliminates any troublesome constant voltages which may exist between neutral and ground in some electrical configurations.

"ESE" Electrical Service Entrance (parallel)
The Always n™ ESE TVSS filter is designed to protect, at the power panel, against externally and internally produced power aberrations, massive impulses, lightning induced effects and interference associated with low frequency harmonics and situations caused by accidents and/or failures in the electrical utility system.
