1500 Watt Axial Leaded Transient Voltage Suppressors
The 1.5KE Series is designed specifically to protect sensitive
electronics equipment from voltage transients induced by
lightning and other transient voltage events. These devices are
ideal for the protection of I/O interfaces, Vcc bus and other
vulnerable circuits used in telecom, computer, industrial and
consumer electronic applications.
