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.
