Tripp Lite DB25 White surge protector

Network Surge Suppressor - Essential protection for data and communication lines Tripp Lite's DB25 offers dataline surge suppression for many RS232 DB25 serial ports of data terminal and data communications equipment, including PCs, printers, modems and more. Protects pins 1-8, 20 and D shell chassis for protection of specific DB25 applications. User configurable for use with male or female captive DB25 port. Convenient DB25 input and output connects directly to the protected port, obtaining a ground outlet from the computer chassis. Surge suppression is handled with balanced arrays of high-speed avalanche diodes that divert excess energies created by electrostatic discharges, faulty wiring or lightning away from network interface connections. Tripp Lite network surge suppressors reduce blown interface connections, garbled transmissions, system lock-ups and hard equipment failure by safely shunting dataline surges to ground.

SUPPRESSION: Reversible DB25 m/f jacks, protects pins 1-8, 20 and chassis, 18V clamping.
