• Heavy Duty Surge Protectors
Heavy duty data line surge protectors meet tough IEEE specifications
IEEE 1000-4-5: 1995 and IEEE C62.41-1991 are the recognized standards for top quality, heavy duty surge protectors.
B&B Electronics’ RS-232, RS-422, RS-485 data line surge protector units meet these specifications with three stage protection for maximum safety: a gas discharge tube feeds to a series resistor and a TVS (Transient Voltage Suppressor) for each supported line.
