DC Surge Protection

Single and 3-stage heavy duty suppression

Industrial Ethernet Surge Suppressor

Model EIRSP1 is compatible with 10/100BaseT equipment and fully 802.11af(Power over Ethernet) compliant. Protection on all eight RJ-45 lines; works with Mode A and Mode B PoE systems.

Single Stage Surge Protectors

Each unit offers a high degree of protection with Transient Voltage Suppressors (TVS) for each protected line. Model 485FPP is for RS-422 and RS-485 circuits. It has surge suppression and fast-acting 125 mA PCB fuses to protect against transient voltages that are too long or too large for normal suppression. 600W surge suppression and simple in-line installation

DIN Rail Dataline Surge Suppresso

Model HESP4DR protects against lightning strikes, power surges, and other voltage disturbances common to DIN rail components. Five RS-422/485 signals on terminal blocks are supported with a clamping voltage of 6.8 Volts. HESP4DR has three stages of protection:
1) gas discharge tube,
2) series resistor
3) Transient Voltage Suppressor (TVS).

Heavy duty, 3-Stage Surge Protectors

Meet IEEE 1000-4-5: 1995 and IEEE C62.41-1991 recognized standards for top quality surge protectors. Heavy duty 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 data line. Protected signal ground connection and dedicated chassis ground lug.
