Modular surge protector RayDat SLH-2 / SLH-4

3-polegas discharge tubeDIN rail

RayDat SLH-2 These efficient overvoltage barriers contain both coarse and fine protection stages and provide longitudinal and transverse surge protection. The initial protection stage comprises a three-pole gas discharge tube and is designed to divert the primary surge energy. The subsequent fine protection stage is carried out using fast bidirectional silicon avalanche diodes. Care is taken in the design of this fine protection stage to avoid capacitive line loading and thereby ensuring a low insertion loss and wide operating frequency range. Series line impedances ensure energy coordination between the coarse and fine protection stages at all levels of the incident surge. To protect against the hazards of electric shock and fire which often results when power frequency contact occurs between power and communication lines, often called mains incursion, a thermo-clip is included on the primary protection stage to divert the power frequency current to ground. The plug-in module/base design facilitates the replacement of a failed module without the need to remove system wiring. If the module is unplugged out of the base, the connection lines remain enabled. RayDat SLH-4 Like the RayDat SLH-2 Series, the SLH-4 provides the same level of protection to two independent circuit pairs. A number of protection voltages are available to ensure the user is able to select the closest clamping voltage to the normal signal operation of the equipment being protected.
