Modular surge protector RayDat SRH-2L

DIN raillow-voltage

IEC/EN Category: D1/C1/C2/C3 Mode of Protection: Longitudinal, Transverse Voltages: 5, 12, 24, 30 V DC Frequency Range: 30 MHz Surge Discharge Ratings: In: 10 kA, Imax: 20 kA, Iimp: 2.5 kA Series Load Current: 1 A Enclosure: DIN 43880 2/3 TE, DIN Rail Mount Terminals: Stranded to 4 mm2 Housing: Modular Design Compliance: IEC/EN 61643-21 The RayDat SRH-2L Series provides the same level of protection and technical performance as the SLH-2L Series, but also provides a visual LED indication. If the unit fails, the LED is lighted. Note: the device must be properly connected to RayDat PSU-14 unit. These barriers provide both coarse and fine protection stages and offer longitudinal and transverse 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 implemented using fast bidirectional silicon avalanche diodes. Special design techniques have been employed in the design of the fine protection stage to avoid capacitive line loading and thereby ensure a low insertion loss and wide operating frequency range. Series line impedance is used to ensure energy co-ordination between the coarse and fine protection stages irrespective of the magnitude of the incident surge. When power frequency contact occurs between power and communication lines, the hazard of electric shock and fire is increased. To prevent such risk, a thermo-clip is included in the primary protection stage of this device to divert the power frequency current to ground.
