SSD-DCDth / Solid-State Decoupler device is used to isolate or clamp a DC voltage as well as ground AC voltage and ground AC voltage.
So that a safe working environment and required potentials can be maintained.
- over voltage protection of insulating joints,
- DC isolation
- AC grounding of Cathodically Protected structures.
Options for each type
Cathtect’s SSD-DCDth product line consists of 5 standard sizes namely 1,2kA | 2kA | 3,7kA | 5kA | 9,5kA – Therefore each type has 6 different options of DC Threshold to choose from, but they are all @60Hz
Different DC Thresholds to choose from:
- -2V to +2V
- -5,6V to +2V
- 9,2V to 2V
- 12,8V to +2V
- 16,4V to +2V
- -20V to +2V
Solid-State Decoupler SSD-DCDth 3,7kA @ 30cycles 50Hz
- 3.7kA, +2 to -20V DC Threshold, 30V 45A AC Mitigation Rating, 50/60Hz Frequency
- 1.2kA, +2 to -20V DC Threshold, 30V 45A AC Mitigation Rating, 50/60Hz Frequency
