SPD for power supply ES series for grounding
Showden Co., Ltd.
About This Product
■Small SPD for grounding
The ES series is a small SPD for use between grounds that can equalize the potential of different grounds. Mainly connect the shielded wire in a place where it is not directly grounded or between SG (signal ground) and FG (frame ground) to suppress overvoltage.
■Possible to equalize the potential of different grounds
Connect and integrate grounding to equalize the potential of equipment grounding. Grounding that cannot be integrated due to its functionality (power system B/C grounding, computer grounding, grounding for other communication equipment, etc.) can be integrated with different types of grounding via SPD. The ground-to-ground SPD is always in an isolated state and can switch and integrate the ground when high voltage is applied between the grounds during a lightning strike.
■Features
No alarm contact
