| High voltage reed relays |
"DOLAM" S.A. has produced:
|
High voltage reed relays
|
| High voltage reed relays are assigned to switch and separation high voltage circuits from 5kV to 19kV. There are produced 3 type of relays: - type K-55xH - leads of reed switches are performed by elastic HV cables, leads of coil are adapted to PCB mounting,
- type K-56xH and R56x - all leads of relay are adapted to PCB mounting.
|
Basic parameters of relays type K-55xH, K-56xH and R-56x see below. More information are in data sheet in section Documentation » Data sheets. |
