Max. common mode voltage Primary connection
The following two conditions must be continuously – 2 M5 studs
and simultaneously respected:
1) U HT+ + U HT- ≤ 10 kV peak Standard secondary connection
and – 3 M5 studs
2) | U HT+ - U HT- | ≤ U PMAX
Options
– Primary connection: 2 separated High Voltage cables.
General data – Secondary connection: shielded cable (2 m), M5 inserts,
Lemo connector.
– Coated electronic circuit.
– Nominal secondary current I SN :
– Plastic case and insulating resin are self-extinguishing.
I SN (for U PN)= 20 mA or I SN (for U PN) = 80 mA.
– Direction of the current: A positive primary differential voltage
(U HT+ - U HT- > 0) results in a positive secondary output current
from terminal M.
