Isolation terminology
1. Working or Operating Voltage: Continuous
voltage across isolation (560Vpk or 890Vpk)
2. Isolation or Transient Voltage (Vrms):
Transient voltage across isolation (4kVpk or
6kVpk)
3. Basic Isolation: 560Vpk continuous, 4kVpk
transient voltage
4. Reinforced Isolation: 890Vpk continuous,
6kVpk transient,10kV surge voltage
