1. Due to continuous improvements all specifications are subject to change.
2. At minimal connection cable inductance and sufficient LD stage voltage.
3. Calculated as bias current + averaged pulse current. At headroom voltage 2 V (optimized for 100 A pulse current).
4. Other values/types available on demand.
5. Factory-configured on order specification.
6. De-rate LD RMS current at higher temperature.
