NPG series nanosecond pulse generators are designed for laboratory or industrial applications. They are suitable for 24/7 maintenance free operation. NPG nanosecond pulse generators have user friendly and simple interface which excludes operation error and possible damage of the nanosecond pulse generator or other equipment. They can work with any type of the load including short or open load. Nanosecond pulse generators have overtemperature and over frequency protection. The last is useful for external triggering operation mode. In case of overheating the generator will return to normal operation automatically after few minutes of idle operation when the circuit components temperature reduces below the safe level. Breakdown in the load does not lead to the damage of the nanosecond pulse generator because of reliable protection system.
