Specifications A-3
Functional Specifications
Table D: NRU Functional Specifications
AC Input Frequency Tolerance 45 to 65 Hz
AC Input Voltage Tolerance ± 10%
Overload Capability
150% maximum DC bus current for 60 seconds,
200% for 10 seconds following continuous operation
Overload Duty Cycle
1 minute out of 20 minutes at rated load and
temperature
Minimum Continuous Load Requirement 33% of rated DC bus continuous current
If the total continuous DC input current of the load is less than 33% of the rate
NRU DC bus continuous current, the bus current may become discontinuous.
