Current Limiter - NF DP Series Instruction Manual

10. Specifications

10.13 Current Limiter

This controls the output voltage for the output current to be within the limiter setting value when
the peak value or RMS exceeds it. The output can be configured to be turned off when the limited
state continues over the specified time.
In the polyphase model, polyphase system, and polyphase output of the Multi-phase model, the
settings are made for the phase current and common to all the phases.

*55: If you increased or decreased the number of units by the power unit energization setting, the
factory default setting corresponding to the capacity is used. (Example: In the case that only 3
units operate in 6 kVA model, the factory default setting of 4.5 kVA model is used.)

Select whether to recover automatically (continuous) or turn the output off
when the limited state continues over the specified time (1 s to 10 s,
resolution 1 s).
Factory default setting is output OFF when the limit state continues for 10 s.
