Features: Wide range : DC to 20 kHz Rated output power: 250VA Maximum output power with respect to products: 313VA Rated output: DC mode ± 1.9A Current: AC mode(RMS): 2.1Arms Peak current: 2.5 X rated value (RMS) Rated output voltage: 120Vrms (± 170V) sinewave Maximum output voltage: 141Vrms (± 200V) sinewave Four modes of DC (CC/CV) and AC (CV/CC) Output voltage can be boosted up by serial connection The NF Corporation 4502 is a power amplifier which has frequency range of from DC to 20 kHz . It is available for a constant current output and a remote sensing. It is appropriate for power environments testing by none-sinusoidal waveform like instantaneous break of half wave. In addition, by combining boosters with the 2kVA amplifier, power output of up to 10kVA (in 2kVA/booster) is possible.
