 4502 |
 4520A |
| The 4500 series is a power amplifier which has frequency range of from DC to 20kHz . 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. |
| Model | Description |
| 4502 | DC to 20kHz ¡Ó200V 2.1Arms |
| 4505 | DC to 20kHz ¡Ó200V 4.2Arms |
