* 1. The peak value of the sum of the DC current and AC current is limited by the DC current’s settable range. * 2. At an ambient temperature between 18 °C and 28 °C. * 3. At an ambient temperature between 18 °C and 28 °C, with a 100 Hz sine wave, 35 μs response, and shorted output. *4. A frequency where the amplitude ratio of the output current to the external signal input voltage is -3 dB (when the reference frequency is 100 Hz, the response is 35 μs, and a rated load is connected). The frequency response changes according to the load impedance. When the load impedance increases, the frequency response decreases. *5. The rise or fall time (at rated load; excluding when output is turned on and off). The rise and fall times change according to the load impedance. *6. Rise time:The time it takes for the output current to rise from 10 % to 90 % of the rating when the output current is changed from 0 A to the rated current. Fall time:The time it takes for the output current to fall from 90 % to 10 % of the rating when the output current is changed from the rated current to 0 A. * 7. The measurement frequency bandwidth is 10 Hz to 1 MHz (when the output voltage is in the range of 10 % to 100 % of the rated output voltage). * 8. The change in the output current in response to a change in the output voltage from 10 % to 100 % of the voltage rating. * 9. The change in the output current in response to a ±10% change in the input voltage in reference to the nominal input voltage (when the output voltage is in the range of 10 % to 100 % of the voltage rating ).
