AE Techron 7796RLY Power Amplifier/Current Source
Description
AE Techron 7796RLY Power Amplifier/Current Source is designed to meet the demanding requirements of the power utility industry. Capable of outputting up to 200 amperes peak current, the 7796RLY is powerful enough to put protection relays, fuses and other critical components through a full range of tests. It is capable of a controlled-voltage bandwidth of DC – 100 kHz and a controlled-current bandwidth of DC – 10 kHz. The low noise floor, low distortion and minimal phase error of the 7796RLY make it the ideal amplifier for power grid modeling.
Features
- Up to 200 Ap (141A RMS) output power at 0.5 ohms
- Up to 183 Vp output voltage
- Standard transconductance of 20 ±0.2% from short to 1-ohm load
- Residual noise of less than 2.5 mA peak, from 40 Hz to 600 Hz
