AE Techron 7224RLY Power Amplifier/Current Source
Description
AE Techron 7224RLY Power Amplifier/Current Source is designed to meet the demanding requirements of the power utility industry. Capable of outputting a 40 mSec pulse with up to 52 amperes peak current, the 7224RLY is powerful enough to put protection relays, fuses and other critical components through a full range of tests. The low noise floor, low distortion and minimal phase error of the 7224RLY make it the ideal amplifier for power grid modeling.
Features
- Up to 50 Ap (35A RMS) output power at 0.5 ohms
- Up to 158 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
