7224RLY
7224RLY
AE Techron
For Protection Relay Production Testing and Commissioning
Up to 52 Ap Current Source
- High compliance voltage allows the 7224RLY to drive electromechanical relays directly
- Maintains phase accuracy for any load from a dead short to 2 ohms
- Front panel indicators for rapid assessment of amplifier status
- Protection circuitry protects from input overloads, improper output connection (including shorted and improper loads), over-temperature, over-current, and supply voltages that are too high or low
The 7224RLYwas created 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.
Key Performance Capabilities:
- 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
