RLY Amplifiers
Robust Amplifiers for Relay Testing
AE Techron’s Relay Testing amplifiers were created to meet the demanding requirements of the power utility industry. With models capable of outputting up to 200 amperes peak current, these Relay Testing amplifiers are powerful enough to put protection relays, fuses and other critical components through a full range of tests.
All models are capable of a controlled-current bandwidth of DC – 10 kHz and a controlled-voltage bandwidth of DC – 100 kHz. Low noise floor, low distortion and minimal phase error make these amplifiers ideal for power grid modeling.
