AE Techron 2105 Linear Amplifier
Description
AE Techron 2105 Gradient Amplifier is a high-power, DC-enabled linear amplifier and integrated power supply that offers a wide bandwidth and exceptional control of drift and distortion. The 2105 functions as a voltage or current source and operates using single-phase power, making it ideal for use in the lab or classroom. Its linear design provides a very-low noise floor and fast current rise times. Because the 2105 has no ripple noise, no synching with the console is required.
Features
- Up to 50 Ap, 150 Vp
- Current-mode response: DC-5 kHz (compensation dependent); Voltage-mode response: DC-20 kHz at rated power.
- Noise Floor (when Blanking circuit is enabled): 5 µA or less
- Current Settling Time on ramp of 0A to ±50A or ±50A to 0A: 20 µs to within 1.0A or 1%; 35 µs to within 200 mA or 0.2%
