2110 GRADIENT AMPLIFIER
The 2110 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 2110 functions as a voltage or current source, making it a good choice for use in the lab or classroom. Their linear design provides a very-low noise floor and fast current rise times. Because the 2110 has no ripple noise, no synching with the console is required.
The AE Techron brand is known throughout the world for its robust, low-noise gradient amplifiers as well as its product service and support.

2110 Pulsed Output
Pulse testing performed with unit operated in Controlled-Current mode with a load equal to 500 µH + 200 mΩ and at 25°C ambient temperature.
|Output (±A Peak)||
PULSE DURATION / OFF TIME (ms)
|∞(DC)||500 / 500||100 / 100||10 / 20||170 / 1000||25 / 1000||4 / 100|
- Output of 110 amperes peak, 195 volts.
- 4-quadrant linear design.
- Blanking feature lowers the noise floor on the amplifier by shutting down the output stage. This action occurs in less than 10 µs.
- Current mode response: DC-5 kHz (compensation dependent); Voltage mode response: DC-20 kHz at rated power.
- Robust, linear power supply results in extremely low noise; bi-level switch design limits heat dissipation to output devices.
- Provides precision control of output offset, DC drift and gain linearity.
- Protection circuitry guards against input overloads, improper output connection (including shorted and improper loads), over-temperature, over-current, and supply voltages that are too high or low.
- Shipped ready to operate from 208-volt (±10%) three-phase AC mains. 400-volt model available on request.
