AE Techron 7212 Power Amplifier DC – 250 kHz 440W
Description
AE Techron 7212 Power Amplifier DC – 250 kHz is a four-quadrant, 0.44 kVA, DC-enabled amplifier that was created to meet the exacting requirements of the power utility industry. It features a DC to 250 kHz bandwidth, low noise floor, fast slew rate and a 113V RMS potential. The 7212 can be combined to form a 3-phase Y voltage source, and has a wide range of field-configurable options.
A single 7212 can output a 40 mSec pulse with up to 30 amperes peak current. In continuous operation, a 7212 can provide 440 watts RMS of output power. If more voltage is needed, up to four amplifiers can be combined in series and operate as a single system.
The 7212 can operate in either voltage or current mode and can be configured by the customer for high-voltage/low-current, medium voltage and current, or low- voltage/high-current applications. It provides very low noise and fast slew rates, and can safely drive a wide range of resistive or inductive loads.
Features
- Up to 113V RMS at up to 4A
- Pulsed output up to 30 Ap
- 430 watts RMS continuous output
- Low noise floor of only 300 µV
- Fast, 50 V/µs slew rate
- System output of over 1,700 watts is possible with multiple, interconnected amplifiers
