Integrated Switching Amplifiers
Instruments Inc.’s custom line of Class-D PWM Switching Amplifiers are suited for high-power applications where efficiency and high power-density are critical, with upwards of 100 kW potential in a single cabinet, and which also may be combined in integrated amplifier systems for higher power levels. Output frequencies range from 20 Hz to 160 kHz, depending on transformer limitations. These amplifiers are suitable for both shipboard sonar systems and land-based low frequency radio transmission. While many models are available in standardized packaging, we offer complete customization of power handling, output specifications, and ultimately, chassis configuration. Single-channel and multi-channel configurations are available, and our technical expertise and experience allows us to deliver low-distortion amplifiers that are ruggedized to withstand the harshest conditions, including shock resilience in accordance with MIL-S-901D.
Linear Amplifiers
The tried-and-true Linear Amplifier line is Instruments Inc.’s seasoned line of Class-AB amplifiers. These standardized amplifiers range from benchtop units to large rack-mounted cabinets. They are capable of delivering up to 6500 watts (continuous) and 16.5 kW (pulsed) with a wide frequency band up to 100 kHz, with low THD even at full power. With the broad bandwidth and excellent performance, the Linear Amplifier line is perfect for in-lab testing of a wide array of transducers.
Voltage and Current Sensors
These instruments are electrically equivalent to wide band potential transformers and shielded current transformers. They can tolerate 1000 V of common mode voltage up to 200 kHz, while maintaining the specified accuracies of magnitude and phase. It is very important to sense both voltage and current at the same point in order to get accurate phase information. Our VITs are inserted between the outputs of the power amplifiers and the loads. The outputs of the voltage and current channels are single ended and have a 50 ohm source resistance. These analog monitor voltages have the same waveform as the voltage and current under test. Their magnitudes are accurately proportional to the original magnitudes, and the phase shifts between the voltage and current channels are matched. Phase information will remain valid if the low level output cables are matched in length, termination, and characteristics. These monitor signals are available at an MS type connector on the rear, as well as at BNCs on the front panel.
-
This is a single range version which uses differential voltage sense and average current sense. It produces a buffered, single ended low level output of 1 mV/V and 100 mV/A. It is limited to 2,500V. All other specs are the same as the VIT-13. A VIT-10M-6 is a 3U (5.25 inch) high rack mounting chassis which contains 6 channels. Units with fewer channels are available.
-
This instrument has four levels of sensitivity of voltage and current which may be selected locally or via isolated TTL logic. In addition, it has a current transformer in both the high and low leg which may be selected by a front panel switch.
