Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator. They are used to prevent damage to the inverter circuits attached to rotor side when a fault occurs in the grid. DFIG power converter, which has a restricted over-current limit, needs special attention during faults in the grid. If the rotor current or DC link voltage reaches the threshold value, crowbar resistors disconnect the converter in order to prevent the generator turning into a squirrel cage induction machine. By crowbar resistors, the DFIG could stay connected to the grid and continue its operation.

The Rotation Link SAS
Capsule Slip Rings are compact slip rings that can be used in a wide range of applications. They integrate rotor, stator, brush block, bearings and casings and enable the transmission of power and data through rotating systems. They are ready to be integrated into customers’ systems and provide built-in protection from humidity and dust.

5000EG-series -
Sigma Tek, Inc.
The 5000EG gyro is based on our air-driven 5000B model, whose proven reliability has made it the industry standard for many years. There are two models available: 14 and 28 VDC. The rotor is precisely machined from a heavy-metal tungsten alloy, which has a higher mass than brass, contributing to the instrument’s demonstrated stability. The electric motor is driven by a built-in power inverter, and has an integrated air-erection mechanism. A warning flag is deployed upon loss of primary power. During acrobatic flights or short stops, the gyro’s mechanism can be caged whenever the knob is pulled.

The PXIe‑4112 is a programmable DC power supply with isolated outputs. It helps simplify the task of designing automated test systems for a wide range of applications—from aerospace and defense to automotive and component test—by eliminating the need to mix multiple instrumentation form factors in a given test rack. It also has standard output disconnect functionality that allows isolation from the device under test (DUT) when not in use, and remote sense to correct for losses in system wiring.

PXIe, Rubidium PXI Synchronization Module - The PXIe-3352 generates high-stability clock signals for PXI or third-party instrumentation. It provides a high-accuracy sine wave, square wave, or 1 pps output, and it includes a built-in GPS receiver (external antenna required) to discipline the rubidium oscillator for long-term stability. The front panel DC power input maintains power to the rubidium oscillator if the PXI chassis is powered off, keeping the rubidium oscillator stable over time and eliminating the effects of retrace. The GPS receiver also maintains its location information during power off for fast system bring up.
