Solid State Synchro Control Transformer and Solid State Resolver Control Transformer

SCT-RCT Series

-

Computer Conversions Corporation

SCT-RCT Series - Computer Conversions Corporation

The SCT Series are low cost, miniature, solid state control transformers designed for military and industrial control applications. They will directly replace conventional electromechanical control transformers & thus provide digital control to existing analog servo systems. They simultaneously accept a 3 wire synchro input (0) and a digital angle input (0), and provide an ouput which is the sine of the difference between these two input angles (A sin wt sin (0-0) ("wt" is the synchro excitation frequency).

Dytronic Primary Transfer Ultra Stable Standard

RD-22 Ultra

-

Radian Research, Inc.

RD-22 Ultra - Radian Research, Inc.

The RD-22 Dytronic Primary Transfer Ultra Stable Standard represents the state-of-the-art technology in a commercially available AC transfer reference. The Ultra Stable RD-22 is a variant of the RD-22 Primary Transfer Standard that has been optimized for 120/240 V @ 5A operation to provide optimum stability. In a stable test environment, repeatability for a 10-second test of ±0.6 µWh/VAh is attained at 120 V and 240 V at 5A inputs with a 95% confidence interval. A typical experimental 2 repeatability of less than ±0.25 µWh/VAh is achieved. In a stable test environment, a reproducibility of ±2 µWh/VAh over a five-day interval is attained at 120 V and 240 V at 5A inputs with 95% confidence interval.

AC Calibration Standard

1U647-001

-

Sigma Tek, Inc.

1U647-001 - Sigma Tek, Inc.

The 1U647-001 is a low cost calibration standard used to determine if a 1U632-100 or a 1U663-100 DMU requires factory calibration. Its portability makes it ideal for field-testing. The standard generates signals that simulate the aircraft’s resolvers, rotary variable transformers (RVTs), and linear variable displacement transformers (LVDTs). The unit also generates a pulse width modulated (PWM) signal, and routes the output of an ARINC 429 source to the different DMU input channels. The calibration standard connects directly to the DMU and replaces the output signals of an active extender card. Discrete switch settings simplify testing. The unit is housed in a rugged aluminum case.
