Elsys TranAX 3.4

Data-Acquisition Software Adds Application-based Features

Elsys has added new features to its TranAX 3.4 (formerly TransAS) client-server-based transient recorder application and signal analysis software. The software remotely controls data acquisition equipment over 1-Gb LANs from any location worldwide. Applications that benefit from the enhancements include ballistics measurement, crash testing, structural health, seismic research, field testing, stray voltage detection, variable-frequency drive diagnosis, connector conductivity testing, high-voltage switching, and rail and automotive control and monitoring.

Video recordings in common formats (e.g., AVI, MP4, MPG, etc.) can be imported and synchronously displayed with actual measurements signals. This enables you to use a high-speed camera simultaneously on screen to analyze measurement data and recordings. To analyze acoustic signals, frequency spectra can be displayed as standard, octave, or one-third octave. Audio signals can be weighted in dB-A or dB-C.

TranAX 3.4’s redesigned formula editor features more than 60 mathematical functions and includes an unlimited number of math traces for extensive signal analysis. Program functions (e.g., if/then, loops, end, true/false, etc.) make computing post-measurement results from multiple, simultaneous and/or sequential recordings easy and efficient. Events benefiting from these functions include multiblock recordings, a series of stored measurement files recorded by auto-sequence, or single-shot acquisitions with multiple events in one record.

The software enables application-specific computing algorithms to be stored and recalled for later use. Programming can be done separately in a higher-level language under Microsoft .NET. The resulting software code can then be integrated as DLL in TranAX.

iWatt iW3630

SSL LED Driver Optimized for Commercial & Wireless Lighting

The iW3630 is a two-stage, digital AC/DC LED driver with 45-W output power that supports a PWM digital dimming interface for wireless solid-state lighting (SSL) applications. The iW3630 utilizes iWatt’s Flickerless technology to eliminate flicker across the entire 1% to 100% dimming range, while providing tight, ±5% LED current regulation. Flickerless technology incorporates a power factor correction (PFC) circuit comprised of a chopping circuit that ensures a high power factor and virtually eliminates the input line-voltage frequency component

The iW3630’s built-in isolation transformer driver works directly with 0-to-10-V dimming systems, eliminating the need for additional driver circuitry components and microcontrollers. Its PWM digital interface simplifies integration into wireless lighting systems.

The driver offers a low total harmonic distortion (THD) of less than 15% to meet stringent global energy regulations, along with a built-in over-temperature protection (OTP) and derating function to improve a system’s predictability and reliability. In commercial and wireless applications, the built-in over-temperature protection and derating function eliminates the need for additional components for heat control. In addition, iWatt’s PrimAccurate primary-side control technology eliminates the need for a secondary-side regulator and optical feedback isolator, while iWatt’s EZ-EMI technology simplifies electromagnetic interference (EMI) filtering to further minimize the external component count.

The iW3630’s digital control architecture simplifies ballast driver designs by enabling it to adapt to wide input and output conditions. Therefore, one configuration can support a range of LED string lengths to cover the entire output power range.

The driver’s on-chip over-temperature protection and derating feature monitors the temperature inside the ballast. When thermal conditions reach a point set by the system designer, the iW3630 LED driver automatically reduces the current drive to the LEDs, lowering the power dissipation and resulting in a cooler overall operation. This reduces the risk of thermal runaway, ensures the electrolytic capacitors in the lighting system’s temperature rating is not exceeded, and enables a predictable operating life.

The iW3630’s built-in protection features include LED open/short, input overvoltage, overcurrent, and current-sense resistor short protections. Additional features include 3-to-45-W output power and greater than 0.95 power factor.

The iW3630 is available in a standard, 14-lead SOIC package. It costs $1.16 in 1,000-piece quantities.
