High Flexibility Test Controller Card
TCC 1800-UE
-
The TCC1800-UE Test Controller Card is a generic control board for production testing of printed circuit boards (PCBs). The board is controlled by a command language on a PC to which it is connected via Ethernet.The TCC1800-UE is designed to work with positive voltages up to 24V. The card provides extensive IO: Analog and digital interfacing, counters, PWM outputs, bidirectional I/O, ethernet-, CAN, USB, SPI and I2C interfacing.

Precision Integrated Analog Front End, Controller, & PWM for Battery Test & Formation Systems
-
The AD8452 combines a precision analog front-end controller and switch mode power supply (SMPS), pulse-width modulator (PWM) driver into a single silicon platform for high volume battery testing and formation manufacturing. A precision instrumentation amplifier (in-amp) measures the battery charge/discharge current to better than ±0.1% accuracy, while an equally accurate difference amplifier measures the battery voltage. Internal laser trimmed resistor networks establish the in-amp and difference amplifier gains (66 V/V and 0.4 V/V, respectively), and stabilize the AD8452 performance across the rated operating temperature range.

Motor Termination Units
-
Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors cause voltage doubling at the motor terminals due to Travelling Wave Phenomenon as in transmission lines. The insulation of motor windings are prone to failure due to high voltage spikes if necessary precautions are not sufficiently taken. RC Type Output Filter Modules reduce these high voltage spikes to protect motors by connecting to stator terminals.
