The LBTEK Active Liquid Crystal Device Voltage Controller is designed to generate stable AC square wave signals for driving liquid crystal devices with precision and flexibility.
Output Waveform: AC square wave, fixed frequency 2000 Hz
Voltage Amplitude Range: 0–25 V (adjustable)
Dual-Voltage Output Mode: Modulation frequency adjustable from 0.5–150 Hz
Control Modes: Front panel control, external input control, or command-line control
DC Offset Monitoring: Real-time DC bias detection and correction to prolong device lifespan
This controller allows precise voltage and frequency control, ideal for driving liquid crystal variable retarders (LCVRs) and other active liquid crystal components. For detailed instructions, refer to the User Manual included with the product. Software for configuration and control can be downloaded from the “Software” section on the product page.
