High Voltage Pulse Modulator Driver ±4kV
The HVPD Series Bipolar High-Voltage Driver is a turnkey unit that delivers sharp electrical pulses of up to ±4kV with a 1 MHz bandwidth, ideal for driving large aperture electro-optic (EO) modulators. The unit includes a manual voltage adjustment knob, BNC pulse trigger input with two control modes — normal and analog —selectable via a switch. For high-voltage and high-repetition-rate operation, integrated water-cooling ports ensure thermal stability and reliable performance. It comes with cables for connecting to Our EO modulators. This is a bipolar driver, meaning the voltage polarity on the electrodes constantly flips to prevent DC charge buildup (ionic migration) inside the EO crystal. On the first pulse, Pin A is +V and Pin B is -V. On the second pulse, the polarities reverse: Pin A becomes -V and Pin B becomes +V.
