Product description

Operating with repetition rates from 1–4.5 kHz, output voltages from 1.5–4.5 kV, and rise and fall times of 4–7 ns with pulse widths of 150 ns–5 μs, the Q-Drive is fully self-contained with the power supply and all control circuitry, needing only 24 VDC and a trigger signal to operate.

Housed in a compact 100x125x50 mm (4x5x2") aluminum case, the driver has a full suite of controls, indicators, and remote control features. It operates from an external 24 VDC source (power adapter included).

A unique feature of the driver is its differential bipolar output – reducing voltage to ground and shock hazard, an important feature in a laboratory
environment. The cables from the Pockels cell leave from the back of the case, keeping them away from hands at the front panel. The driver outputs are protected against short-circuits.

The driver is designed for reliability with low component stresses, the highest quality components, and the use of US Navy derating standards.

The unit is ideal for evaluating G&H's OEM driver technology as both drivers share the same electronic design.
