Optimized for Space-Constrained HV Applications

The LQHDR 200kV/5kΩ damping resistor delivers essential oscillation suppression in compact high-voltage test environments. Designed for 50Hz systems at 0.05A current, this space-efficient solution (Ф400×1000mm) provides reliable performance in transformer testing, cable diagnostics, and research labs where footprint matters. With its 1-hour continuous operation capability and lightweight design (<40kg), it's ideal for mobile test setups and benchtop configurations.
