HDVR-1600kV/20mA HVDC Protection Resistor

Product Overview

The HDVR-1600kV/20mA is a precision protection resistor designed for ultra-high voltage DC systems up to 1.6MV. Its 100kΩ resistance and robust construction provide reliable over-current and over-voltage protection for critical test equipment.

Technical Specifications

Protection System Design

Dual-Resistor Configuration

• AC Side: 10kΩ protective resistor

• DC Side: 100kΩ main limiting resistor

• Position-adjustable design with secure locking

Protection Mechanism

Without Protection
