Vitrek 959i Ground Bond Hipot Tester

Overview

The Vitrek 959i is a specialized ground bond hipot tester from the 95X Series, designed for electrical safety testing of components requiring high-amperage ground bond verification. It delivers 40 Amperes of output current with test times from 20 milliseconds to 1000+ seconds, precision 4-wire milliohmmeter capability, and pico-ampere-level leakage measurement to detect even the smallest electrical defects.

Key Features

• 40 Ampere ground bond test output with programmable test times from 20 mS to 1000+ seconds
• 4-wire milliohmmeter with 100µΩ resolution and range from 100µΩ to 100K ohms
• Pico-ampere leakage current measurement for detection of minimal leakage
• Safety Fault Interlock (SFI) with high-speed shutdown for operator protection
• Test Lead Safety Sense (TLSS) technology continuously verifies proper lead connection
• Recessed start switch prevents accidental activation
• Dual Coldfire microprocessors with dual DSPs for fast test processing
• 100 test sequences with up to 100 steps each, selectable via front panel or Ethernet
• Multiple interfaces: Ethernet, RS232, Digital I/O, USB Printer/Scanner control
• Optional GPIB interface and high-voltage scanner control up to 256 switching points
• Test-specific fixture and cable compensation to eliminate offset errors

Applications

• Ground continuity and bond testing in manufacturing and assembly
• Electrical safety compliance testing per EN 61010-1 and EN 61326-1
• High-amperage ground bond verification for heavy industrial equipment
• Multi-point testing with optional scanner modules for parallel testing
