Chroma Group HiPot GUARDIAN 500VA PLUS

The GUARDIAN 500VA PLUS is a HiPot from Chroma. HiPot, or high potential, is a class of electronic test equipment used to verify electrical insulation. Engineers use HiPot-testing instruments on cables, wires, circuit boards, appliances, electric motors, and transformers. As a product ages, its insulation may break down and result in current flow leakage. HiPot testers keep engineers safe from current leakages by detecting gaps and defects in the electronic device. Dielectric Testers, Insulation Testers, and Megohmmeters are similar to HiPot testers. Popular manufacturers include Biddle, Megger, Fluke, Associated Research, Quadtech, Instek, and Slaughter. Additional Features: 500V output rating HiPot: AC 5kV/100mA - DC 6kV/20mA Insulation: 5kVmax - 1Mω~50Gω Floating output complies with EN50191 Corona Disharge Detection Programmable AC HiPot Frequency: 50 Hz - 600 Hz Total and Real Current Measurement Open Short Check (OSC) High Frequency Contact Check (HFCC) Ground Fault Interrupt Standard RS232 and USB Interfaces Standard HANDLER interface Optional GPIB Interface Key Lock on fail Programmable voltage & test limit Front and Rear Output Connectors LabView Drivers are available CE Mark Applications: High Voltage Capacitor, Photocoupler & Insulation Materials Transformer safety testing Generator/motor safety testing The Chroma GUARDIAN 500VA PLUS HiPot Analyzer is designed for applications requiring a 500VA output transformer capacity with 100mA AC current output. The analyzer has both HiPot test and analysis modes making the unit flexible for both production and R&D applications. The tests of AC/DC/IR can be programmed to 5000 VAC, 6000 VDC and 5000 VDC for IR. The full floating output complies with the EN50191 requirements for operator safety. The Guardian 500VA Plus features a large LCD screen for programming and measurement. Ground Fault Interruption and Floating Output features can also be used for operator protection. The HiPot tester is equipped with an output to monitor the arc signal with an oscilloscope. The Guardian 500VA Plus is equipped with a new Function called High Frequency Contact Check (HFCC) besides the Open Short Check (OSC). These two features are designed to determine if a connection to the product has been made during testing or prior to testing. HFCC operates during testing and OSC is used as a step prior to HiPot or IR testing. OSC operates by measuring the capacitive load (Cx) of the DUT from tens to thousands pF and looking for a change in capacitance from the nominal capacitance of the DUT to determine connection. HFCC (High Frequency Contact Check) is a new measurement technology for contact check. HFCC is able to be performed during the HiPot test using a high frequency, around 1 MHz, for improved test time on the production line.
