NGOC MINH ISE CO., LTD

Chroma 19036 is the industry's first Wound Component Electrical Safety Test (EST) Analyzer that combines the functions of impulse test, hipot, insulation resistance and DC resistance measurements. It has 5kVac/ 6kVdc high voltage output, 5kV insulation resistance, 6kV layer short impulse voltage and 4-wire DC resistance measurement that can comply with the wound components test demands by providing maximum 10 channels output for multichannel scanning tests to save time and labor costs.

The Chroma 19301A impul se Winding Tester combines high & low inductance test technologies, has a maximum impulse voltage of 1000V, and a high speed sampling rate of 200MHz which satisfies most of the test requirements for power inductor products with a wide inductance range from 0.1uH to 100uH. The built-in functions of Area Size Comparison, Differential Area Comparison, FLUTTER Value, LAPLACIAN Value, ΔPEAK o r Δ P EAK RAT IO, P EAK RAT IO a n d ΔRESONANT AREA functions are able to inspect coils for poor insulation effectively.

Chroma 19200 can perform high / low voltage switch and scan all safety tests by EST Analyzer (Chroma 19032) inputs such as withstanding test; Some modules support 20A for Leakage Current test and Function Test; GB & GBF modules support 40A and Ground Floating.

The 19572 are instrument dedicated to measure the grounding resistance within the range of 0.1~510mΩ. Its compact and easy to operate feature is most suitable for the grounding test in production line. By supplying high reliability and stability test results with built-in resistance compensate function; it is an economical and useful grounding tester.

The Chroma Hipot Tester 19050 series provide 3 models for choice. The 19052 for AC/DC/IR Hipot testing and insulation resistance (IR) measurements, the 19053 which combines both AC and DC Hipot tests and IR measurements with 8HV scan channel capability into a single compact unit, and the 19054 which combines both AC and DC Hipot tests and IR measurements with 4HV scan channel capability into a single compact unit. The front panels of the fevers make them easy to operate. Digital display and user friendly control allows test parameters and limits to be set easily without the high voltage activating.

The 19032/19032-P are 5 in 1 Production Safety Analyzer. It can perform AC/DC Hipot, insulation resistance, grounding resistance and dynamic leakage current 5 safety test functions for electronic products. The dynamic leakage current scan device (A190305/A190307) can be connected externally or built in to 19032 Series. It is capable of measuring the complicate safety requirements with easy installation and operation, and is the finest auto safety tester to increase production test efficiency.

Chroma 19501-K Partial Discharge Tester combines Hipot test and PD (Partial Discharge) detector functions in one instrument. The device is capable of a maximum 10kV AC output with leakage current measurement range of 0.01uA to 300uA and a minimum Partial Discharge detection of 1pC. The tester is specifically developed to test high voltage semiconductor components and high insulation materials. The 19501-K design meets the IEC 60270-1 and IEC 60747-5-5 standards, and has built-in IEC 60747-5-5 test methods for use. It not only satisfies the production test requirements for opto-coupler products, but also gives users a friendly and convenient operation interface. 

The Chroma 19311 series Battery Cell Surge Tester is designed for testing the insulation quality between the positive and negative plates of the lead-acid battery cell. This is done by applying a high voltage surge/impulse before the electrolyte injection. Its output voltage can reach up to 6kV. It also has four terminal measurement and 200MHz sampling rate. The Chroma 19311 series has single channel (19311) and multi-channel (19311-10) tester.
