SAFETY TEST OF VIDEO PRODUCT (IEC 60065)

Video products are inclusive of DVD recorder, LCD TV, audio amplifier, stereo and etc. These products have mass power output with separate

safety standards. The main circuit design of mass power is signal output terminal beside temperature increasing and heat dissipation of electronic

component. Open voltage of some video products is over 35Vac peak or 60Vdc peak that performs U1 dynamic leakage current test is required.

U1 measurement circuit is added to the 19032 and P1/P2 measurement point is provided that to comply with the requirement of safety standard

test.

Main Test Item

• Open Short Check

• Ground Bond

• AC/DC Hipot Test

• Earth Leakage Current Test

• Output LC Test

Product Application

Household appliances consist of oven, refrigerator, television, juicer and coffee machine that human may contact at any time. To ensure the safety

of users, all products should do electrical safety tests. Except for basic Hipot test, dynamic leakage current has various test regulations by different

ground modes and operation methods.The regulations are as the table shown below.
Main Test Item

• Open Short Check

• Ground Bond

• AC/DC Hipot Test

• Earth Leakage Current Test

19032 + 6000-07 is a solution for electrical safety and function test of medical

equipment. The safety standard of medical equipment is very strict. Since the

medical equipment contacts the body of doctor and patient oftenly, it makes various

electrical safety tests that cannot be ignored especially the leakage current test

which has already become the most important test in electrical safety test.

The safety standard of medical equipment has various of leakage current tests.

Inaddition, normal / reverse / single fault normal / single fault reverse four powers

and earth switch, made the safety test difficulty and complexity further. The basic

measuring circuit for the enclosure leakage current is as the figure. Moreover,it

shows here measurment Type BF and CF is a special requirement for medical

equipment. DC leakage current should be isolated separately and limited within

50uA limited which mentioned in medical safety standard. The function has

already been added to the 6000-08 LC scanner.Chroma 19032 + 6000-07/08 offer

programmable editing and software support, That all you to test medical product

without missing procedure so it saves the test data directly to provide you the best

test solution.

ELECTRIC VEHICLE SAFETY TEST

Automotive industry has already converted from internal combustion engine

power to electric power. Because the voltage of electric vehicle will be maximum

up to 600V when operating, its safety issue . To avoiding electrical injury is also

important Chroma 19032 is the best solution for electrical safety tests of connecting

wire and connector of electric vehicle, adapter, battery, charging station system.

Test Item

Withstand voltage test: Various insulation terminals, primary and uncharged metal,

withstand voltage between primary and secondary.

Leakage current: All metallic parts can be touched on the system reguired to test

earth leakage current during dynamic operation.

Ground test: Ground protection connection should use 25A/60Hz current to test

resistance, it cannot higher than 100mΩ.
