Eeach one voltage stabilizer one wooden case packing box.inside we first used one plastic plastic bag.then used 4pcs foam by 3.5mm thinkness protect.

1.Quality control

automatic voltage regulator / automatic voltage stabilizer quality control for very customer very important.we control quality from very one spare part.especally coil power and PCB board. see picture below.if you want to know more information how about our how to keep stabilizer quality good.pls contact our email.

2. Quality Guarantee

we give our customer automatic voltage regulator / automatic voltage stabilizer voltage regulator/voltage stabilizer quality guarantee period 2 years if proper loading we give customer 5 years and adopt our technician suggestion(AT 5 years period if input voltage often fluctuation only change carbon brush ).every voltage stabilizer we first testing part quality then assmbel finished testing output and loading testing.after testing finished we make dynamic testing.after packing we testing again.see below our testing equpiment.

above is loading testing coil power.all customer automatic voltage regulator / automatic voltage stabilizer we must make loading testing.

above one is automatic voltage regulator / automatic voltage stabilizer dielectric Strength Tester.another one is automatic voltage regulator / automatic voltage stabilizer no load current testing machine.

3. Feeback

If automatic voltage regulator / automatic voltage stabilizer voltage stabilizer get any problem or have any specially design stabilizer inquiry.we will reply customer within 24 hours.bcos our sale person is technician.like three phase stabilizer output need 220V.general is 380V.surge protect and over-loading protect.full power loading design.silicon area and winding wire size design specally.see below picture with isolation transformer control

above automatic voltage regulator / automatic voltage stabilizer is line conditionner protect

4.OEM/ODM available

we accpet customer OEM or ODM.customer send to our your logo and company name and packing box design.if no have design.we can design for customer.then printing voltage stabilizer panel logo and company name.samll power carbon box we printing customer logo and company too

5.we accpect sample order testing our quality.

at make sample before we confirm all specification no problem.first we will testing by our sale person.after we testing finished.we will send to customer check quality.small power sample we give customer sample for free.customer pay shipping cost.

YUEQING ZHONGMING ELECTRIC CO.,LTD located at chaoyang industrial Zone, Liushi,yueqing,Wenzhou, Zhejiang, China. Our company main products is voltage stabilizer. variable transformer(contact regulator) and isolation transformer. We ensure Best quality, Competitive Price and Strong Life Time After Sales Service.our born in 2009 years.and our engineer and boss workring stabilizer factory already have 15 years.

1.About Our Voltage stabilizer how to make quality no any problem.

first we do voltage stabilizer inside main part PCB board and coil.we have winding machine and Dipping paint(immerse machine).silicon testing no loading current machine.

only we receive customer we first will be send to detail spec of coil size and weight and silicon area and copper wire size for our customer reference.after custome confirm okay.then we do one sample testing.after testing okay we will begining make all production order.bcos our boss working stabilizer factory already have 10 years experience.
