Specimen power

(purchase selection)

1.equip DC12V or 24V or 36V,20A DC electrical source

2.reserve electrify interface terminal for customers equipment.

3.install the dustproof plug base,supply for AC 220V 20A power,the constant control timer to control power on or power off

Notes:The above are purchase selection for price,if customers need us to offer them,the price will be added;if not,we will not supply this for standard machine.

specimen vacuum facilities

(purchase selection)

1.the inside air pressure in test chamber is lower than outside,the vacuum pump is equipped for the specimen using(IP5/IP6 test)

2.If the air pressure in test chamber and outside is the same,do not need to equip the vacuum pump

Notes:If need to equip vacuum pump,the price need to add;

Power

supply

information

1)AC 220V single phase R、N+ protective grounding;voltage fluctuation range 10%

2)Frequency fluctuation range:50±0.5ＨZ；

3)Power supply method:TN-S or TT method

4)Grounding resistance of protection ground wire＜4Ω

5)User should equip with relevant capacity air switch or dynamic switch on the installation site,and the switch must control this machine only.When the electrified test sample is put in the test chamber,the power of the test sample should be connected with extra power,don’t use the power of this machine;
