Detailed Product Description

Equipment Experimental Device

Technical features:

(1).The electro technical instruments used here are national patent products, which have high precision, good overload capacity. The AC meters here have wide frequency range, absolute value reading, overload protection and automatic alarm and recording. The internal impedance of the ammeter is close to zero. So they are idea instruments 

(2).The safety protection is in accordance with the recent national standards,Ground , meet national standard: GB4706,  Current-type leakage protection device, meet national standards GB6829,GB13955. The leakage of current is less than 30mA, the power can be shut off within 0.1s,Uses the fully closed strong electricity protection sockets and the fully closed strong electricity protection conductors with insulating sleeves,The surface board is made of high insulation, high intensity and high temperature resistant density board,We add control and protection units for the three phase power supply

(3).Equipped with ZQ16 ergometer and ZQ25 encoder which was developed by our company.

Digital display of rotating speed, torque and power, 0.5 level precision

The experiment platform: High quality steel sheet, double layer spraying plastics, high insulation density board, with 4 wheels down the bottom and 4 fixing and supporting devices.
