CJP-20A DC motor inter-chip resistance tester

Estimated delivery : 30 Days; MOQ : 1 PCS
Product Introduction Overview :
The test of inter-chip resistance of DC motor is an effective means to detect the balance of stator coil resistance. The preventive test procedures for power equipment have special provisions for this test. The inter-chip resistance tester consists of a constant current power supply, a voltage detection circuit and a control circuit. The output current is adjustable, the current is stable, and the voltage value is displayed on a dot matrix LCD screen. The data is directly read, which greatly improves the measurement speed.
The DC motor inter-segment resistance tester is a special device for DC motor detection. It can effectively detect whether the welding between the commutation segment and the winding is good, whether the winding has open circuit, short circuit and other undesirable phenomena by detecting the inter-segment resistance of the DC motor armature. This instrument uses a high-precision constant current power supply and is the preferred equipment for DC motor production and maintenance.

Features :
The whole machine is controlled by a high-speed single-chip microcomputer with high automation and easy operation.
It adopts high-frequency switching power supply technology, has large output current, and is suitable for measuring large and medium-sized DC motors.
The protection function is perfect, which can reliably protect the instrument from the impact of reverse electromotive force, and the performance is more reliable.
With audible discharge alarm and clear discharge indication, it can reduce misoperation.
It adopts a vertical chassis structure, which is convenient for on-site use.
Intelligent power management technology ensures that the instrument always operates at minimum power, effectively reducing internal heating and saving energy.
