Profile:
The KDZR-40L DC motor inter piece resistance tester is a specialized equipment for DC motor detection. It can effectively detect whether the welding between the commutator and winding is good, and whether there are any adverse phenomena such as open circuit or short circuit in the winding by detecting the inter piece resistance of the DC motor armature. This instrument uses a high-precision constant current power supply and is an equipment for the production and maintenance of DC motors.
The testing of inter chip resistance in DC motors is an effective means of detecting the balance of stator coil resistance. In the preventive testing regulations for power equipment, there are specific provisions for this test. The inter chip resistance tester consists of a constant current power supply, voltage detection circuit, and control circuit. The output current is adjustable and stable, and the voltage value is displayed on a dot matrix LCD screen. The data is read directly, greatly improving the measurement speed.
Features:
1. The whole machine is controlled by a high-speed microcontroller, with a high degree of automation and easy operation.
2. Adopting high-frequency switching power supply technology, the output current is large, suitable for measuring large and medium-sized DC motors.
3. The protection function is complete, which can reliably protect the impact of back electromotive force on the instrument, and the performance is more reliable.
4. It has an audible discharge alarm, clear discharge indication, and reduces misoperation.
5. Adopting a vertical chassis structure for easy on-site use.
6. Intelligent power management technology ensures that instruments always operate at their minimum power, effectively reducing internal heat generation and saving energy.
7. Dot matrix LCD, Chinese menu, printed output.
