Two test way for High Frequency Adjustable Reference Ballast(25KHz)

HCS-105A has two functions: one is high frequency ballast; second is high frequency digital power meter. As above picture show, after we connected instrument with test samples, high frequency constant power source will output high voltage to start test lamp (tube), high frequency constant power source output frequency range is 20KHz-26KHz, it can provide continuously adjustable current 100mA-500mA. The obvious disadvantage of IEC equivalent test method(constant current test method) is high frequency constant power source will output internal impedance, and mass output impedance will cover normal electronic parameters of test standard lamp (tube), the accuracy tolerance around 5%-30%. This system is main for small test lab and tube manufactures.

We have a lot of customers who bought the , like Netherlands and China branch , At the same time, lots of customers show their interesting in . The reason why we can win so many trust and support from the world famous companies is because we always practice the motto right product, right price and right service. From the feedback, Lisun enjoy good reputation in the world market. And we will always provide the high quality products and superior service to all of our customers.
