http://www.whgdmk.com/aspcms/product/2014-4-30/159.htmlTKDCW-Ⅱ DC power supply ripple tester (ripple table) of the Wuhan Branch Electric Power Co., Ltd. Ming specially developed TKDCW-Ⅱ DC power supply ripple tester accurate real-time content on the DC power supply ripple and ripple factor to do the whole monitored. In recent years, a large number of valve-regulated battery charger on the performance put forward higher requirements. Former State Ministry formulated the relevant control standards. On the charger voltage accuracy, steady flow accuracy, ripple factor clear requirement. Damage to the battery is often caused by too much ripple factor. Charger in the long run, and its total ripple factor changes. To measure the ripple factor and ripple content (AC ripple amount) of each group charger, product nickname DC power supply ripple coefficient tester DC ripple ripple table tester product parameters a measuring voltage range: 0 ~ 300VDC, measurement accuracy better than 1%, resolution 0.1V; 2 ripple voltage range: 0 ~ 200mV, the measurement accuracy of better than 2%, resolution 0.1mV; 3 ripple factor: 0 ~ 99.999% 4 LCD LCD 5 Power: 220V Product Characteristics ① using new high-speed sampling chip, high-speed signal processing. ② small size, light weight, high precision, easy to carry features. ③ sampling rate of 1000KHZ, can fully monitor the DC ripple content. ④ with RS232 communication function. ⑤ meet all of the DC power supply 0-300V. ⑥ comprehensive real-time monitoring of the DC voltage, ripple, ripple coefficient.
