冷阴极放电管用特性测试装置As-114B / As-128 / As-130
 | General tester that consists of a CCFL test bench and a main unit containing a power supply section and a measurement section. |
| The power supply section of the main unit outputs 0 to 6000Vrms*1 and 20mArms. The measurement section measures output voltage (Vo), lamp voltage (V  ), and lamp current (I) with a measurement accuracy of ±3%. |
| Equipped with a CV (constant voltage) mode and a CC (constant current) mode for driving CCFLs. |
| Equipped with a Vds mode that measures the lighting start voltage and discharge time log. |
| The CCFL test bench is designed taking high voltage and high frequency into consideration, so that the electrical influence on CCFLs will be minimized. |
| The CCFL test bench being apart from the main unit allows CCFL characteristic tests to be performed in a constant-temperature bath at -25ºC*2 to +105ºC. |
| We can make the CCFL test bench to accept both straight and bent lamps. |
| Equipped with an external inverter input terminal, Vo, V, and I can also be measured by actually driving an inverter to light CCFLs. |
| *1 : 3000Vrms to 6000Vrms, depending on the model. *2 : A test bench that can withstand a temperature of -30ºC can be also made. |
