MESSRS : Specification Comparison CUSTOMER'S PRODUCT NAME: TDK PRODUCT NAME: DC/AC INVERTER UNIT CXA-0547 TENTATIVE TDK-Lambda Corporation PREPARED BY APPROVED BY AUTHORIZED BY April 27th, 2010 April 27th, 2010 April 27th, 2010 K.Imai K.Yamaishi H.Masuoka DWG.No. CTR-3911-X The difference between CXA-0349 and CXA-0547. *Product summary CXA-0547 expands operating temperature range to -20C~70C compared with CXA-0349. At the same time, all components is mounted by machine. So human error reduces and reliability is improved. Input fuse rating is changed because the lamp impedance at low temperature is high. This product is expected stable supply to the customer by replacement of terminated components. TE NT AT IVE 1.Appearance, dimension and pin configuration 1-1.Appearance The appearance of CXA-0547 is changed as follows because several component is changed from CXA-0349. CXA-0349 CXA-0547 The CXA-0349 has several hand mount components indicated in All of components are mounted by machine in CXA-0547. . 1-2.Dimension and Pin configuration Dimension, Pin configuration, Mounting hole and Input Output connector are not changed.
