  • Page 1 TENTAT TDK-Lambda EZA2500WW series Quick Manual /Practical(I) EZA2500W-32048 Quick Manual Practical Volume I BEFORE USING THE POWER SUPPLY UNIT (Common) Be sure to read this instruction manual thoroughly before using this product. Pay attention to all cautions and warnings before using this product. Incorrect usage could lead to an electrical shock, damage to the unit or a fire hazard.
  • Page 2 TDK-Lambda EZA2500W series Quick Manual / Practical(I) • For products without built-in protection circuit (element, fuse, etc.), insert fuse at the input to prevent smoke, fire during abnormal operation. As for products with built-in protection circuit, depending on usage conditions, built-in protection circuit might not work.
  • Page 3 TDK-Lambda EZA2500W series Quick Manual / Practical(I) Over view of Quick manual Practical Volume I In Quick Manual Practical Volume I, We will explain a series of procedures for starting up EZA2500W, how to start via RS485, and how to start via external connector CN.
  • Page 4 TDK-Lambda EZA2500W series Quick Manual / Practical(I) 1) Explanation of terms of EZA In EZA, terms unfamiliar with other power supplies are used in instruction manual etc. I will explain the main ones below. ① CV: Constant Voltage. In the case of EZA, control to make the voltage on the high-voltage side or the low-voltage side of EZA constant is called CV control.
  • Page 5 TDK-Lambda EZA2500W series Quick Manual / Practical(I) following methods a) to c). a) Command via RS - 485 b) Set pin 11 of CN to short with signal ground SG ⇒ open. C) Press the reset button on the front panel.
  • Page 6 TDK-Lambda EZA2500W series Quick Manual / Practical(I) 2) Explain of Terminal Connection and Panels EZA2500W terminals and Panels are shown in the figure below. Please check with each item of Quick Manual Basic Guide p5-6, Operation Manual. ① LED of Indicator The LEDs (3 pcs) indicates operating status of EZA2500W.
  • Page 7 TDK-Lambda EZA2500W series Quick Manual / Practical(I) 3) What can be done via RS-485, what can be done with External Signal Connecter EZA series can control all the following functions with RS-485, and all parameters can be set with RS-485. The Functions in bold can also be controlled by CN rather than RS485.
  • Page 8 TDK-Lambda EZA2500W series Quick Manual / Practical(I) 4) When using via RS485 When operating the EZA via RS-485, follow the procedure below according to the items in the Quick Manual Basic Part 7, 8 and Operation Manual. ① Set EZA to operation via RS-485.
  • Page 9 TDK-Lambda EZA2500W series Quick Manual / Practical(I) ③Set parameters of EZA. Set parameters of EZA via RS-485. Refer to the communication manual for how to set parameters. Refer to the Quick Manual Practical II for the parameter setting method using the GUI software CNVCommCC.

    TDK-Lambda EZA2500W series Quick Manual / Practical(I) 6) External signal connector CN pin assignment The pin assignment of the external signal connector CN is shown below. For details such as electrical specifications, refer to p11 and p13 of the instruction manual.
  • Page 13 TDK-Lambda EZA2500W series Quick Manual / Practical(I) 8) EZA operation mode In EZA, the method of switching the charge / discharge direction is called the operation mode, and there are the following 6 types. Here is an overview. The specific operation method will be explained in the Quick Manual, Practical Part II, so please see that.
  • Page 14 TDK-Lambda EZA2500W series Quick Manual / Practical(I) Operating Characteristic ③ Manual Grid CV with Battery CC mode The basic operation of this mode is the same as the manual grid CV mode described above. When discharging, the maximum current setting value on the battery side, not the grid side, will not be exceeded.
  • Page 15 TDK-Lambda EZA2500W series Quick Manual / Practical(I) ④Automatic Grid CV In this mode, charging is performed when the grid-side voltage exceeds the target voltage. If it falls below, it will discharge. EZA charges and discharges so that the grid-side target voltage is maintained.
  • Page 16 TDK-Lambda EZA2500W series Quick Manual / Practical(I) Battery CC mode operates at a substantially constant current at the battery limit current during charging and discharging. ⑥Automatic Battery CV mode In this mode, charging and discharging are performed to maintain the battery voltage.
  • Page 17: Battery Protection

    TDK-Lambda EZA2500W series Quick Manual / Practical(I) 9) Battery protection EZA has a function on the battery side to prevent overcharge and over discharge of the battery. Overcharge protection and over discharge protection can be set separately. This function is disabled when shipped from the factory. Change the battery setting (BCF) parameter using RS-485 to enable it.
  • Page 18 TDK-Lambda EZA2500W series Quick Manual / Practical(I) 10) Constraint of operating voltage range (HVDC, LVDC) EZA may not be able to control current and voltage depending on the combination of battery side (LVDC) and grid side (HVDC). Therefore, it is necessary to control the system so that the voltage of EZA is within the line shown in the figure below.
