Page 3: Introduction
1.1.2 Terms of Use • The BAC25A shall be used only if it is in good technical condition. Its use shall be in accordance to local safety and industrial regulations. Adequate precautions must be taken to avoid any risks related to high voltages associated with this equipment and nearby objects. -
Page 4: Orderly Practices And Procedures
Do not operate the BAC25A if explosive gas or vapors are present. • When setting up the BAC25A, make sure that the air slots of the test set remain unobstructed. • Removing the BAC25A protective casing will void the warranty. Any work inside the instrument without prior authorization from DV Power will also void the warranty. -

(e.g. L1-L2; A-B). However, the voltage must not exceed 264 V AC. Please refer to the “Technical Data” section. • The BAC25A should be positioned in such a way that it is possible to disconnect it from the power supply safely at any moment. WARNING / AVERTISSEMENT This is a class A product. -
Page 6: Intended Use
The Battery charger Unit BAC25A is a stand-alone instrument designed for charging primarily Lead-Acid and Ni-Cd batteries. BAC25A is intended to support the main charger in order to charge battery much faster or to quickly recharge a battery following a discharge test. It is used for charging batteries that serve as backup power supply in: •... -

Manual BAC25A 2 Description 2.1 Front Panel Components 1. Display Displays the settings during the device charging mode selection as well as the measured values during and after charging operation. 2. Keyboard Used to control the device. • UP/DOWN buttons are used to navigate through the active menu and to set the charging parameters. - Page 8 The USB PC interface enables firmware loading. A USB cable is provided as an accessory. 6. Alarm Overvoltage Alarm overvoltage channel is used for connecting the BAC25A with an external ALARM buzzer. If unexpected overvoltage occurs, the external alarm will be activated.

25 A. The BAC25A sets automatically the value of Charge U and Charge I parameters depending on the battery voltage being measured. The Charge I current is set as maximum respecting the battery voltage level. - Page 13 Manual BAC25A Charge U parameter will be set on the value approximately 2% higher than the battery voltage being measured. The automatically set values are not obligatory for the charging and can be changed by the user. NOTE: In case of a mains power supply interruption, the charging will be postponed until the supply is restored.

Page 14: Limits Menu
Boost I. Boost current represents the maximum current (current limit) value at which the BAC25A will boost (equalize) the battery. The BAC25A sets automatically the value of Boost U and Float U parameters depending on the battery voltage being measured. If the device is / remains connected to the battery charged in the previous test, same values of Boost U and Float U parameters as in the previous test will be set. -
Page 15: Set Menu
The charging process will stop automatically if any of the following parameters reaches its pre-set value: STOP U, STOP I and STOP T (Figure 3-9). However, when Boost T parameter is reached in UU mode, the BAC25A will switch to Float charging without interrupting the test. Figure 3-9: STOP messages The ENTER button is used to confirm limit values after the parameters are enabled and set. - Page 16 Manual BAC25A Figure 3-10: The Settings menu The UP and DOWN buttons are used for navigation and ENTER for entering the chosen submenu. Alarm values are the first parameters to be set. After entering the SET ALARM submenu, the instrument switches to the following screen:...
