1.3. General description
TKT65XXB central battery unit is based on the Teknoware TKT series product family. This family is
designed and manufactured according to the EN 50171 standard.
In normal situations, the unit works from the 230 VAC mains supply, by maintaining the battery
charging level, and by feeding a voltage of 230 VAC, to the maintained output circuits. When the mains
voltage fails, or it drops below 180 V, the unit changes to battery use. This connects a voltage of 220
VDC to the non-maintained circuits, and the voltage feed to the maintained circuits changes from 230
VAC to 220 VDC. The battery feed works as long as the mains voltage remains unavailable, or the
battery voltage is lowered to the deep discharge limit (173 V).
The batteries (18 pcs) for the unit always require a separate battery cabinet.
All the functions related to the use of the unit can be performed from the control panel that also
includes display LEDs to indicate the operation status. The panel functions are presented in Appendix
1.
