Description

Central Battery Systems in the TKT66C series offer effective and space-saving solutions for supplying a moderate quantity of luminaires. They are especially suited for mid-sized and large premises where it is desirable to divide the central battery system into multiple independent regions.

The central unit input voltage is 220-240 VAC, except for three phase input models (that end in letter F) the input voltage, of which is 400 VAC between the phases. The output voltage is 220-240 VAC in normal mode and 216 VDC in battery mode. The battery voltage is 216 V, which is achieved by connecting eighteen 12 volt batteries in series.

In addition to the normal emergency lighting functions, Central Battery Systems in the Tapsa Control TKT66C series make it possible to test automatically the condition of the central unit itself and the luminaires connected to it. The testing of luminaires is based on individual addresses and the communication is by means of the power supply cables. Thus, there is no need for any separate data cabling between the luminaires. The luminaires must be addressable, of the Teknoware model ending in K, or they must have a separate address module.

Utilisation of these luminaires also enables the connection of maintained and non-maintained lights to the same circuit and allows local supply monitoring using Teknoware Local Controller, or Intelligent Controller, which can also be used to control the non-maintained emergency lights. These central units have, depending on the model, either 8, 16 or 24 output circuits, which can be set to function as maintained of non-maintained. A maximum of 32 addressable luminaires can be connected to one circuit. Circuits can also be connected in parallel to increase the output power with the following changeover module outputs possible: 8 x 350 VA, 4 x 700 VA or 2 x 1400 VA.
