Cameleon buffer power supplies were created on the basis of single-output universal power supplies by adding an additional package to the power station, allowing for direct handling of accumulator batteries. The power supply equipped in such a way practically fulfills the role of a telecommunications power plant or other uninterruptible voltage source (UPS DC), ensuring independent operation of the attached battery.

 

As standard, the power supplies are equipped with light and relay signaling and the so-called overdischarge switch (RGR) protecting the connected batteries against excessive discharge. The temperature probe allows you to adjust the output voltage (buffer voltage) depending on the ambient temperature of the batteries. The use of these systems allows to maintain the proper operating parameters of the connected batteries and extends their service life.

 

Thanks to the use of a special, programmable battery charging current limitation system, the power supply can work with batteries of different capacities, while ensuring the appropriate current and charging time for the batteries used.

• single-phase input voltage 230Vac or 220Vdc;
• optical signaling of correct operation and current limitation;
• relay signaling of correct operation of the power supply;
• separate output and battery connectors;
• possibility of floating operation with temperature compensation of the charging voltage;
• possibility of automatic charging;
• optical indication of charging, battery operation and low battery status;
• protection of accumulator batteries against excessive discharge (RGR);
• battery circuit fuse;
• battery charging current switch;
• floating operation voltage selection switch (V / cell);
• faceplate terminals and mounting method can be selected.
