The power supplies meet the requirements of the EN54-4 + A2 standard, thanks to which they can be used as power devices in fire alarm and fire signalization systems, e.g. in control panels of fire protection devices.

The power supplies have an additional packet that allows for direct supervision of rechargeable battery banks. The power supply equipped in such the way practically fulfills a role of a telecom power system or another voltage source (UPS DC) ensuring self-servicing of the connected battery.

In standard, the power supplies are equipped with the LED and relay signalization and in the so-called low voltage disconnect device (LVDD) protecting the connected batteries from excessive discharge. The temperature sensor allows for adjusting the output voltage (floating voltage) depending on the ambient temperature of the batteries. The use of these systems makes it possible to maintain the proper operating parameters of the connected batteries and extends their life.

Thanks to the use of a special, programmable battery charging current limitation circuit, the power supply can cooperate with batteries of various capacities, ensuring at the same time the appropriate current and charging time of the connected batteries.
