The buffered DC power supply of the PLG series uses external lead or gel batteries up to 38 Ah in the event of a power failure on the primary side in order to maintain the 24 V DC supply. When the mains voltage is available, the PLG provides the output voltage UA and charges the battery or receives its charge. The load current is independent of the battery's state of charge. The microprocessor-controlled charging process with an I-U characteristic curve ensures that the battery is charged as gently as possible. The output side is protected by the short-circuit and overload resistance of the output current.
LED displays enable a simple diagnosis of the condition.
We also offer various preassembled battery packs that are ideal for use with the PLG.
