<strong>Power</strong> supplies to cooperate with batteries<br />
EL25, EL50<br />
The power supplies EL25 and EL50 are a regulated source <strong>of</strong> DC voltage, power <strong>of</strong> 25W and 50W, respectively. They are constant<br />
frequency switching power supplies. They are devoted to cooperate with a battery bank connected as a buffer.<br />
FUNCTIONS OF THE DEVICE<br />
• UI output characteristic<br />
• protection against overload or short circuit<br />
• visual indication <strong>of</strong> presence <strong>of</strong> output voltage<br />
• indication <strong>of</strong> battery mode<br />
• indication <strong>of</strong> low battery<br />
• possibility to cut <strong>of</strong>f <strong>the</strong> load from output voltage<br />
CHARACTERISTIC FEATURES<br />
• charging current limitation<br />
• protection <strong>of</strong> <strong>the</strong> battery bank against too deep discharge<br />
• possibility to switch <strong>the</strong> unit on from <strong>the</strong> battery – “cold start”<br />
AGM batteries<br />
Maintenance free batteries are used to cooperate with battery backup power supplies. We <strong>of</strong>fer maintenance free batteries <strong>of</strong> <strong>the</strong><br />
following brands: Panasonic, Europower, SSB, Acumax and Alarmtec. Because <strong>of</strong> gas recombination <strong>the</strong>re is no need to replace<br />
electrolyte, and batteries can be applied in rooms without dedicated forced ventilation .<br />
FEATURES<br />
• AGM technology<br />
• design life up to 15 years<br />
• voltage <strong>of</strong> single monoblocks: 2V, 6V i 12V<br />
• range <strong>of</strong> capacity from 0.8 to 300Ah<br />
• small internal resistance<br />
• operation possible in arbitrary orientation<br />
• broad range <strong>of</strong> working temperature<br />
• DIN rail clip<br />
• <strong>the</strong>oretical MTBF <strong>of</strong> 1.5 million hours (according to Telcordia SR-<br />
332, taking into account electrical stress <strong>of</strong> single elements)<br />
