Battery charger/Power supply 4921210105H Easy installation - DIN-rail mounting Automatic recovery from overload conditions Switch mode power technology Application The DCP2 can be applied as battery charger or stabilized network component as a universal DC voltage supply. As battery charger parallel operation with other DC consumers is possible. For 10A, 20A and 40A types: OUTPUT VOLTAGE DCP2 as battery charger As battery charger the DCP2 is applied to charge and to maintain the full-charge condition of closed or gastight 24V (12V) Pb batteries. In parallel operation with a battery and other consumers the nominal power for the consumers is given until interruption from the battery, e.g. for the reason of recharging/maintenance. Automatic Restart (hicc-up mode) DCP2 as network component (power supply) As stabilized network component the DCP2 supplies connected consumers with a stabilized DC voltage. Protection The DCP2 is protected against continuous short circuit as well as continuous no-load operation. Further characteristics of the DCP2 are the high efficiency and the high voltage stabilization. For 5A types: OUTPUT VOLTAGE Principle/operation Application as stabilized net unit (supply) The DCP2 supplies a constant output voltage, according to setting, in the range of 23.5-27.5V DC respectively 11.8-13.8V DC (stabilized network component). The output voltage is held constant as long as the load does not exceed the nominal current. A load exceeding the current limitation will automatically reduce the output voltage (see the curves in the next column). Typical current limit for each type is specified under Technical specifications, section Output current. Automatic Restart (hicc-up mode)

Type DCP2 Application as battery charger When charging of a discharged battery is initiated, a high charging current will flow, which is limited and controlled by the DCP2. Voltage will immediately jump to approx. 2.1V per cell (12.6V for 12V types and 25.2V for 24V types). Normally it is recommended from manufacturers of Pb batteries to obtain 2.25V per cell at temperatures up to 30°C, before the battery is fully charged and trickling can start. For a 12V Pb battery this gives a trickle charging voltage of 13.5V (2.25 x 6 cells) and 27V (2.25 x 12 cells) for 24V batteries. According to information...
