Technical data

Power supply Alternating voltage 230 V / 50 Hz, single phase
Range approx. 195 V - 265 V / 50 – 60 Hz.
Output current: Charging current max. 20 A,
(Charging current for
arithmetic average, electronically regulated according to
battery II)
the charging characteristic curve IUoU.
Output current: When the battery potential of battery II reaches 14.3 V, a
(Charging current for parallel connection is established with battery I.
battery I)
Compensating current dependent on the charge state of
battery I (starter battery). If the voltage of the battery II
drops below 13.2 V, the parallel circuit is automatically
disconnected.
Output voltage:
Direct voltage 12 V
Charging process: Automatic
Automatic OFF when battery voltage reached 14.4 V, charging
switching: current < 18 A
(Main charging phase)
Automatic Ten hours constant 14.4 V in the case of gel batteries.
switching: Four hours constant 14.4 V in the case of liquid batteries.
(Post charging phase)
Automatic Holding charge, constant at 13.8 V.
switching:
(Holding charge phase)
Switching Tremat isolating relay: 50 A
capacity: Refrigerator relay: 20 A
User relay: 35 A
Temperature The values of the automatic switching refer to a battery
dependent control temperature of 20 °C. When using a temperature sensor at
(optional) the battery II, these values vary as a function of the
battery temperature.
High temperature > Lowering of the threshold values.
Low temperature > higher threshold values.
Application: Parallel operation, buffer operation, general charging
operation
