5 Target group for this manual

The electrical installation (chapter "Connecting the device" on page 16) is intended for professionals who are familiar with the applicable regulations of the country in which the equipment is to be installed and/or used.

All other chapters are intended for the users.

6 Intended use

WARNING!

Never use the device on vehicles where the positive terminal of the battery is connected to the chassis.

The devices with integrated battery charger convert direct current into a 230–240 V AC supply of 50 Hz or 60 Hz:

• 12 V==: DSP1212C, DSP2012C
• 24 V---: DSP1224C, DSP2024C

Additionally the devices can charge the following batteries:

• Lead automotive batteries
• Lead gel batteries
• Maintenance-free batteries
  • Absorbed glass mat (AGM) batteries
• Lithium ion batteries

Never use the devices to charge other battery types (such as NiCd or NiMH).

WARNING! Danger of explosions

Do not charge batteries with a cell short circuit. The oxyhydrogen they produce can cause explosions.

Do not charge nickel cadmium and non-rechargeable batteries with the charger. The cases of these batteries can burst explosively.

7 Technical description

The devices can be operated wherever a DC connection is available:

• 12 V==: DSP1212C, DSP2012C
• 24 V---: DSP1224C, DSP2024C

The device can be used as follows:

• As a sine wave inverter: the device produces a pure 230 V output voltage
• As a battery charger (4-stage charging characteristic)
• Power sharing: the device powers a connected load with 230 V and simultaneously charges a battery
• Generator function (mains voltage function): the device supports a 230 V mains voltage by supplementing it with energy from a battery (common power source)

The light-weight and compact construction of this device allows for easy installation in mobile homes, commercial vehicles or motor and sailing yachts.

The output voltage corresponds to the household voltage from the socket (pure sine wave, THD <3%).

Please observe the values for constant output power and peak output power as indicated in chapter "Technical data" on page 29. Never connect devices that have a higher power requirement.

NOTE

Note when connecting devices with an electrical drive (such as power drills and refrigerators), that they often require more power than is indicated on the type plate.

The priority circuit reduces the load on a connected battery by switching the device always to mains operation if AC power grid is connected. The device ensures that a connected load is supplied with voltage:

• In case the AC grid power breaks down or is unstable
• In case the AC grid power does not suffice to supply the connected consumers

The device has various protective mechanisms.

• Overvoltage shutdown: The device shuts itself off when the voltage of the connected DC source exceeds the cut-off value. It restarts when the voltage returns to the restart value.
• Undervoltage shutdown: The device shuts itself off when the voltage of the connected DC source sinks below the cut-off value. It restarts when the voltage rises to the restart value.
• Excess temperature shutdown: The device switches off when the temperature inside the device or the temperature on the cooling element exceeds a cut-off value. It restarts when the temperature falls to the restart value.
• Overloading and short circuit shutdown: The LED on the device indicates an operating fault when an excess load is connected or a short circuit has occurred.

NOTE

The individual values are found in the chapter "Technical data" on page 29.

The device is operated in the following network configuration:

• TN network (fig. 19):

The neutral conductor of the AC output is grounded. A safety switch (RCD) must be installed at the device's AC output.

The softstart function allows the connection of loads with high starting current.

The device can be easily controlled using the DSP-EM.

7.4 Description of functions

The device supports the functions described below.

Power sharing function

If the load from the connected consumer devices and the battery charging current is higher than the connected 230 V power source, the fuse of the power source would normally blow. In power sharing mode, the device reduces the battery charging current and thus increases the power available for connected consumers.

The power sharing level (current at the 230 V input) can be configured using the DSP-EM. If must be adapted to the fuse of the power source. For example, if it has a 10 A fuse, the power sharing level must also be 10 A.

Example (values for illustration purpose only):

AC OUTPUT 8 A 10 A 2 A 12/24 V AC INPUT 230 V

NOTE

Keep in mind that the device only measures the current which flows through the device. If you connect more consumers in parallel, e. g.a refrigerator or an separate charger, this additional load may trip the fuse. In this case, set the power sharing level value below the fuse's value accordingly.

Generator function (external mains power supply)

NOTICE!

Observe the standards that apply in your country to the generator function.

If the load current is greater than the fuse of the connected 230 V power source, the fuse would normally blow. The generator function enables the device to provide additional power, which it takes from the battery.

If the required power falls below the power sharing level, the device recharges the battery.

In generator mode, the 230 V power source and the battery act as a common power source. While doing so, the battery is discharged.

The generator mode can manually be shut off via DSP-EM to ensure that the battery will not be discharged.

If the battery's voltage or capacity does not suffice to support the grid the device is disconnected from the grid and the inverter tries to work in isolated operation.

Example (values for illustration purpose only):

AC OUTPUT 7A 4A 3A 12/24V AC INPUT 230 V

Battery charging function

NOTE

If a battery sensor (accessory) is connected, the device adjusts the voltage according to the measured values.

For this purpose the battery sensor has to be configured with DSP-EM.

The battery is charging with IUOU characteristics (fig. 17).

1: I phase (bulk)

At the beginning of the charging process, the flat battery is charged with a constant current (100 % charge current) until the battery voltage reaches the charging end voltage. The charging current decreases when the battery has reached this charging level.

2: U0 phase (absorption)

Now the two-stage absorption charging process (U0-Phase) begins, where the charge voltage and duration depend on the size and type of the battery. The voltage remains constant until the minimum charging current (6 % of the set current) or the maximum charging time (10 hours) is reached.

3: U Phase (floating)

The U phase serves to maintain the battery capacity (100 %).

If DC loads are connected, they are powered by the device. Only if the power required exceeds the capacity of the device is this surplus power provided by the battery. The battery is then discharged until the device re-enters the I phase and charges the battery.

4: 12-day conditioning

Every 12 days, the battery charger switches back to phase 3 for 85 min in order to revive the battery. This prevents any fatigue symptoms such as sulphation.

• Never use the device on vehicles where the positive terminal of the battery is connected to the chassis.

• If you do not fit a fuse to the positive cable, the cables can overload, which might result in a fire.

• When installed in vehicles or boats, the device must be connected to the chassis or earth.

• When setting up a socket distribution circuit (mains setup), comply with the applicable regulations.
• Only use copper cables.
• Keep the cables for the DC connection as short as possible (<1 m).

- Keep to the specified cable cross section and fit a cable fuse (fig. 8 1, page 1) as close to the battery as possible on the positive cable (see the table).

Device	Required cable cross section	Cable fuse
DSP1212C 25 mm ^2 >200 A

	Input voltage too low The battery needs recharging.Check the cables and connections.
2 s lit, short interruption	Overheating Switch off the device and the consumer.Wait 5 to 10 minutes and switch the device on again without any electric consumers.Reduce the load and make sure the device has better ventilation. Then switch the consumer back on.
	Excessive load Switch off the device and remove the consumer.Then switch the device back on without the consumer. If no excessive load is now shown, then there is a short circuit in the consumer or the total load was higher than the power specified on the data sheet.Check the cables and connections.Press in the AC breaker in the device by hand.
Off	Other fault	Contact the service.
