Sleep Function; Standby Function - IVT DSW 12 V Série Notice D'utilisation

GENERAL NOTES FOR USING AC CONSUMERS ON VOLTAGE CONVERTERS
In general, all AC consumers can be used on a sinus voltage inverter. Observe, however, that for doing so you are always
restricted by the availability of the battery capacity and the output requirements of the individual AC consumers. For a better
assessment of the battery reserve, we recommend to familiarize yourself with some relevant characteristics of AC consumers.
One important factor is the initial current. Most consumers require a significantly higher starting current than indicated on the
type plate of the device. E.g. bulbs require starting current which is up to 8 times higher for approx. 1 second. Refrigerators
and TV systems require starting current which is up to 10 times higher for 1 to 3 seconds. This is why it is necessary when
choosing the voltage converter to ensure that corresponding output capacity is available. Therefore, a voltage converter must
provide a continuous output of 500 W (50 W x 10) to operate a small refrigerator with a continuous output of 50 W. Check the
voltage requirements of the consumers to be connected. Connect only consumers whose voltage specifications and output
correspond with those of the voltage converter. Do not connect defect or damaged consumers.

SLEEP FUNCTION

By using the sleep function the inverter automatically turns off, if the 230 V AC output is not used for more
than 10 minutes. Is this function active, there is no own power consumption of the inverter. To restart the
device it is necessary that the user turns off and on again the main switch (8) of the inverter. This function is
selected by DIP switch 1 (see picture).

STANDBY FUNCTION

To conserve the life of the connected battery, you can activate the standby function on your voltage
converter. For this purpose activate DIP switch 2 on your device (see picture). Now the voltage converter is in
standby mode. This reduces the own power consumption significantly. Now the device checks every whether
load is connected in intervals of 10 seconds. When the voltage converter recognizes a load above standby
level (see technical data), it connects the 230 V AC output and is thus in normal operation again.
SAFETY AND PROTECTION MECHANISMS
Reverse polarity protection
The inverter is protected against reverse polarity. This means that the voltage converter doesn't get damaged if the battery is
connected with wrong polarity.
Overvoltage shutdown
The voltage converter switches off as soon as the input voltage exceeds the given maximum value (1.33 x U
Dynamic deep discharge protection
The voltage converter switches off as soon as the input voltage drops below the set value. This is to protect your battery
against deep discharge. With the remote controls units you can make your own adjustment of the deep discharge protection
individually between 9 V - 12 V on the 12 V version or 18 V - 24 V on the 24 V version. This adjustment is not possible without a
remote control unit. Factory settings of the deep discharge protection for the 12 V versions are 10.5 V and 21 V for the 24 V
versions. The DSW voltage converter series is equipped with a dynamic deep discharge protection. I. e., at high output the
deep discharge protection is automatically reduced to a maximum of 1 V of the set value.
The restart threshold is a permanently set value which cannot be changed.
The value is 12.5 V for the 12 V versions and 25 V for the 24 V versions.
Temperature-activated protective circuit
The voltage converter switches off when the temperature inside the device is too high.
Overload management
The voltage converter switches off when the output or the starting current of the connected devices is too high. Then the
voltage converter tries to restart (power start function). Should the device does not restart after repetitive attempts the
voltage converter is not suitable for the connected consumer. At the DSW-2000 inverters there is no automatically restart if
there has been an overload shut down for five times. A manual reset with the main switch (8) is necessary.
Short-circuit shutdown:
The voltage converter switches off when the output is short-circuited.
Warning:
The inverter automatically restarts, if the reason for shut down is removed.
