Microprocessor-controlled electronics
A microprocessor forms the heart of the inverter. This control center monitors the most important parameters of the electronics, such as the input voltage and frequency. This ensures the constant stability of the output voltage

Continuous output power 300 W - peak output power 600 W
Especially with loads that require a high inrush current, the start does not always run smoothly. For this reason, all DSW inverters are designed to provide twice the continuous output power for a short time

Power start function for consumers with high inrush current
All DSW inverters have a power start function as standard. When the load is switched on, the inrush current can briefly reach 5 to 10 times the specified rated current. The power start function attempts to compensate for this phenomenon by carrying out up to 5 start attempts with maximum output power in quick succession

E-approval: suitable for fixed installation in vehicles
The Digital Sinus Inverters meet the legal requirements of the ECE regulation and thus have the E-certification. They are suitable for permanent installation in all vehicles with road approval, whether passenger cars, commercial vehicles or other vehicles with 12 V on-board voltage

Galvanic isolation of input and output stage
Thanks to galvanic isolation, there is no electrically conductive connection between the input and output circuits. Therefore, no additional personal protection device (RCD or DI switch) is required even for commercial use when only one 230 V consumer is connected

Extensive protection functions
IVT inverters provide protection against reverse polarity and overvoltage at the input and against short circuit and overload at the output. In case of overtemperature, there is an automatic shutdown

Dynamic deep discharge protection
On the one hand, the dynamic deep discharge protection ensures that the battery is protected against deep discharge, and on the other hand, it also allows loads with a high inrush current to be switched on, as the switch-off threshold is lowered for a short time. With the optional available remote controls FB-04, FB-05 as well as the Webbox-LCD there is the additional possibility to adjust the deep discharge protection individually.

A voltage between 9 V and 12 V (for 12 V models) or 18 V and 24 V (for 24 V models) can be selected. When the specified limit is reached, the inverter first indicates this by flashing the input LED. The load output of the inverter then switches off automatically. Only when the battery has reached the necessary restart voltage, the load output becomes active again.

Switchable power saving functions:Standby, Sleep
Standby function: If the inverter is not needed all the time, the switchable standby function makes it possible to reduce the inverter's own power consumption by approx. 90 %. To do this, simply press DIP switch 2 (see picture) directly on the device. The device now checks every 10 seconds whether a load is present. If the inverter detects a load above the standby level,it switches the 230 V AC output on and is thus back in normal operating mode.

Sleep function:All inverters of the DSW series are additionally equipped with a sleep function.If the load output is not used for more than 10 minutes, the inverter switches off automatically and no longer draws current.By switching off and on the main switch directly at the device or at places difficult to access with the help of the remote switch FS-01, FS-02 the restarting takes place.The sleep function can be activated or deactivated with the DIP switch 1 (see picture) directly at the device. This prevents unnecessary discharge of the battery.

230 V protective contact socket
Standard version suitable for plug type: F, C All Digital Sine Wave Inverters are equipped as standard with a 230 V protective contact socket, suitable for the plug types C (Europlug) and F (Schuko plug) commonly used in Germany and most European countries

Standard 5 V USB connection
All DSW inverters have a 5 V USB port for powering suitable external devices such as cell phones, tablets, cameras or navigation devices

Power and temperature controlled fan
The power and temperature controlled fan minimizes the noise of the inverter by only switching it on when needed

Lightweight and powerful
DSW inverters are characterized by their low weight. Conventional inverters are often equipped with large ring transformers. As a result, they are heavy and unwieldy. In contrast, the microprocessor-controlled IVT inverters work digitally thanks to innovative technology: large, heavy components are eliminated and replaced by small and powerful components

Solid metal housing
The valuable inner workings of the inverter are protected by a solid and stable metal housing. Thanks to the mounting rail, the inverter can be stably fixed anywhere

Remote switch on/off: Available as accessory
Inverters are often installed in places that are difficult to access during later use. The FS-01 (surface-mounted version) and FS-02 (flush-mounted version) remote switches can be used to switch all DSW inverters on and off at a suitable location. The remote switch replaces the main switch on the inverter

Remote control: Individual control and monitoring of up to 4 devices
With the optional available remote controls FB-04 (wired), FB-05 (radio base) as well as the Webbox-LCD (operation in an existing computer network) there is the possibility to adjust the deep discharge protection individually. A voltage between 9 V and 12 V can be selected for the 12 V models, and a voltage between 18 V and 24 V for the 24 V models

The remote controls as well as the webbox LCD also offer the advantage of individually controlling and monitoring up to 4 devices (inverters of the IVT DSW series, solar controllers of the MPPTplus+ series).

Suitable connection cable sets
For a safe and trouble-free operation of the DSW inverters we recommend the use of the original IVT connection cables. These are exactly matched to the respective inverter in terms of conductor cross-section and cable length. The high-quality workmanship of our connection cables guarantees a particularly long service life even under high loads

The cable set is already pre-assembled with suitable ring lugs and wire end ferrules for connection to the battery and the inverter. All original IVT connection cables are supplied including fuse holder and 200 A fuse.

Note on safety for the commercial sector: If a multiple socket is connected and several 230 V consumers are used at the same time, the professional associations stipulate that each additional consumer must be protected with a separate RCD or DI circuit breaker.
