Digital Sine Wave Inverter IVT DSW-300, 24 V, 300 W

Absolutely self-sufficient thanks to real sine wave AC voltage Note on safety for the commercial sector:

Features & Functions

Real sine wave alternating voltage 230 V/50 Hz

The digital control converts a 12 V or 24 V direct voltage into a pure sine wave output voltage of 230 V/50 Hz

Microprocessor-controlled electronics

A microprocessor forms the heart of the inverter. This control centre monitors the most important parameters of the of the electronic system, such as the input voltage and frequency. This ensures constant stability of the output voltage.

Continuous power 300 W – Peak output power 600 W

Especially with loads that require a high inrush current, the start-up does not always run smoothly. For this reason, all DSW inverters are designed to provide twice the continuous output power for a short time. Please note: To determine the appropriate inverter, you need to know your total power requirement. This is the sum of the power (W or VA) of each individual consumer. We recommend that you allow for a power reserve of 30 - 40 % upwards. To the overview "How to find your inverter" >

Powerstart function for loads with high inrush current

All DSW inverters have a powerstart function as standard. Inrush current When the load is switched on, the inrush current can briefly reach 5 to 10 times the specified nominal current. The powerstart function attempts to compensate for this phenomenon by making up to 5 start attempts with maximum output power.

E-certification: Suitable for permanent installation in vehicles

The digital sine wave inverters meet the legal requirements of the ECE regulations and therefore have the E-certification. They are suitable for permanent installation in all vehicles with road approval, such as passenger cars, utility vehicles or other vehicles with 24 V on-board voltage.

Galvanic isolation of the input and output stage

Galvanic isolation (see fig. above) Thanks to galvanic isolation, there is no electrical conductive connection between the input and output circuit. Therefore, no additional personal protection device ( RCD or DI circuit breaker) is required even for commercial use when only one 230 V consumer is connected. Please note: If a multiple socket outlet is connected and several 230 V consumers are used at the same time, the German trade associations stipulate that each additional consumer must be protected with a separate RCD or DI circuit breaker. Please obtain information from your trade association or on the Internet at: www.dguv.de

Extensive protection functions

IVT inverters provide protection against reverse polarity and overvoltage at the input as well as against short circuit and overload at the output. In case of overheating, the inverter shuts down automatically.

Dynamic deep discharge protection

On the one hand, the dynamic deep discharge protection ensures that the battery is protected against deep discharge; on the other hand, it also allows loads with a high inrush current, as the cut-off threshold is lowered for a short time. With the optionally available FB-04 remote control and the Webbox-LCD , it is also possible 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. If the set limit value is reached, the inverter first indicates this by flashing the input LED. The load output of the inverter then switches off automatically. The load output only becomes active again when the battery has reached the necessary restart voltage.

Selectable power-saving functions: Standby, Sleep

Standby function If the inverter is not needed constantly, the selectable standby function makes it possible to reduce the inverter's own power consumption by approx. 90 %. For this purpose, only DIP switch 2 (see picture) must be switched on directly on the device. The device now checks approx. every 10 seconds, whether a load is connected. If the inverter detects a load above the standby level, it switches on the 230 V AC output and is thus in the normal operating mode again. Sleep function All inverters of the DSW series are additionally equipped with a sleep function. If the power output is not used for more than 10 minutes, the inverter switches off automatically and no longer draws current. The device is switched on again by switching it off and on again directly at the device or using the remote switch FS-01 or FS-02 when it is in a location that is difficult to access. The sleep function can be activated or deactivated directly at the device using DIP-switch 1 (see picture). This prevents unnecessary discharging of the battery.

230 V grounding-type socket – Country-specific customisation on request

Standard version suitable for plug type: F, C All Digital Sine Wave Inverters are equipped with a 230 V grounding-type socket as standard, suitable for the plug types C (Europlug ® ) and F (Schuko plug ® ) commonly used in Germany and most European countries. Country-specific output socket United Kingdom All DSW inverters are available on request at no extra cost with the socket suitable for plug type G (United Kingdom). Delivery request DSW-300, 24 V, plug type G > Country-specific output socket France, Eastern European countries Furthermore, all DSW inverters are available on request without surcharge with the socket suitable for plug type E, C (France, many Eastern European countries).

5 V USB socket as standard

All DSW inverters are equipped with a 5 V USB socket for the power supply of suitable external devices such as mobile phones, tablets, cameras or navigation devices.

Temperature- and power-controlled fan

The power- and temperature-controlled fan minimises the noise of the inverter by only being switched on when required.

Lightweight and powerful

DSW inverters set themselves apart through their low weight. Conventional inverters are often equipped with large ring transformers. As a result, they are heavy and bulky. In contrast, the microprocessor-controlled IVT inverters work digitally thanks to innovative technology: large, heavy components are omitted and replaced with small and powerful components.

Solid metal housing

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

Remote switch on/off: Available as accessory
