Umbreytingar AC Master 24/500 IEC (230 V)

This converter delivers a continuous power output of 500 W at an ambient temperature of 25 °C, and 400 W at 40 °C.

Yes, this is a pure sine wave inverter. It provides 230 V AC power of a quality equivalent to domestic mains, ideal for protecting and running sensitive electronic equipment without hum.

The inverter can handle a peak power of 800 W for 5 seconds. This power reserve is very useful for absorbing current surges when starting devices equipped with electric motors.

Power Saving mode continuously monitors AC output. If the detected load is below 40 W, the inverter reduces its no-load consumption to just 0.17 A (about 4 W), significantly preserving your battery autonomy.

No, unlike higher-power models or the Mass Sine range, this AC Master inverter is not compatible with the MasterBus communication network.

No, it is strongly discouraged to install it in the same compartment or directly above the batteries. Potential corrosive gas emissions (sulfur vapors) from the batteries could damage the internal electronics.

Yes, the converter is supplied as standard with 1.5 metres of pre-assembled DC cable, making it much easier to connect to your 24 V battery bank.

The AC output uses a standard IEC 60320 - C13 (female) connector. An IEC C14 male plug is included in the box to allow you to wire it safely.

No, this model (28020502) is exclusively designed for 24 V systems. If you have a 12 V battery bank, you will need to choose the AC Master 12/500 model.

The converter is very compact and lightweight. It measures 210 x 130 x 60 mm (Height x Width x Depth) and weighs only 1.22 kg, making it easy to fit in tight spaces.

Yes, for safety reasons, the chassis ground terminal must be connected to the vessel’s or vehicle’s central ground point. Additionally, the AC output neutral conductor (N) must be connected to the protective earth (PE/GND).

No, absolutely never. Under no circumstances should the AC output of the inverter be connected to another AC power source (such as shore power or a generator) or in parallel with another inverter, as this may cause irreversible damage not covered by warranty.

The device features comprehensive protections to ensure safe operation: shutdown in case of overheating, protection against overloads and short circuits, as well as automatic cutoff in case of abnormally high or low battery voltage.

The inverter automatically stops if the battery voltage drops to 20.0 V (± 0.5 V) to protect it from destructive deep discharge. It restarts automatically when the voltage rises back to 22.0 V.

The device has an IP23 ingress protection rating, provided it is mounted vertically on a bulkhead with cables oriented downward. Any other mounting position alters this protection level.

Although the device includes an internal 40 A fuse, it is essential to add a properly sized fuse in the positive wiring, positioned as close as possible to the battery to protect your entire DC circuit.

The front panel is equipped with intuitive LED indicators. If the "Sine Wave" LED is lit solid red, this indicates a fault (overheating or overload). If it flashes rapidly in red, this signals a short circuit on your AC network.

The AC Master 24/500 inverter provides a maximum efficiency of at least 91% thanks to its high-frequency technology, which optimizes the use of energy stored in your batteries.

Yes, the device is cooled by an integrated fan. It is recommended to leave at least 10 cm of free space around the converter to ensure adequate airflow and prevent overheating.
