Střídač 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 with a quality equivalent to that of the domestic grid, ideal for protecting and operating sensitive electronic equipment without humming.

The converter 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.

The energy-saving mode continuously monitors the AC output. If the detected load is below 40 W, the inverter reduces its idle consumption to just 0.17 A (approximately 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. Any potential corrosive gas emissions (sulfur vapors) generated by the batteries could damage the internal electronics.

Yes, the converter is supplied as standard with 1.5 meters 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) connection. A standard IEC C14 male plug is included in the box to allow you to wire it safely.

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

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 integrate into 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 neutral conductor (N) of the AC output must be connected to the protective earth (PE/GND).

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

The device features full 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 converter automatically shuts off 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 protection rating, provided it is strictly mounted vertically on a bulkhead with cables facing downward. Mounting in any other position alters this protection level.

Although the device includes an internal 40 A fuse, it is essential to install a properly sized fuse on the positive wiring, placed 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 offers a maximum efficiency of 91 % or higher 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 a free space of at least 10 cm around the converter to ensure adequate airflow and prevent overheating.
