Detailed description

The Mastervolt AC Master 12/2500 HW (UK Outlet) inverter converts 12 V DC to reliable 230/240 V AC power with a pure sine wave output at 50/60 Hz. It is designed for recreational and semi-professional applications, protecting sensitive equipment with its pure sine wave technology. This model includes a UK-style outlet for direct wired connection.

Performance and flexibility

With a continuous output of 2500 W at 40 °C (cos phi 1) and a peak load of < 3000 W (3 seconds), this inverter powers a variety of devices. Its efficiency reaches 88 %. The battery voltage range is 10.5 V to 16.5 V. The energy management system features an automatic energy-saving mode, reducing consumption to less than 1.4 A in standby at 12 V, compared to less than 3.6 A when active. The variable-speed fan ensures quiet operation at low power levels.

Integration and safety

The AC Master 12/2500 can be configured in parallel with 2 to 15 units to increase output power, or in a three-phase setup with up to 3 units. Output voltage and frequency settings, as well as energy-saving and master/slave modes, are configurable via DIP switches. It includes an automatic transfer system that switches between AC power sources. Protections include overheating, overload, short circuits, battery voltage (high/low), and AC overcurrent.

The unit weighs 8 kg and measures 283 x 436 x 128 mm. Its protection rating is IP21 for horizontal wall mounting, and it operates in an ambient temperature range of -20 °C to 60 °C (with derating > 40 °C).

« Technical analysis of the Mastervolt AC Master 12/2500 inverter »

The Mastervolt AC Master 12/2500 stands out as a reliable solution for AC power supply on board, particularly for installations requiring stable power quality. Its ability to generate a pure sine wave is a major asset for protecting sensitive electronic equipment, avoiding the disturbances often encountered with modified sine wave inverters. It is ideal for pleasure boats and professional vehicles where the use of computers, power tools or kitchen appliances is common.

Installation in "hardwired" mode (fixed wiring) is made easier by a compact and lightweight design. The ability to create parallel systems (up to 15 units) or three-phase systems (with 3 units) offers great flexibility to adapt power to evolving or higher needs. The DIP switches allow precise configuration of output parameters and operating modes, including master/slave mode and power saving, requiring careful attention during implementation to ensure optimal system integration. It is essential to respect the IP21 protection rating by installing it in an environment protected from direct moisture.

Frequently Asked Questions

Need help? Contact us

What is the AC Master 12/2500 HW and what is it used for?

The AC Master 12/2500 HW is a Mastervolt power inverter designed to convert 12 V battery DC power into reliable 230/240 V AC at 50/60 Hz. It delivers a pure sine wave output, making it ideal for powering sensitive equipment in recreational and semi-professional applications.

What is the continuous output power of the AC Master 12/2500 HW inverter?

The AC Master 12/2500 HW inverter delivers a continuous output of 2500 W at 40 °C, with a power factor of 1. It can also handle a peak load of less than 3000 W for 3 seconds.

What type of alternating current (AC) is produced by the AC Master 12/2500 HW?

The AC Master 12/2500 HW produces a pure sine wave. This technology ensures stable power supply and protects sensitive electronic equipment from damage.

Does the AC Master 12/2500 HW inverter have an energy-saving mode?

Yes, the AC Master 12/2500 HW inverter is equipped with an automatic energy-saving mode. In this mode, no-load consumption is less than 1.4 A at 12 V, compared to less than 3.6 A in active mode. This mode reduces battery drain when no load is present.

What are the built-in protections in the AC Master 12/2500 HW?

The AC Master 12/2500 HW integrates multiple protections to ensure the safety and durability of the equipment. These include protection against overheating, overload, short circuits, low or high battery voltages, and AC overcurrent (via a circuit breaker).
