Pramac GPW 45 Y diesel generator – BASIC PLUS 400V

The Pramac GPW 45 Y 400V is a high-performance model from Pramac’s professional diesel range, which is designed for applications requiring a higher power reserve under three-phase loads, stable operation in intensive mode and a generator suitable for continuous daily operation. The model delivers a maximum power output of 38.0 kW and a rated power output of 34.4 kW, and is therefore well suited to production facilities, construction sites, service and technical centres, agricultural businesses, plant rooms, warehouse complexes and the emergency power supply for commercial premises where a reliable three-phase power source is essential.

This model is powered by a Yanmar 4TNV98CT-IPGE diesel engine with a displacement of 3,319 cm³. It is a 4-cylinder in-line engine with a turbocharger that complies with the Stage V emissions standard. This version also features an electronic speed governor, which is a significant advantage for a generator of this class, as it allows stable operating parameters to be maintained more accurately under varying loads. The liquid cooling system ensures reliable thermal performance during long-term operation, and the engine configuration is well suited to applications where the generator is expected not just to start once, but to provide reliable and predictable operation.

Start-up is via an electric starter powered by the 12 V battery system, making the model suitable for both emergency scenarios and day-to-day operation. This configuration enables the generator to be brought into operating mode quickly, which is particularly important at sites where even a brief power cut can disrupt the operation of technical systems, pumps, ventilation systems, automated controls or other equipment.

The model also impresses in terms of its electrical specifications. The generator operates at a voltage of 400/230 V, a frequency of 50 Hz and has three phases. It is fitted with a brushless Mecc Alte ECP32 2S4 C generator with insulation class H and protection rating IP23. The maximum current is 69 A and the rated current is 62 A, meaning the generator is suitable for supplying a higher three-phase load than the newer models in the series. This enables it to be used for equipment in workshops, on building sites, in service areas or in commercial premises with mixed power consumption.

Another strength of the Pramac GPW 45 Y 400V is its combination of power and reasonable fuel autonomy. The documentation specifies a fuel consumption of 7.43 l/h at 75 per cent load and 10.55 l/h at 100 per cent load. With an internal 80-litre tank, this results in an operating time of 10.77 hours at 75 per cent load. Based on the fuel consumption at full load, the approximate operating time is around 7.58 hours. This figure is well suited to work shifts, emergency power supply and scenarios where it is important to maintain a balance between performance and fuel costs.

The PDF lists the available control variants – ACP and MPP – separately. The ACP version supports AMF(Automatic Mains Failure), i.e. automatic start-up in the event of a mains failure, as well as full monitoring and protection of the generator. The MPP version enables the system to be used in parallel configurations. This makes the model more flexible in terms of integration into real-world emergency or main power supply systems. The file also specifically notes that the socket panel is optional and that the socket set is specified at the time of ordering, so that the connection configuration can be adapted to the specific requirements of the site. :contentReference[oaicite:3]{index=3}

In terms of design, the model is fitted with a soundproof and weatherproof enclosure, which helps to reduce noise whilst protecting the generator from external influences. The design includes large side doors for convenient maintenance access, vibration-damping supports, a robust steel base, a crane lifting eye and a reliable top lifting lug. This makes the generator more practical for transport, installation and regular maintenance under real operating conditions.

The model measures 2200 × 1020 × 1423 mm and weighs 987 kg. According to the documentation, the noise level is 61/90 dB, i.e. 61 dB at a distance of 7 m and 90 dB LwA. For a diesel generator of this class, this is a good figure, enabling the model to be used not only on rough industrial sites but also in technical and commercial environments where acoustic comfort is also a consideration.

The Pramac GPW 45 Y 400V is a good choice for anyone looking for a powerful, modern and well-balanced diesel generator with a Stage V Yanmar engine, electronic speed control, a reliable three-phase unit, good running time and the ability to flexibly adapt the control configuration to specific tasks.
