ThePramac GPW 45 Y - BAU 400V is a three-phase diesel generator designed for sites requiring a stable power supply, reliable performance under load and a good runtime without unnecessary operational complexity. The model delivers 38.0 kW of maximum power and 34.4 kW of rated power, making it well-suited for construction sites, industrial areas, technical facilities, service centres, farms, warehouses and backup power for commercial premises where a more substantial reserve capacity for three-phase loads is required.
The generator’s power unit is a Yanmar 4TNV98CT-IPGE Stage V engine with a displacement of 3319 cm³. This is a 4-cylinder in-line naturally aspirated diesel engine, operating at 1500 rpm and featuring an electronic speed governor. For a generator of this class, this configuration is a significant advantage, as it helps to maintain stable parameters more accurately under variable loads. Liquid cooling ensures a reliable temperature regime during prolonged operation, and the engine design itself is well-suited for daily professional use. :contentReference[oaicite:6]{index=6}
The model is equipped with an electric start powered by a 12 V battery system, making it convenient to start the generator both in standby mode and during regular operation on site. This setup is well-suited to technical and commercial scenarios where, following a loss of mains power, electricity supply needs to be restored quickly without requiring additional action from staff. :contentReference[oaicite:7]{index=7}
The electrical components of the model are also well-balanced for the professional sector. The generator operates at 400/230 V, 50 Hz and has 3 phases. It uses a Mecc Alte ECP32 2S4 C brushless alternator with insulation class H and protection rating IP23. The maximum current is 69 A, the rated current is 62 A, and the circuit breaker is rated at 63 A. This allows the model to be used with confidence for three-phase and single-phase equipment, pumps, ventilation, lighting, service machinery and other loads requiring a stable power supply. :contentReference[oaicite:8]{index=8}
In terms of autonomy, the Pramac GPW 45 Y - BAU 400V looks very practical. At 75% load, fuel consumption is 7.43 l/h, and at 100% load — 10.55 l/h. For the 80-litre internal tank, the documentation specifies 10.77 hours of operation at 75% load. If based on full load, the approximate operating time is around 7.58 hours. For a model of this class, this is a good figure, allowing the generator to be used both for backup power and for longer operating cycles without the constant need for refuelling. :contentReference[oaicite:9]{index=9}
The documentation for this model specifically lists the available ACP and MPP panels. The ACP supports automatic operation in the event of a mains failure, whilst the MPP is designed for more complex setups involving parallel operation. It is also noted that the socket panel is optional, and the socket set is specified at the time of ordering. This means that the model can be flexibly adapted to a specific site and the required method of load connection. :contentReference[oaicite:10]{index=10}
The generator is housed in a soundproof and weatherproof enclosure, which helps to reduce noise and protects the unit from external influences. The design features large side doors, anti-vibration mounts, a sturdy steel base, a crane lifting point and an upper lifting bridge. This makes the generator more practical for transport, installation and maintenance in real-world operating conditions. The model measures 2200×1020×1423 mm and weighs 987 kg. The noise level for the canopy version is 61/90 dB, which is a good figure for a generator in this power class. :contentReference[oaicite:11]{index=11}
The Pramac GPW 45 Y - BAU 400V is a robust solution for those who need a modern diesel generator with a Yanmar Stage V engine, electronic speed control, good runtime and a reliable three-phase unit. If there is a separate slide for the BAU version detailing additional equipment, this can be incorporated into the description as specific configuration benefits without mixing them with the basic technical specifications.
