Pramac GBW 10 Y 400V diesel generator

ThePramac GBW10Y-400 is a three-phase diesel generator housed in a soundproof enclosure, designed to provide reliable backup or primary power for facilities, technical rooms, workshops, small production areas, commercial applications and engineering equipment. The model combines an economical Yanmar diesel engine, good autonomy, convenient electric start-up and stable operation in stationary mode.

The generator operates at 400 V in a 3-phase configuration. The PRP rated power is 6.72 kW, and the LTP standby power is 7.14 kW. This configuration is well suited for backup power supply to buildings, engineering systems, pumping equipment, lighting, automation and other loads requiring a stable 3-phase power supply.

The Pramac GBW10Y-400 is equipped with a Yanmar 3TNV80F-NGPGE diesel engine with a displacement of 1,267 cm³. This is a 3-cylinder in-line engine with water cooling, naturally aspirated air intake and a mechanical speed governor. Electric start ensures convenient commissioning of the generator, whilst compliance with Stage V confirms the model’s modern environmental standards.

The 51-litre fuel tank ensures long-lasting autonomous operation. The technical specifications for the model explicitly state a fuel consumption of 1.92 l/h at 75% PRP and 2.83 l/h at 100% PRP. Operating time is up to 26.56 hours at 75% load and up to 18.02 hours at 100% load, making the generator suitable for prolonged standby operation without frequent refuelling.

The Linz E1S13SB alternator operates in a 3-phase configuration and features a brush design. The documentation for this series specifies compound voltage regulation and a voltage accuracy of ±4% from no-load to full load at a stable rotational speed. It also features low harmonic distortion, allowing for the connection of various types of loads, including non-linear ones.

The model is housed in a soundproof enclosure, which reduces noise levels thanks to special insulation materials and an effective internal silencer. The noise level is 64/93 dB, making the generator suitable for use near buildings, technical areas and sites where a moderate acoustic background is important.

The generator can be equipped with an MCP manual control panel or an ACP automatic control panel. The manual control panel includes measuring instruments, protective devices, a start/stop key switch, an emergency stop, and a standard set of sockets. The ACP automatic panel operates with the AC03 controller, supporting automatic mode, test mode, remote control and connection to an automatic transfer switch system.

With dimensions of 1645×870×1072 mm and a dry weight of 420 kg, the Pramac GBW10Y-400 is a good choice for users who need a compact, economical and reliable diesel generator for backup power supply with long running time, sound insulation and the ability to operate via an automatic backup system.
