Hyundai DHY125KSE 125kVA / 50Hz Three Phase Diesel Generator

The DHY125KSE is a three phase 1500rpm diesel generator from Hyundai which is designed to provide affordable and reliable standby power to your premises.

Powered by a Hyundai HY6B135Z-D2 diesel engine, the DHY125KSE produces a maximum output of 125kVA. This is more than enough output to power your family home or keep your business operating during a power cut. This generator is equipped with an AVR alternator which produces a clean and stable power supply, making it perfectly safe to use with sensitive electronic appliances. Any TVs, PCs, laptops, chargers and more in your home or office will not be damaged by this generator.

The huge power output of this generator means that it can easily power a family home with even the most demanding requirements. Estate owners will also benefit from this powerful generator if one large or several smaller buildings need power at the same time.

Power cuts cost UK businesses millions of pounds every year and a standby generator such as this is designed to protect your revenue. If your business relies on a server room, online sales, refrigeration or freezers, then regular or extended power cuts can be disastrous for your finances.

To guarantee the generator always ready to protect you from a power cut around the clock, you can configure it to work with an Automatic Transfer Switch (ATS). An ATS system will automatically detect a loss of power from the mains, turn on your generator and switch over to that as the main source of power, and then turn the generator off and switch back to mains when it detects the power has returned. This peace of mind is priceless, especially when even a short downtime in power could have a big impact on your finances. The ATS package is sold separately.

All Hyundai 1500rpm diesel generators also have the optional extra of remote monitoring and control. Using Ethernet or GSM, you can start and stop your generator from anywhere in the world via a PC, laptop, smartphone or tablet. The benefit of having a 1500rpm generator for standby power, rather than a 3000rpm generator, is that a 1500rpm generator will have a much longer lifespan is properly serviced due to the lower revs. Housed in a sound attenuated canopy, this generator keeps noise levels to a minimum to avoid disturbance and it’s also protected from the worst of the British weather.

All Hyundai 1500rpm diesel generator sound proof canopies undergo an anti-corrosion painting process called electrophoretic painting. This process ensures all areas of the canopy have an evenly applied thickness of paint, ensuring maximum corrosion protection.

3 Phase 400/230v generators are generally manufactured to power 400 volt 3 Phase equipment. Even though you can run a small amount of 230v on a solo basis from them, this is not their intended purpose and it can be difficult to 'balance' the phases and stop the generator from tripping out. In order to run 230v output only, and reach the generator's output capacity you will need to accurately 'balance' the loads on each phase (the amount you are drawing from each phase of electricity). You can read more about phase imbalance, and the pitfalls of running 230v from a 400v generator in our article here. If you are unsure whether this is the right generator for your application, we advise you to speak to a qualified electrician/generator installer or speak to us for advice.
