100kW Three-Phase Diesel Generator

The DHY125KSE is a powerful three-phase diesel generator from Hyundai. Suitable for powering three-phase equipment in your business, factory, or multiple estate buildings, this diesel genset has a huge maximum output of 125KVA.

Powerful Hyundai Engine

Powered by a heavy-duty HY6B155L-D21 diesel engine, the DHY125KSE is able to produce a maximum output of 125KVA / 100kW.

Three-Phase Power

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 equipment 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.

Fitted with AVR Alternator

Equipped with an AVR alternator to produce clean energy, the DHY125KSE is suitable for powering sensitive electronic equipment, such as TVs, PCs and laptops, in your factory or business.

ATS Compatible

The DHY125KSE can be started manually by using the key, or connected to an ATS (Automatic Transfer Switch) system, which will automatically turn on the generator when a loss of power to the property is detected. When power returns from the mains, the ATS module will then safely turn your generator off.

This is ideal for those who need to guarantee constant power - for example, if you run servers or have refrigeration units.

Silenced Generator

Housed in a weather-proof 'silenced' canopy, the DHY125KSE produces only 70dB @ 7 metres which makes it a quiet standby generator that won’t interrupt you at home or work.

Power Cut Protection

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.

1500rpm Generator

1500rpm diesel generators are ideal for static installation for daily prime power, as well as for regular standby generator/backup generator use.

1500rpm generators have slower running, water-cooled engines which are less stressed than 3000rpm generators, which make them the best option if you’re going to use your generator as your main power source and will also prolong its lifespan.

Economical Generator

Diesel generators are ideal for backup applications as sometimes petrol can go stale and prevent a generator working. Our diesel generators also run happily on budget-friendly red diesel, without voiding the warranty and making it cost-effective to refuel.

Delivery

Kerbside delivery is included in the price. However, please note that a forklift will be required for unloading.

2 Year Warranty

This 125kVA diesel generator comes with a 2 year Hyundai warranty with full UK parts and service backup for added peace of mind. Read our warranty terms here.

Generator kVA Ratings

All of our generators have a kVA rating that is higher than the kW. This is because we have assumed the appliances you are going to power have a load factor/power factor of 0.8 - therefore the 'assumed' kVA rating of the load would be higher. This is industry standard and it is usually best to scope the right unit based on the kW.
