PERKINS 15kVA Diesel Generator – AP15S

Manufactured by CPS in Yorkshire UK, this 15kVA generator is proudly assembled and built using UK Components such as Perkins engines and deep-sea electronics control systems. The AP15S – 15kVA diesel generator houses a robust and reputable Perkins 403A-15G2 engine and is suitable for a range of power applications such as a standby generator or as prime power generator supplying commercial and industrial equipment and machinery.

These canopied diesel generators are ready for use on arrival and need no extra assembly. Just fill the tank up, connect your cables and press start!

Standby Generator

With a standby power rating of 16.5kVA this 15kVA diesel generator is capable of supporting critical applications as a backup power source when the mains supply fails. By housing the engine inside a weatherproof acoustic silent canopy, it can be installed outdoors with minimized sound disturbance for surrounding neighbours.

All CPS canopied diesel generators are fitted with a long run base fuel tank, which will easily support full load for 8 hours or more, giving you peace of mind that you will have reliable backup power when the mains fails.

As an optional extra they can be fitted with an auxiliary battery charger and engine jacket water heater, so that it is ready for use as a standby generator to protect your building from an outage.

Quality Components

CPS generators only use leading brand components from the main engines and alternators, right through to the wiring terminals and hoses. This gives you the confidence that your generator will have a long service life and be easily supported with spare part availability.

All of the CPS generators listed on our store are powered with UK Perkins engines, which are some of the best engines on the market and have been used across numerous industries worldwide. The generator alternators are all from leading European brands such as Meccalte, Leroy Somer and Stamford.

Leading Brand Generator Control – Deep Sea Electronics UK

Inside the 15kVA diesel generator canopy is a controls and power enclosure which features a Deep Sea Electronics generator controller. These are the best generator controllers on the market and allow you to easily control and monitor all aspects of the engine and alternator performance such as:

  • Electrical information – Output voltage, frequency and load currents.
  • Engine information – Speed, Temperature and Oil pressure
  • Fuel levels, Coolant level and Battery voltage
  • Number of starts and run hours

The controller provides complete protection for the engine and alternator in the case of any issues. It will prevent starting or shutdown the generator and provide alarm notification and information on screen, making it easy to diagnose and rectify any simple issues such as low fuel or oil levels.
