Q&A
Powered by a water cooled Perkins 1104D-E44TAG2 diesel engine, and made in Britain by leading manufactures Stephill Generators, this unit is robust and world class in terms of reliability and performance. The engine itself runs at a low 1500 rpm to extend the engine life and increase reliability, while running at high temperatures for impressive performance and a power output of up to 117kVA / 93.7KW. Low oil pressure shutdown is designed into famously reliable Perkins diesel engine.
Designed for environments where an inferior generator would quickly become a nuisance, Stephill’s advanced Zintec steel acoustic cabinets makes for a low noise output of 65dB(A) @ 7Metres 90LWA. This generator set is fitted with brushless AVR controlled alternators-voltage regulation +/- 1.0% making for a minimal maintenance. Large access doors make for greater ease of maintenance. The long run 510 litre bunded tank provides up to 25 hours running at 75% (three way valve for connection to bowser is included in the standard installation). Safety features like an emergency stop button and battery isolator switch comes as standard for enhanced site security.
Socket Arrangement
Every BS4343 socket is individually overload protected and there is a facility for a hard wire connection (MCB Overload Protection Switchable Variable RCD Protection):
- 1 x 16A 230V Socket
- 2 x 32A 230V Sockets
- 1 x 32A 400V Socket
- 1 x 63A 400V Socket
- 1 x 125A 400V Socket
Deep Sea Control Panel
The Deep Sea Electronics 7310 Auto Start Control Module monitors the speed, oil pressure, coolant temperature and levels. With this module you can get up-to-date warnings such as shutdown and engine status on a back lit LCD screen. Stay in control of your consumption with fuel usage and low fuel alarms. Other features include 2 wire remote start terminals, service hours counter, CAN engine support, a configurable event log and battery voltage monitoring. This control panel is fully lockable for security and equipment safety.
Optional Configurations
This unit can be customised and fitted with extras in Stephill’s UK manufacturing facility to suit your individual requirements. These extras include ATS Panel, Road Trailer (certified to 2007/46/CE - Ball or Ring Hitch), Engine Coolant Heater, Mains Battery Charger, and Litton Connectors.
