Overview
A Diesel Generator Set - DOOSAN BC-H90D-50 (72 kW / 90 kVA) standby rating defines the BC-H90D-50, a diesel genset built around a SP344CC engine, open type configuration, set for 50 Hz and three-phase four-wire, at 110/208 V – 277/480 V.
This is the usual backup rating for a commercial site or a small industrial unit: it carries the essential load without oversizing the installation, and leaves headroom for motor and compressor starting. BCP’s Doosan range spans 8 to 1100 kVA with Doosan power, intended for standby duty and for extended running depending on how the fuel and cooling system is specified.
Typical applications
- Small industrial units and production workshops
- Hotels and shopping centres
- Clinics and diagnostic centres
- Pumping and water treatment systems
- Construction sites and temporary camps
Standby and prime ratings
The standby rating (90 kVA / 72 kW) is what the set delivers during a grid outage, for a limited number of hours a year and without sustained overload. The prime rating (PRP) allows continuous duty with varying load. Sizing starts from the real load in kW, corrected by power factor, with headroom left for motor starting.
Frequently asked questions
What is the difference between standby and prime?
Standby is the power available in an emergency, limited to a set number of hours a year; prime is what the set can sustain continuously with varying load. A set sized for standby should not be used as prime generation without re-checking the duty.
What voltage and connection does the BC-H90D-50 deliver?
It is offered at 110/208 V – 277/480 V, three-phase four-wire, 50 Hz. Final nameplate voltage is fixed at order stage according to the site network and the transfer arrangement.
How much headroom should be left above the real load?
Allow 20–25 % above the measured load in kW to absorb motor starting and to keep the set from running continuously above 80 % of its rating.
