Description

Standby Power (ESP)
Standby power is defined as the maximum power available during a variable electrical power sequence, under the stated operating conditions, for which a generating set is
capable ofdelivering in theevent of a utility power outage orunder test conditions for up to 500 hours of operation per year under average of 70% load.Overloading is not
permissible
Prime Power (PRP)
Prime power is defined as being the maximum power which a generating set is capable of delivering continuously whilst supplying a variable electrical load. Average load should
be 70%. The generator can be overloaded 10% for 1 hour per 12 hours.
DESIGN SPECIFICATIONS

BASE FRAME
The complete genset is mounted as whole on a heavy-duty fabricated, steel base
frame. Antivibration pads are fixed between the engine/ alternator feet and the
base frame.
Base frame design incorporates an integral fuel tank.
The generating set can be lifted or carefully pushed / pulled by the base frame,
Lifting eyes allow easy transportation by a crain.
Dial type fuel gauge and drain plug on the fuel tank.
