Definition of Ratings & Reference Conditions :
Prime Power (PRP) is the nominal output continuously available, where the average load (variable) does not exceed 80% of the prime
power rating. 10% overload is available for a maximum of 1 hour in 12 hours of operation.
Standby Power (LTP) the maximum output available (at variable load), for up to 500 hours per year. The average load (variable) must not
exceed 80% of the standby power rating. No overload is available. The genset must not operate, at standby rating, in parallel with the
public utility under any circumstances.
Standard Reference Conditions: air inlet temperature 25°C (77°F), barometric pressure 100kPa [110m(361ft) altitude] and 30% relative humidity.
Notes: The above ratings may be subject to derate at different operating conditions. Please see the Derate Guidelines on the Agen wesite.
All power ratings and reference conditions in accordance with ISO 8528-1 and ISO 3046-1.
Above ratings are for 400V, 50Hz, Cos ?=0.8

* The self-regulation is obtained through an electronic regulator. The regulator is fed by an auxiliary winding which guarantees an almost constant supply under any possible operating condition of the generator.
** This regulator is equipped with a low speed and overload protection with an adjustable intervention threshold, it works at 50/60 Hz, it has adjustable voltage stability and it offers the possibility for a remote voltage regulation.

Control Module Specification
|
Automatic Engine Control Module DSE521K
The Model 521 is an Automatic Engine Control Module designed to automatically start and stop the engine.
It will indicate the operational status and fault conditions, automatically shut down the engine and indicate the engine failure by a flashing LED on the front panel.
Other simultaneous faults are indicated by steady LED.
Operation of the module is via a three position rotary key-switch mounted on the front panel with STOP, AUTO and MANUAL positions.
Remote PC-controlled engine starting and stopping is also featured.
Configurable inputs available for:
* Low Oil Pressure
* High Engine Temperature
* Remote Start.
