HOW TO SELECT
A GENERATOR
Range of motor capacities that can be used with Denyo generators.
Choosing generator output according to motors and other loads is made simple by
referring to the motor capacity range and generator output in this table.

Other Options
The following options are also available:
− Reverse power relay
（For DCA-125 and above.Provided as standard feature for DCA-800, D CA-110 0 SP）
− AC power meter
（For DCA-125 and above.Provided as standard feature for DCA-800, D CA-110 0 SP）
− Dual-voltage specifications
（For DCA-25USI3,45USI2,60ESH,60USH2.Provided as standard feature for
DCA-25ESK,25ESI,45ESI,60ESI2,75SPI,DCA-100 to 800.Not available for
DCA-13LSK,13LSY,15LSK,20LSK,35SPK,DCA -1100SP）
− Bearing/stator temperature gauge （For DCA-125 and above. Provided as
standard feature for DCA-800SPK,800SPM,DCA -1100SP）
− Lubricant temperature gauge
（Provided as standard feature for DCA-220 and above）
− Overspeed protection device
（Provided as standard feature for DCA-600SPK,DCA-610SPM,DCA-800SPK, 800SPM,
DCA -1100 SP）
− Keyed fuel tank cap
（For DCA-13 to 1100）
− Mounting of muffler flange
Other options for different ranges and operating capabilities are available. Please feel free to
consult with Denyo.
* Some options may not be available depending upon the model. Confirm the details with a
Denyo sales person.
Motor usage examples in the above table are benchmark values : generator capacity will differ according to
the required momentary voltage drop, motor load factor, and size of startup capacity, as well as motor age
and efficiency.
Notes
− Momentary voltage drop when a motor starts up is assumed to be within 30% of no- load voltage.
− Motor startup kVA is assumed to be 7kVA per 1kW.
− Motor efficiency is assumed to be 85%, and load factor about 90%.
− Values shown for Y-△ startup（1）and Y-△ startup（2）are open and closed, respectively; needed generator capacity differs depending on
startup state.
− Not appropriate for determining the capacity of emergency generating equipment（especially disaster-prevention generating equipment）.
