Super-silenced single-phase KOHLER 21EKOZD 21 KVA AVR

Kohler 21EKOZD single phase 21 KVA marine generator with 1500 rpm motor. The KOHLER 21EKOZD single-phase marine generator is built with a soundproof enclosure that makes it supersilenced. The KOHLER 21EKOZD single-phase marine generator is built with a 4-cylinder, 4-cycle Kohler diesel-powered engine, closed cooling system with heat exchanger. The alternator of the single-phase KOHLER 21EKOZD is brushless with AVR voltage regulator and water-cooled. With its small size, the 21EKOZD is also suitable on boats of various sizes.

Features of the KOHLER 21EKOZD alternator

- Brushless rotating field design allows power to be obtained from stationary conductors.
- Windings are vacuum-impregnated with epoxy paint for reliability and long life.
- Rotors are dynamically balanced to minimize vibration.
- Copper windings ensure minimal heat buildup. Insulation meets NEMA standards for Class H insulation.
- Connected directly to the motor, the generator features sealed precision ball bearings with a precision machined steel sleeve in the end bracket to prevent shaft misalignment and extend bearing life.
- Mounted on a drip-proof tray.
- Equipped with a four-conductor reconnectable stator.
- Capable of withstanding a line-to-neutral short-circuit current of up to 300% of rated current for up to 2 seconds. (Short circuit performance IEC 60092-301).
