DelStar Alternators

Alternators from DelStar series offer outstanding charging characteristics combined with an innovative, carbonless design. This means a longer service life, which corresponds to today’s maintenance intervals of modern engines, and at the same time an early start of charging in combination with a high power output even at low speeds, which makes our DelStar alternator series unique.

Optionally available with built-in or separate regulator and with an air intake cap to draw fresh air from a colder point to cool the generator by means of a hose.

Main DelStar Features:

• HIGH EFFICIENCY: High efficiency means cooler internal alternators operating temperatures resulting in less engine horsepower required and maximizing fuel savings. Our unique air flow design offers a more efficient air flow through the windings which directly translates In maximum output and efficiencies.

• TEMPERATURE RATING: All our alternators are validated to work and operate In today’s ambient air temperatures of up tot 125°C / 257°F

• DEBRIS FREE & COOLER OPERATION: For high debris or high temperature environments, all DelStar series alternators are available with on optional Air Intake Cover by adding the letter ‘D’ after the part No. the Ducted air allows filtered or fresh air flow to the unit which will Improve output, efficiency and extends the alternator service life.

• SOFT START DELAY (SSD) & LOAD RESPONSE CONTROL (LRC): A newly Introduced SMART REGULATOR where at engine start up, the regulator monitors the (low) engine RPM, it controls and gradually Introduces alternator output to eliminate engine torque decrement due to a sudden and abrupt load transition at low RPM.

 OVERVOLTAGE SHUT-DOWN (0SD): Designed to protect onboard electronics that are very sensitive to high voltage conditions, by shutting down the alternator output and restoring output only when the voltage is stabilized to or below the regulator voltage set point.

APPLICATIONS: School & Shuttle Buses, Emergency Vehicles, Utility Vehicles, Marine & Mining, Agricultural & Industrial Construction, Trains

Below is a brief overview of the individual series:

161 Series This is the smallest and most compact series with the technical characteristics of the larger series, brushless. Available in 12Volt - 200A and 24 Volt from 125A - 160A.
170 Series This series is also appreciated for its compact dimensions, but here - with the exception of the 24V - 170A version - a so-called "hairpin" stator is used in addition to the features from the 160 series to enable a higher power output. Available in 12 Volt - 350A, 24 Volt - 170 to 240A with a J-180 and PAD mount attachment. Only the 24 volt - 170A version has a conventional stator.
180 Series The most popular series. 12 volts - 350A and 435A, 24 volts - 200A, 250A and 265A. In addition to the J-180 and PAD-Mount versions, there are also versions with the European T1 mounting, optionally clamping device 60 ° right or left.
250 Series The latest series. This version performs in 12 volt - 430A with a 7 inch mounting foot. In 24 volt - 320A optionally with a J-180 mounting, 7-inch mounting foot and as T1 mounting, optionally with a clamping device 60 ° right or left.
300 Series Available in 24 volts - 330A and 400A. This DelStar alternator is supplied with a saddle attachment and a shaft with multiple teeth.
This corresponds to the Delco 50DN assembly. Now also available with built-in controller.
400 Series This is the largest DelStar alternator available with an output of 24 volts - 550A. The assembly and drive correspond to those of the 300 series.
DelStar Alternators designed to be used with Mastervolt regulator Alpha PRO III. Series 161, 170, 180, 250, 300 and 400 all have been adjusted to work with a Mastervolt regulator.

If  installation needs to intake cooler & clean fresh air due to any environmental influences, we would like to present the following “Air intake solution”:

Variant (D) including a black air intake cap to ensure a supply of cooler and cleaner fresh air using a hose, for ex.:
