The 900 UniPower is a single-speed winch that provides the advantages of a low-profile manual winch with the power of a 12- or 24-volt, low amp-draw motor, as desired.
Particularly well-suited to its task, the 900 UniPower is currently the only winch on the market designed from the start as an electric winch, rather than as a modification of a manual winch.
A resulting unique advantage of the UniPower is that the motor can be partially embedded inside the drum, so it protrudes only 4-1/8" (105 mm) below the base of the winch – a critical feature for small boats where walking head space under the cabin ceiling is limited.
With the 900 UniPower, even small yachts can now enjoy the convenience of raising sails or trimming genoas or mainsails with 900 kg of pulling power at the touch of a button. (Comparable to the power of a #40 electric winch.)
To make installation easier, Harken UniPower winches include, in addition to the winch and motor, a separate up/down solenoid control box with a built-in current limiter.
900 UniPower winches are available in five finishes including a durable lightweight aluminum drum, or a mirror-finished chromed bronze drum.
The Radial winch drum’s gripping surface is specifically shaped for maximum performance of each drum material and features diagonal ribs (rather than textured abrasive materials) to maximize gripping power – greatly reducing wear on your sheets and halyards. At the same time, the ribbed surface allows for smooth, controlled easing while under load.
The patented angle of the ribs also serves to drive line wraps downward when easing to keep them on an area of the drum that provides the best control.
The self-tailing mechanism allows a single crew member to quickly and easily trim or raise sails.
What's in the box?
(1) UniPower winch with motor and (1) single-speed combination solenoid control box with a built-in digital current controller (WLC200R) to protect your deck hardware by electronically limiting the winch’s maximum pull to 1,984 lb (900 kg). (The load controller used to be sold separately as an upgrade.)
The control box has terminals for analog switches as well as digital switches.
The customer must supply a waterproof switch, 80A (12V) or 40A (24V) circuit breaker, 5A inline fuse, and wire for making connections.
