50 ST E1

Product catalog summary
Product Overview:
The document provides technical specifications and installation guidelines for the Andersen Powered Winch model RA2050011300, RA2050001300, specifically the 50 ST E1 model. This winch features a self-tailing mechanism, an E1 electric motor, and offers two-speed manual and one-speed electric operation at 12VDC.

Specifications:
  • Power Ratio: 1st speed = 15.7:1, 2nd speed = 49.3:1
  • Gear Ratio: 1st speed = 2.8:1, 2nd speed = 8.8:1
  • Maximum Working Load: 1000kg (2200lb)
  • Rope Size: 8-14mm (5/16 - 9/16”)
  • Physical Dimensions: Drum Ø D = 89mm, Base Ø B = 181mm, Height H = 208mm, Line Entry L = 90mm, Max Deck K = 57mm, Gear Length S = 65mm, Motor Depth J = 191mm, Motor Length N = 300mm, Weight = 21kg

Electrical Installation:
  • Wire Length and Size: 0-3m requires 35mm² wire, 3-8m requires 50mm² wire
  • Fuse/Circuit Breaker: Must be a ‘slow blow’ or ‘long delay’ type to handle start-up current spike
  • Start-Up Motor Current: 600A
  • Additional Battery Capacity per Winch: 123Ah
  • Minimum Battery Bank Capacity: 300Ah to maintain minimum voltage levels

Installation Notes:
  • Motor units come with an installation manual, push button, and cable terminals. Circuit breakers are available separately.
  • Motor can be rotated at 45° intervals, affecting Ox and Oy values.
  • Full installation dimensions and wiring diagrams are available in the product manuals downloadable from the Andersen website.

Performance Considerations:
  • The motor will cut out at pre-determined current and temperature limits.
  • Recommended to consult a qualified marine electrician for battery capacity requirements.

Suitable circuit breakers available separately. 3 The current “spike” generated at motor start-up, for a period of no more than 0.1 seconds. 4 This is the minimum additional Ah (Ampere hours) battery capacity that will be required to run one winch. Assuming a single winch, used for of 15 minutes (0.25hr) per day at a load of 1/2 MWL = 165A. This equates to an Ah figure of 41Ah. The number of Ah for all other electrical equipment ADDITIONAL MINIMUM BATTERY BATTERY CAPACITY BANK 4 PER WINCH CAPACITY 5 123Ah must be added to this figure to determine the Ah requirement of the total battery bank capacity. A good rule of thumb is to use 3 x this total Ah figure as the minimum additional battery capacity for your battery bank. We recommend you contact a qualified marine electrician for advice. 5. This is the minimum recommended battery bank capacity to ensure minimum 10.5V is maintained in 12V systems, and 21V in 24V systems at start up current. Based upon battery CCA value at -18C and assuming fully charged batteries and no losses in wiring and connections.
