MODEL 1URDC-Basic 12V (Board Version 1.2.X)
For both EMR’s (ElectroMechanical Relays)
and SSR’s (Solid State Relays)
2-STAGE charging using SSR'S
For Wind, Solar and Hydro
(See manual for use with different voltage LA Batteries)
The Universal Relay Diversion Controller/Regulator is a low cost, Microprocessor controlled Diversion/Dump type controller designed for the DIY (Do It Yourselfer). It is designed to switch up to 8 conventional automotive style electromechanical relays (EMR) directly with up to 1.25A total coil current draw with up to 320A power handling capability.
Also unlike other controllers of this type of design, it will also control DC-DC Solid State Relays (SSR) in Legacy/Conventional (Dump) diversion mode or use a much more efficient 2-Stage charge algorithm including a manual Equalization mode. It is theoretically able to directly switch up to 50 SSR's at 25ma each (untested). If using just 40 amp SSR's that adds up to a potential 2000A (4000A using 80 amp SSR's) power handling capability.
To keep cost down, this controller was designed for the DIY (Do It Yourselfer) and is the BOARD ONLY and does not include an enclosure. It can be mounted directly on a wall in an area protected from the environment or in an Optional or user supplied enclosure. To keep cost down and prevent unnecessary waste this manual is available in PDF format only (just printout what you need). The latest version of this manual is Free for DOWNLOAD HERE 1URDC_Basic_Manual.pdf from WindAndSunPower.com Please download and read before purchasing.
