UNIVERSAL RELAY DIVERSION/DUMP CHARGE CONTROLLER REGULATOR

MODEL 1URDC 12V (Board Version 2.X.X)

For both EMRs (ElectroMechanical Relays) and SSRs (Solid State Relays)

For Wind, Solar and Hydro can also work with 24, 36, 48 and 60V systems. See manual for details.

These were going to be the first production run, but in the time sense I first ordered the PCBs I did a little redesigning and a few improvements. So I'm clearancing these out for $45 USD each. When the new ones come out they will sell for $69.95 USD each. No printed manual is included so please DOWNLOAD IT HERE. 

DESCRIPTION

  The Universal Relay Diversion Controller/Regulator is a low cost Microprocessor controlled dump/on-off type controller designed for the DIY (Do It Yourselfer). It is designed to switch up to 4 conventional automotive style electromechanical relays (EMR) with up to 800ma total coil current draw with up to 160A power handling capability. Also unlike other controllers of this type of design, this will also control DC-DC Solid State Relays (SSR) in conventional (Dump) diversion mode or use a 2-Stage charge algorithm and a Equalization mode. It is theoretically able to switch up to 32 SSRs at 25ma each (untested). If using just 40 amp SSRs that adds up to a potential 1280A 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 a area protected from the environment or in a user supplied enclosure.
