Constant Voltage Regulated 12/ 24 15 amp
Cat. No. SC-CVP12/24-15
Weight 3 lbs

Model: CVP 12/24 - 15


Used to keep your Pump voltage constant as the battery discharges from 14 to 11 V, or from 28 to 22 V. Contains integral Fusing, LVD and Float Switch Control.

As your battery discharges your pump slows down and you lose performance, water flow and pumping head. This regulator takes your battery voltage, irrespective of what it is, and produces a constant "full charge" voltage which keep pumps and motors at full output and your system at optimum performance. This is married to an LVD and a float switch control with a fused battery connection for a complete low cost pumping controller.


  • Low Cost

** Special verisons of this model have the pumping functions removed and the unit is used only as an up converter producing a regulated output or as a battery charger for a higher voltage battery from a lower voltage battery. CVP 12/24-15M specifies this model. Other special models CVP 12/24-15PV charge control a higher voltage battery from solar panel input with MPPT.
