Mechanical Specifications

Weight:

  • approx. 2 lb.

Size:

  • 4.5″ x 2.5″ x 2″ nominal, resembling a junction box with mounting feet

Connections:

  • Power: PV and Load
    • 6 inch # 16 AWG flying leads
    • Input: Red = PV +, Black = PV –
    • Output White = Pump +, Blue = Pump –
  • Signal: float switch, 12/24 V select
    • 6 inch # 24 flying leads yellow: connect to PV – = OFF for float switch operation
    • 6 inch # 24 flying leads purple: connect to PV – = 24 V operation disconnected = 12 V operation
    • 6 inch # 24 flying leads red / black: Output Current Sense scaled at 50 mv = 10 A

Operating Temperature:

  • -40 to 70 deg. C

Humidity:

  • N/A Nema 4 enclosure

Application Notes:

  1. This Pump Power Tracker(TM) is quite capable of putting out over 15 amps into a stalled load even from a single 30 watt 4.5 amp panel. It is recommended that a fuse or overtemperature switch matched to your pump motor be incorporated in the system to protect your pump or motor.
  2. Float switch operation draws microamps of current, ie: small wire gauge, allowing long distance runs between float switches/holding tanks, and PV / pump driver without the need to string long lines of heavy gauge wire.
  3. Unit is a true 15 amp unit, all necessary derating already accounted for. Unit is capable of 20 amp operation with normal derating practices.
  4. As with all electronics, it is recommended the unit not be mounted in direct sunshine.

Note: In the interest of continuous product improvement, specifications subject to change without notice.
