Solar Converters PPT16, Linear Current Booster, NEMA 3R enclosure

Solar Converters Inc - PPT 16 3R
12V/24V Motor at 16 Amps, Dual Voltage
Linear Current Booster / Pump Driver

Application

Used to control and power a DC motor from a solar panel. The unit prevents stalling of the motor under less than full sun condition. The power of the sun is transformed to the motor running conditions so as the sun goes down the motor slows down instead of stalling. Conversely, or as the sun comes up the motor starts running much earlier instead of staying stalled for hours when it could be running. This translates into more running time of the motor where it spends a lot of time working instead of stalled doing no work.

Features

• Voltage Limited Output
• Internal fuse - 25A automotive style fuse
• Greatly increases water flow, even under reduced sunlight conditions (over 40% likely)
• Transient Protected on the input and output
• Float Switch Input for on/off control, both Normally Open and Normally Closed float switch compatibility
• Single Unit Switchable: 12/24/36 volt PV array input, 12/24 volt motor output
• Pump Protection Features - Well Dry, Low Sun, Current Limited, Temperature Limited
• Ultra High Efficiency >94%
• Multiple Enclosure options available - NEMA 3R, NEMA 4R, NEMA 1R, no enclosure - see below for part #s

User Controls: Pump On/Off, Reset

Protections

• Dry Well:
  • Unit senses when the well is dry by sensing very low pump current - no load on pump. If the condition exist for three seconds, the output is disabled for 20 minutes to allow the well to refill. Reset clears this condition.
• Low Sun:
  • Unit senses when the sun is producing too little power to reliably run the motor (1/4 power point) and will shut off for 3 minutes to prevent unnecessary brush wear.
• Temperature Limited:
  • The uinit will reduce motor power if the unit is running too hot to maintain a constant unit temperature and prevent unit failure form overtemperature
• Current Limited:
  • The unit will current limit its output to protect the unit and the load from jammed motor/ low resistance operation. An external fuse rated for the motor is recommended.

Application Notes

1. This Pump Power Tracker(TM) is quite capable of putting out over 60 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. The unit's internal fuse will protect the unit.
2. Float switch operation draws microamps of current, i.e. 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 16 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.
5. Solar panel or energy limited input only.

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

Special Shipping Note:
All Solar Converter Products are behind in production. These items are usually shipped directly from the manufacturer in Canada. They cannot be shipped by any expedited methods such as UPS Blue or Red. They will generally be shipped via Canadian Express Mail which avoids import brokerage fees of $50-$60. Lead time on these products may be up to 4-6 weeks depending on their production. This is true of all Solar Converters products with the exception of the battery desulphator (item code SORBD-2) that we stock in our warehouse. If you want Solar Converters products to be shipped by normal Canadian Post, but would prefer to have the rest of your order to be shipped by a faster method, please write this information in your order's notes during checkout.
