Over voltage protection

When the voltage reaches over 28V, the pump has auto-protect and will shut off.  When the voltage falls below 28V, the pump will restart automatically.

Over load protection function

When the current reaches over the rated current, as can arise if the impeller is stuck due to debris. The pump will automatically stop and prevent damage, it will restart when the current falls again.

PV operated

For solar system loops, the TD5 pump can be powered directly from a PV panel. The sun comes up, heat builds in the solar hot water panel and at the same time electricity is made in the PV panel.

The pump slowly starts with the smallest amount of current and pushes the heated water to the storage tank.

Simplicity at its finest eliminates all controllers, thermostats and sensors.

Soft start-up

The TD5 Solar DC pump has a soft start-up feature which reduces high in-rush current. When the photovoltaic panel provides sufficient power, the pump goes through the alignment phase by turning the rotor into the position required for start-up. The processor then waits until the capacitor is sufficiently charged.
This enables a start-up with minimal power (less than two watt).
Cycling due to unsuccessful attempts is minimized, even after prolonged shutdown, the pump will start reliably .

Automatic polarity protection

Red is plus, black is minus, if wrong polarity will not damage the motor for it has the automatic polarity protection function.
