New ALPHA SOLAR

Product description

The new ALPHA SOLAR is designed

to be integrated in all kinds of thermal

solar systems with either variable

(matched-flow) or constant flow rate.

High-efficiency ECM (Electronically

Commutated Motor) pumps, such as

ALPHA SOLAR, must not be speed-controlled by an

external speed controller varying or pulsing the supply

voltage.

The speed can be controlled by a low-voltage PWM

(Pulse Width Modulation) signal from a solar controller

to optimise the solar harvesting and temperature of the

system. As a result, the power consumption of the

pump will be reduced considerably.

If no PWM signal is available, ALPHA SOLAR can be

set to constant speed, only switched on and off by the

controller.

PWM input profile C (solar)

Features

• Constant speed.

• PWM C profile. The PWM signal is a method for

generating an analog signal using a digital source.

• Low EEI (Energy Efficiency Index).

• Maintenance-free.

• Low noise level.

• Very simple installation.
