6.03.2024. New fan speed controller FP-CPR1-4
In February, the Russian plant of refrigeration components Frigopoint began production of a new autonomous speed controller for single-phase fans FP-CPR1-4 to maintain a given condensation pressure.
The fan speed controller FP-CPR1-4 is designed for installation on refrigeration units in order to maintain a given level of condensation pressure in the system by changing the rotation speed of the condenser fans by regulating the voltage. The device is self-contained and has a pressure measurement port; the output voltage changes according to a proportional algorithm relative to the setpoint (screw on the front panel).
The regulator has the following principle of operation. The CPR1-4 regulator operates on the principle of changing the output voltage (phase cutting) in accordance with the measured pressure and a given setpoint. The figure shows a working diagram. There is an adjusting screw on the front panel, one turn of which corresponds to a change in the set point by 1 bar (increase - clockwise, decrease - counterclockwise
arrows).
Technical characteristics of the regulator are presented in the table:
Electrical connection:
The maximum control current of the triac is limited to 4 A when used at temperatures up to 40 C and 3 A when used at temperatures up to 30 C.
