PCA

Pressure Controller for EC Fans

  • Two control modes 

  • With or without outdoor temperature compensation 

  • Easy set-up

  • Enclosure class IP54


2-control modes

The PCA pressure controller features two possible control modes, variable air volume (VAV) and constant air volume (CAV)


Easy set-up

The PCA pressure controller is easy to set up and has a user-friendly menu. 


Supply voltage

Supply voltage to the PCA pressure control might be taken from the fan if it can provide 10-24 V DC (Imax = 6 mA) for PCA 1000D2 or 10-24 V DC (Imax = 28 mA) for PCA-2 1000D2. If the fan can't supply needed voltage and current you will need a transformer for the PCA-controller.

With or without outdoor temperature compensation

PCA 1000D2 is without outdoor temperature compensation and PCA-2 1000D2 is with outdoor temperature compensation.


PCA 1000D2
Control unit for pressure and constant flow regulation with 0-10 signal
For pressure control of fans whose speed can be controlled directly with a 0-10V signal, or to provide a pressure-dependent 0-10V signal to e.g. a frequency converter which in turn regulates the speed of the fan.

Variable Air Flow (VAV)

Constant Airflow (CAV)

Simple start-up, user-friendly

When connecting with products with output for permanent voltage supply 10-24 V DC (Imax = 6 mA) no external voltage supply is required. Otherwise, a separate transformer with output voltage 10-24 V DC (Imax = 6 mA) is required.
The PCA 1000D2 can usually be supplied with voltage from our EC fans with a permanent 10V output, which means that an extra transformer is not required. 

The PCA 1000D2 has an adjustable measuring range of 0-1000Pa. The calculation of the volume flow is performed by entering the K-factor of the application.

PCA-2 1000D2
Control unit for pressure and constant flow regulation with 0-10V signal and outside temperature compensation

For pressure control of fans whose speed can be controlled directly with a 0-10V signal, or to provide a pressure-dependent 0-10V signal to e.g. a frequency converter which in turn regulates the speed of the fan.

Variable Air Flow (VAV)

Constant Airflow (CAV)

Simple start-up, user-friendly

MODBUS

When connecting with products with output for permanent voltage supply 10-24 V DC (Imax = 28 mA) no external voltage supply is required. Otherwise, a separate transformer with output voltage 10-24 V DC (Imax = 28 mA) is required.
Our EC fans are unable to provide a permanent output voltage of 10 V, 28 mA to power the PCA-2 so in these cases a separate transformer is required. For example the transformer with article number 212486.

The PCA features an enclosure class IP54.
