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 is directly from the fan. No additional supply voltage is required.

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.
