PCA

Demand Controller for EC fans

Precise Measurement
Flexible Control Options
Robust Construction
Wide Compatibility

Two Control Modes

The PCA pressure controller features two control modes, variable air volume (VAV) and constant air volume (CAV) making it sustainable for a range of applications and systems.

User-Friendly Operation

The demand controller simplifies configuration and operation, allowing for straightforward adjustments to ventilation parameters as required.

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 an output voltage of 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.
