Damper actuator controller, differential pressure 0–2000 Pa
Product description
SPSA-series are controllers for actuator powered dampers. They control the damper position in function of differential pressure (Pa) or volume flow (m³/hr). Their control algorithm with PI function will continuously optimise the damper position to maintain the differential pressure or airflow constant. The setpoint and all other parameters can be adjusted via Modbus RTU. Their control output provides an analogue or modulating control signal: 0-10 VDC, 0-20 mA or 0-100 % PWM. Supply voltage: 18-34 VDC. It can be used in the range of 0 to 2.000 Pa.
