General

Proportional 0-10V or 3-position modulating control of Frese OPTIMA Compact valves in heating, ventilating and air conditioning systems.

Due to the self adaption of stroke length, the actuator provides full utilization of the OPTIMA Compact valve modulation.

Supplied with the Frese OPTIMA Compact PICV valves (DN40- DN200).

Features

• Self calibrating stroke up to 52 mm
• 3-position or 0-10 V modulating control within the same actuator
• Voltage control signal range can be selected by use of dip switches.
• Linear or EQ% characterization available on the same actuator
• Small outer dimensions
• Removable cable
• Auto zero detection
• Feedback signal
• IP 54 protection
• The electronic circuit of the actuator ensures that the running time is the same, regardless of the stroke of the valve
• Manual operation handle on the actuator
