AME 855 Electrical Actuator
Brand: DanfossActuator is primarily designed to regulate valve in the respond to the demand of a controller in district heating/cooling, heating, ventilation and air conditioning systems.
Actuator AME 855 can be controlled by electronic controllers with modulating or 3-point control output. Actuator can be used with VF3 valves (DN 200-300).
Features- 3-point or modulating control
- Easy to use manual operation ( monitoring on terminal R)
- Position indication
- LED signaling
- Direct or inverse function
- Automatic adaptation of stroke to valve's end positions which reduces commissioning time
- Voltage or current input Y
- Voltage or current output X (for current output, accessory is needed)
- Frost protection function (for detailed information read the Functions section in the data sheet)
- Blockage detection
- Internal temperature control – integrated heater + overheat protection
- Wire break detection (only modulating actuator)
- Selectable hysteresis
- Auto test function
- Auto pause function
- Potential-free position switches (accessory)
- Remote reset possibility
