12.8.1-GB
Electronic controller for variable voltage 1~ motors
Speed controller with input 0-10 V and controller
(P-controller) for refrigeration and air conditioning
αmini
Type: PKE-2.5V(E)
Examples of applications for controlling variable voltage 1~ fans
• Function: Speed control
- Manual adjustment of output voltage using integral or external control signal (0-10 V) e.g. of Ziehl-Abegg controllers
type „Unicon“ (for: extraction systems, warm-air heaters, air curtain installations, central extraction systems, variable
air volume systems (VVS), clean room systems, laminarflow-work benches)
- Operation with two adjustable output voltages and external switch-over by potential-free contact
• Function: Temperature-/ pressure control
- PKE-2.5VE (Part-No. 303500) and PKE2.5V (Part-No. 303512) for increasing speed for increasing actual value (cooling function)
·Temperature control for: extraction systems, equipment cooling, liquid-cooling, chillers
·Pressure control refrigeration for: condensers
- Special version PKE-2.5VE (Part-No. 303597) for increasing speed for decreasing
actual value (heating function)
·Temperature control for warm-air heaters
Equipment
• Voltage supply for external units e.g. sensors +24 V (I
max
= 20 mA)
• Internal LEDs for operation and fault
• Semiconductor fuse
• Power connection prevents incorrect connection (can be connected with a plug)
• Function: Speed control:
- Input for external speed setting signal: 0-10 V (R
i
> 100 kΩ), 0-20 mA, 4-20 mA
- Connection 24 V DC for speed setting via external potentiometer
(10 kΩ Poti with dropping resistor 13 kΩ)
• Function: Temperature-/ pressure control:
(air velocity control and air volume control not possible)
- Input for sensor signal 4-20 mA, 0-10 V, KTY10-6 (temperature sensor) e.g. for:
▪ pressure sensor for head pressure controlling (e.g. type DSF2-25)
▪ temperature sensors type „TF..“
(e.g. room-, immersion-, contact sensor, air duct sensor)
Type: PKE-2.5VE PKE-2.5V
