Energy-efficient speed control
FRQ frequency inverters are one of the most energy-efficient ways of controlling motors.
Integrated pole sine filters
The FRQS/FRQ5S frequency converters have integrated all pole sine filters as standard. Therefore there is no need for shielded cables for the installation. So they are suitable for retrofitting too.
They can also control motors which, due to their design, are not usually suitable for frequency inverters, f.g. external rotor motors.
Plug & Play
The Systemair FRQ series is pre-configured in the factory to ensure a quick and cost-efficient commissioning process. It also makes them suitable for retrofitting.
This series of frequency inverters offers a simple and energy-efficient solution for controlling motors.
The types in the FRQS and FRQ5S series also have an integrated all-pole sine filter as standard. This means that no shielded cables need to be used for installation, making the devices ideal for retrofitting existing systems. These frequency inverters are also able to reliably control motors that are not usually suitable for frequency inverter operation due to their special design, such as external motors.
All types have:
Input contact for external enable
Potential-free operation signal contact
Interference emission in accordance with EN 61000-6-3
Interference immunity in accordance with EN 61000-6-2
Protection class IP54
When operating with explosion-proof fans, the inverters must be placed outside the EX-zone.
FRQ series:
Analogue input for specifying the fan speed via external signal (0-10V)
Max. Motor supply cable length 10m (shielded)
Not suitable for external motors
FRQS series:
Analogue input for setting the fan speed via external signal (0-10V)
Also suitable for external motors and for operation with several motors in parallel
FRQ5 series:
The fan speed is set via the integrated 5-step switch:
Step 0 = 0Hz; step 1 = 10Hz; step 2 = 20Hz; step 3 = 30Hz; step 4 = 40Hz; step 5 = 50HzMax. motor supply cable length 10m (shielded)
Not suitable for external motors
Including LED for error Signaling
FRQ5S series:
The fan speed is set via the integrated 5-step switch:
Step 0 = 0Hz; step 1 = 10Hz; step 2 = 20Hz; step 3 = 30Hz; step 4 = 40Hz; step 5 = 50HzAlso suitable for external rotor motors and for operation with several motors in parallel
