Danfoss VLT® HVAC Drive FC 101 AutomationDrive frequency converters

Here is the technical parameter introduction and model list of VLT® HVAC Drive FC 101:

Technical Parameters

Power Supply:

Voltage Range: It supports three - phase power supply with voltage ranges of 3 x 200 - 240 V, 3 x 380 - 480 V, and 3 x 525 - 600 V.

Power Range: The power range is from 0.25 - 45 kW for 3 x 200 - 240 V, 0.37 - 90 kW for 3 x 380 - 480 V, and 2.2 - 90 kW for 3 x 525 - 600 V.

Input Frequency: The input frequency is 50/60 Hz.

Motor Control: It supports AMA and AEO, which can optimize motor control and improve the efficiency of the motor under steady - state operation. It also supports both asynchronous and synchronous motors, providing more flexibility in motor selection.

Enclosure and Protection:

Standard Protection Level: The standard protection level is IP20. Optionally, it can be upgraded to IP21 by installing relevant accessories, and there is also a standard protection level of IP54.

Environmental Resistance: With a coated PCB and forced ventilation that avoids electronic components, it can resist harsh environments. The maximum operating ambient temperature can reach 50°C.

Dimensions and Installation: Its compact book - type design allows for true side - by - side installation without derating, which can save space.

Built-in Functions:

Filter and Reactor: It has a built - in C3 radio - frequency interference filter to limit radio interference generated by shielded motor cables up to 25 meters. Meanwhile, C1 and C2 filters are optional. It also has a built - in DC reactor to meet the harmonic suppression requirements of EN 61000 - 3 - 12.

Other Functions: It has a built - in PI controller, an automatic energy optimization (AEO) function, a fire function, a sleep mode, and a coast - to - start function.

Communication: It supports the Modbus RTU protocol, facilitating communication and connection with other devices.

I/O Interfaces:

Digital Input: There are 4 programmable digital inputs, with logic of PNP or NPN and a voltage level of 0 - 24 V.

Analog Input: There are 2 analog inputs, which can be configured as 1 current/1 voltage or current mode. The voltage level is 0 - 10 V (adjustable), and the current level is 0/4 - 20 mA (adjustable).

Analog Output: There are 2 programmable analog outputs with a current range of 0/4 - 20 mA.

Relay Output: There are 2 programmable relay outputs (240 VAC, 2 A and 400 VAC, 2 A).

Model List

Here is an example of a specific model:

FC-101P11KT4E20H4XXCXXXSXXXXAXBXCXXXXDX: In this model, "P11K" represents a rated power of 11 KW / 15 HP, "T4" indicates a three - phase power supply of 380 - 480 VAC, "E20" represents an IP20 enclosure / chassis, and other codes represent specific features and options, such as the type of RFI filter, the presence or absence of a braking chopper, a local control panel, etc.

In general, the model of VLT® HVAC Drive FC 101 is mainly distinguished by different power levels and optional configurations. For example, models with different power values such as 0.25 kW, 0.37 kW, 2.2 kW, 45 kW, 90 kW, etc. under different voltage levels, and different models will be formed according to different combinations of optional accessories and functions.
