Device Description
The VLT HVAC Drive FC100 frequency converter from Danfoss is designed for use in ventilation, air conditioning, and heating systems, taking into account their operational peculiarities. This device significantly reduces electricity consumption by automatically selecting optimal operating modes.
Power Supply Voltage and Power Range:
- Three-phase 200…240 V – from 11 kW to 45 kW
- Three-phase 380…480 V – from 11 kW to 1000 kW
- Three-phase 525…600 V – from 11 kW to 90 kW
- Three-phase 525…690 V – from 45 kW to 1.2 MW
Features and Technical Specifications
- Degree of protection: IP20/chassis, IP21/NEMA1, IP55/NEMA12, IP66/NEMA 4X
- High accuracy and stability of operation due to automatic monitoring using built-in PID controllers that adjust system parameters.
- The standard automatic energy consumption optimization function (AEO) ensures optimal motor magnetization for improving energy consumption by 5-15% at partial load.
- The device provides comprehensive information about the current energy consumption level and for the selected period.
- Automatic rotation frequency skipping function that prevents resonance phenomena and premature failure of components.
- Automatic recognition of drive belt breakage based on monitoring the current and speed of the motor.
- Fire extinguishing mode, when activated, allows the device to continue working without responding to control signals.
- Temperature control in the room based on refrigerant pressure measurement, allowing optimizing the compressor operation.
- Special mode to prevent hydraulic shocks during pipeline filling.
- Built-in function for detecting leaks and damage in the system, that signals when extreme points on the operating curve are reached.
- Cascade controller for simultaneous control of three pumps, one of which is a leader.
- Function for alternating operation of two pumps using an adaptive timer for even load distribution.
- Automatic pressure adjustment depending on the flow rate in the channel.
- Special initial acceleration mode for pumps to reduce bearing wear.
- Wide logical control capabilities based on the "event-action" concept.
- Safe Stop option that prevents unintended device start-up.
- Availability of additional devices and components upon customer request.
- Support for Plug-and-Play technology for convenient installation of optional modules.
- Local control panel LCP – digital or graphical, with the possibility of remote installation.
- Ability to use expansion boards for various network protocols.
- Built-in filters: harmonic, sinusoidal, dU/dt.
- The supply set includes an IP21/NEMA1 kit, isolation board, Profibus adapter, and USB cable.
