Product Description:
The VACON0020-1L-0004-2 is a Danfoss VACON 20 series drive, with reference code 136G9516. It comes in a frame size of MI2 and weighs 0.7 kg, while its enclosure class is IP20. This drive allows 30 meters of maximum motor cable length and a proper protective earth connection is mandatory due to its leakage current that exceeds above 3.5 mA.
The VACON0020-1L-0004-2 drive operates with a supply voltage of 208 to 240 V at 50/60 hertz in a single-phase input system and it supports a nominal output current rating of 4.3 A. Its overload capacity allows 150% current for one minute in ten minutes that equal 5.6 A and its motor power rating is 0.75 kW. The unit’s output voltage is adjustable from zero to supply voltage and its output frequency range extends from 0 to 320 hertz. It offers control methods including V over Hz and sensor-less vector. Its switching frequency can be set from 1 to 16 kHz, while the factory setting for switching frequency is at 4 kHz and it offers precise frequency reference resolution of 0.01 hertz. The VACON drive includes six digital inputs as well as two analog inputs. Its analog inputs can be configured for 0 to 10 V at 4 to 20 mA. It provides one digital output with open collector that is rated 35 V at 50 mA and two relay outputs are integrated for additional control functions.
The VACON0020-1L-0004-2 drive meets vibration and shock standards for reliable operation, while its EMC emission class is of category C2 with an integrated RFI filter that is changeable to category C4 as well, when required. The unit needs five minutes after disconnecting power before handling terminals and its recommended fuse size is 20 A. It offers RS-485 interface with Modbus RTU for communication as well.
