Product Description:
The VACON0020-1L-004-2+DLDE Low Voltage Drive is manufactured by Danfoss, known for providing reliable drive technology for industrial applications. This model is built to deliver stable performance and efficient motor control in demanding environments. The drive features a power rating of 0.75 kW (1 HP) and supports an output current of 4.2 A.
The VACON0020-1L-004-2+DLDE Low Voltage Drive operates with a supply voltage of 1 × 208 to 240 V AC (single phase) and maintains an input voltage tolerance from -15% to +10% of nominal. The drive is designed for a frequency range of 50/60 Hz ±5% with an input current of 9.5 A. It achieves high efficiency, reaching ≥97% at nominal load under standard operation. The drive uses an adjustable switching frequency with a default of 6 kHz. It supports an overload capacity of 150% for 60 s and 175% for 2 s. The motor control type is V/Hz control with flux optimization for reliable performance across applications. Its enclosure class is IP20 and it employs forced air cooling for thermal management. The drive can operate in an ambient temperature range of -10 °C to +50 °C without derating. Storage conditions allow -40 °C to +70 °C. It withstands relative humidity from 0–95%, non-condensing. Installation is supported up to 1000 m altitude without derating, with a 1% derate per 100 m above. The drive meets EMC category C2 according to EN61800-3.
The VACON0020-1L-004-2+DLDE Low Voltage Drive provides 5 digital inputs (programmable), 1 analog input (0–10 V, 0/4–20 mA), 1 analog output (0/4–20 mA), and 1 relay output (250 V AC / 30 V DC, 2 A). Communication is enabled through RS-485 (Modbus RTU) with optional fieldbus modules. A detachable keypad with LCD display supports configuration and monitoring. Dimensions are 146 × 72 × 172 mm and the weight is 1.1 kg.
