GD300-01A — Air Compressor Drive GD300-01A — INVT

GD300-01AGoodrive300-01A Series VFD for Air Compressor

GD300-01A — Air Compressor Drive INVT

VFD for screw air compressors with induction or synchronous motors: 3-ph 220–240 V 7.5–185 kW, 3-ph 380–440 V 7.5–500 kW, 3-ph 520–690 V 22–630 kW. Compressor logic is built in, so no PLC or separate controller is needed: two 4–20 mA (0–1.6 MPa) pressure inputs and two temperature inputs (−20…150 °C), dual PID control, sleep/wake-up and fan current-imbalance protection. SVC and V/F control, 150 % at 0.25 Hz (IM), efficiency > 97 %. The -CT version (7.5–15 kW) integrates the fan contactor and a 220/110 V transformer for the solenoid valve; a DC reactor is built into 15–110 kW models.
