Delta ME300 Basic Compact Series AC Inverter for 0.75kW (1HP) 3ph motor to 2,7A at high overload or 0.75kW (1HP) to 3,0A when Fan/Pump rated. Operates in VxF or Sensorless Vector and converts fixed frequency Three Phase input to variable frequency Three Phase to control a standard AC induction, permanent magnet motor, IPM (Interior permanent magnet) and SPM (surface mounted permanent magnet).
Input Current: 2,7A at High Overload, 3,0A when Fan/Pump rated.
Input Voltage: Three phase AC 380V–480V (-15 %~+10 %), 50/60 Hz.
EMC Compliance: IEC EN 61800-5-1 Category C3 @ 30m (Industrial). Disabled by default, can be enabled via screw.
Frame Size: B3 72mm Wide x 143mm Deep x 142mm High. IP20.
Mounting via 4 x M5 bolts (not supplied) at rear on 60mm x 130mm centres. (Optional DIN-Rail mounting available - see linked products below).
Weight: .9kg.
Overload:
150% for 60 seconds. High Overload. (Heavy Duty, HD), 200% of rated output current for 3 seconds.
120% for 60 seconds. Fan/Pump Rated. (Normal Duty, ND), 150% of rated output current for 3 seconds.
Speed Control Range: 0-599Hz. +/- 0.1%.
1 : 50 (V/f, SVC control for IM, heavy duty).
1 : 20 (SVC control for PM, heavy duty).
Switching (Carrier frequency): 2-15 kHz.
Braking (DBr): Built-in braking transistor for 125% Torque x 10 seconds every 100 seconds to 750 Ohm minimum external resistor (not supplied). Recommended resistor 190 Ohms 80W - see the Resistor options linked below or use the 'Which Resistor' button on this page. (Does not have to be used; available if required)
