USVF-24D | US Electric Single Phase To Three Phase Inverter 1 Hp 230V

• 1 HP; MAX 4 Output amps @ 230 Volt
• Operates standard 208/230V 3-phase AC motors, with 230V  input single phase
• Power Start provides more than 200% starting torque
• Speed potentionmeter (pot) provided
• Jumper selections: Forward-stop-reverse/Enable-automatic-manual

Not Recommended for use on air compressors. Speed potentiometer must be connected or the motor will not spin, without the pot the speed is set at zero and you will burn the motor up. “KBVF” Frequency Drive. A Low Cost, full featured, Motor Control / Frequency Drive. with 100% power output. Single phase input – Three phase output. If you have been to a used equipment auction and purchased a mill, lathe, drill press or other piece machinery with a three phase motor and are looking for a low cost solution to power it with single phase power. This may be your low cost solution. Unlike some of the electronic phase inverters that only output 2/3 of the power, this unit puts out 100% 3 phase power with 200% starting torque. You will need to eliminate any other motor switches. You will connect the motor directly to the 3 terminals on the converter. Otherwise the contacts from the old motor starter will allow feedback to the control that will damage the unit. The KB control becomes the motor starter. The unit should be powered through an electric power disconnect. When selecting drive size the motor amps cannot exceed the rated output amps of the control. Standard Features: Operates standard 208/230 VAC 3-phase AC motors, with 230 VAC input single phase. Power Start provides more than 200% starting torque. 30:1 speed range with full motor torque (Speed potentionmeter (pot) provided). (Motor should be inverter rated if using speed control feature). Controls 50hz and 60hz motors with a convenient jumper selection. Sinewave coded PWM-provides high motor torque and efficient operation. 16 khz switching frequency-provides quite motor operations. Motor overload protection. Jumper selections: Forward-stop-reverse/Enable-automatic-manual. You can use a 3-position toggle switch. Start 0-60,0-120, 0-50hz.Trimpot adjustments: Minimum Speed-min, Maximum Speed-Max. Important Application Information: Most fan-cooled (TEFC) 3-phase motors will overheat. if used with an inverter beyond a limited speed range at full rated torque. Therefore, it is necessary to reduce motor load as speed is decreased.Attention: Your motor amps cannot exceed the rated output amps of the converter. Note: Motor can not be run through contacts. Motor to be wired directly to controller. You will need to soldier leads to the potentiometer and connect it to the control.
