LOW VOLTAGE DC Drives - 1Q Chassis AC Input
LVA Series 1Q PWM Adjustable Speed Drive for Low Voltage PMDC Brushed Motors The LVA Series of variable speed drives provide exceptional performance for your 12 and 24 VDC fractional horsepower motors. Packaged in a compact footprint, these user friendly drives are available with a unique AC or DC input voltage. The auto ranging unipolar power supply allows standard low voltage drive to accepts inputs from any AC voltage source ranging from 8 to 24 VAC, or DC voltage between 10 to 36 VDC. The LVA Series is ideal for cost sensitive variable speed applications requiring outstanding performance, and cooler, quieter motor operation from low voltage DC motors.
