Safety Relief ValveVariable Frequency Drive – AC (HydroDriveTM)
The HydroDriveTM AC Variable Frequency Drive is a variable speed control in a NEMA-4X / IP-65 washdown, watertight enclosure. It is designed to operate 208-230 Volt 3-phase AC induction motors through 3.6 Amps RMS. The sine wave coded Pulse Width Modulated (PWM) output operates at a frequency of 16Hz which provides high torque and high efficiency at a low noise level.
Standard Features:
Motor Overload Protection** 200% Starting Torque Electronic Inrush Current Limit Short Circuit Protection Regeneration Protection Slip Compensation with Boost Ride Through Power Interruptions Diagnostic LEDs 100% Holding Torque at 0 RPM Barrier Terminal Block NEMA-4X / IP-65 EnclosureNotes: **UL approved as an electronic overload protector for motors.
