Features
- UL 61800-5-1 Listed: Tested to the new UL standard to be implemented in 2020.
- Microprocessor based: Allows custom programming for OEM’s.
- NEMA 4X Plastic Enclosure: Plastic corrosion resistant weatherproof enclosure that protects against dirt and splashing.
- Control a variety of motors: 3-phase induction motors, single-phase permanent split capacitor (PSC), shaded pole, and synchronous motors.
- Doubler mode: Can double a 115 VAC line to run a 230 VAC motor.
- Isolated inputs: Accepts floating or grounded signals 0 ± 5 VDC, 0 ± 10 VDC or 4-20 mA.
- Diagnostic LED: LEDs for power and status (undervoltage, overvoltage, short circuit/current trip, overheating warning/trip).
- Thermally protects: Drive recognizes when overheated as a result of overload. It first flashes a warning code on the status LED and will eventually trip if the condition persists.
- Stopping modes: User can use DC Injection braking, decelerate, or coast the motor to a stop.
- Dump circuitry: Internal circuitry for the hookup of an external dump resistor.
- Quadrature encoder option: For OEM applications, the drive can be programmed to follow quadrature encoder feedback without any circuitry changes.
