This document describes the VEVOR Digital Phase Shifter, a device designed to convert single-phase power into three-phase power for motors.
Function Description
The VEVOR Digital Phase Shifter (DPS) is designed to operate 3-phase 220-240V motors from a single-phase 220-240V power supply. It generates three-phase voltages when the motor is running. The device is intended for use with one motor that meets its specifications. While it can potentially be used for multiple motors if their start and stop times are the same, it is primarily designed for a single motor application. The DPS helps in achieving higher efficiency, especially when its capacity is one step above the motor's capacity.
Important Technical Specifications
The Digital Phase Shifter is available in three models: CPS-5HP, CPS-7.5HP, and CPS-10HP, each corresponding to different motor capacities and current ratings.
Model Specifications:
-
CPS-5HP:
- Capacity: 4-5HP
- Current (A): 15
- Frequency (Hz): 50/60
- Dimension: 250135152mm
-
CPS-7.5HP:
- Capacity: 5-7.5HP
- Current (A): 23
- Frequency (Hz): 50/60
- Dimension: 250135152mm
-
CPS-10HP:
- Capacity: 7.5-10HP
- Current (A): 30
- Frequency (Hz): 50/60
- Dimension: 250135152mm
All models operate with a 1-phase 220-240V~ input and provide a 3-phase 220-240V~ output. The product specifications are subject to change without prior notice to improve quality.
Usage Features
Installation and Connection:
- The DPS should only be used for 3-phase 220-240V motors.
- Install a safety circuit breaker at the input terminal as the DPS itself does not have a protection device.
- Connect only U and W lines for control wires of electronic switches, brakes, or magnetic contactors.
- Only 1 phase of motor brake is allowed; 3-phase brakes will not work.
- Ensure the magnetic control line is connected to the U and W positions of the DPS output.
Operation and Efficiency:
- Three-phase voltages are output only when the motor is running. When the motor is not running, only single-phase output is normal.
- Initially, there might be voltage and current imbalances, but these will balance when the load exceeds 50%. This is part of the process of converting single-phase to three-phase.
- For optimal efficiency (90-95%), it is recommended to use a DPS model that is one step above your motor's capacity. Using a DPS with the same capacity as the motor typically yields 65-70% efficiency.
- Never use a DPS model that does not meet the motor capacity, as this can cause motor overheating.
- Avoid using a DPS with a capacity two levels higher than the rated motor capacity, as this may lead to overheating or other issues.
Troubleshooting Common Issues:
- Motor runs well then breaker trips: Check the breaker capacity. It should be twice the motor's rated current (e.g., for a 15A motor, use a 30A breaker).
- DPS power checked, but motor not running: Verify DPS and motor connections, especially ensuring magnetic control lines are connected to U and W of the DPS output.
- Voltages and current too high: This can occur if the DPS capacity is too large for the motor. Also, confirm that only one DPS is used per motor.
- DPS LED power not on: Check the input power and contact customer support if the issue persists.
- Motor runs well then stops: Check the magnet switch connection, overload capacity, and breaker capacity. Also, check for general overload.
- Motor slows down/runs unevenly: Check the motor's load volume. Use a load less than 85% of the motor's capacity to prevent overcurrent due to overloading.
- Excessive noise during operation: Check the DPS and motor capacity. Noise and heat can be generated if the DPS specification is higher than appropriate for the motor.
- High motor output current/overheating: Ensure motor and DPS capacities are properly selected (e.g., a 10HP motor with MY-PS-15, or a 15HP motor with MY-PS-20).
- Availability for other applications: The DPS can be used for sunbeds, welders, ovens, and tanning machines, but it may be slightly less efficient than when used with motors. Contact the head office for specific guidance.
Safety Precautions:
- Always read the instruction manual carefully before use to reduce the risk of injury.
- Immediately cut off power in case of abnormality to prevent electric shock.
- Do not move or install the product when current is flowing or exposed, as this poses a risk of fire or electric shock.
- Always cut off the power switch during power failure. Automatic restarts upon power restoration can cause unexpected accidents.
- Do not disassemble, assemble, or modify the DPS.
- If smoke, strange smell, or noise is detected, immediately turn off the switch, disconnect the plug, and contact the service center.
- Continued use under such conditions may cause fire or electric shock.
