Application:
Cedarberg Static Phase Converters are designed to start motors within a specific horsepower range. Smaller motors may be started one at a time,
once a motor within the converter’s horsepower range is running, provided that the smaller motors are wired into the same circuit.
Cedarberg Rotary Phase Converters are designed to start any motor from fractional horsepower up to the nameplate rating. If the motor on the
equipment is larger than the phase converter’s nameplate rating, a phase converter of the correct size will need to be purchased. Do not attempt to
start a motor that is too large for the converter or damage could occur.
Features:
Instant reversal motors present no problems to these converters. For Series 1B and Series 3 converter installations, we recommend that frequent
reversing not be done for extended periods of time. Our Series 1B and Series 3 units will start more than one machine, as long as each motor is
within the horsepower range of the converter. When multiple three phase motors are on the same circuit and not within the range of the
converter, the following steps must be taken:
- Start the largest motor first. (This motor must be within the converter’s range.)
- While allowing this motor to idle, additional, smaller motors may be started one at a time.
- The motor that is within the range of the Series 3 converter must remain running throughout the duty cycle of the smaller motors. With the
Series 1B converter, the motor that is within the range of the converter may be turned off once the smaller motor is running and up to speed.
- Rotary Phase Converters are capable of starting any motor from fractional horsepower up to their nameplate rating. They are designed to run total horsepower loads up to three times the nameplate rating on Heavy Duty models and up to two times the nameplate rating on Standard Duty models.
Two-speed electric motors can be operated without difficulty, provided both speed ranges lie within the converter’s horsepower range.
Some foreign and special motors require less starting current and therefore may require a static converter one size smaller than normal.
