Description
The BRPMC701 rail-mountable RPM controller, is designed to control the speed of single-phase AC motors up to 5A/230VAC. The unit operates on the principle of ‘phase angle control from 25 to 180 deg., adjusted by a front-panel thumbwheel and applied to an internal power triac. BRPMC701 can switch up to 500 VA AC motors of fans or other industrial appliances, connected to the device output. A ‘softstart’ option allows the motor to reach gradually the preadjusted speed, and a ‘load-current sensing’ option can be used for keeping the motor speed relatively constant and independent on the load.Thanks to their reliability and simplicity, the BRPMC701 controllers can be widely applicable in applications requiring low-cost AC-motor speed control.
