KB Electronics continues to dominate the fractional to 5-horsepower DC Drive Speed Control market. While DC motors and drives offer the user the ultimate in high performance, small size and low cost, small AC motors and drives are challenging that very concept. Our goal was to develop a line of AC Drives that would and could replace DC controls. Today KB offers you, our customer, AC Drives that match the performance of DC drives but fit within the same footprint or are smaller than their DC counterparts.
Everything you have read about KB products in the past is still true however, a whole new chapter of the future of KB Electronics is being written.
Many of our Penta-Power products contain the patented KBMM current limit circuit, other products feature current feedback loops with motor burnout protection. Our PWM controls are short circuit proof and prevent high speed runaway. KB controls will satisfy your most demanding requirements.
YOUR MOTORS WILL LAST LONGER WITH KB CONTROLS.
Most of today’s motors are of the permanent magnet type. Under certain conditions, such as frequent starting or accidental jam ups, the magnets in these motors can become demagnetized. Demagnetization does not occur instantly but is cumulative with time. This results in a loss of speed and efficiency at rated torque. In fact, most motor manufacturers publish a specification sheet indicating the demagnetization current for their motors.
To eliminate this potential problem, KB’s engineering staff designed and patented the fastest current limit circuit available. It is a high-speed, direct-fed™, anti demagnetization circuit.Your motor will not become demagnetized when using any of our Penta-Power products.
Some Penta-Power controls have built-in motor burnout protection. If the motor should stall or jam, our TCL circuit will shut down the control. For controls without built-in motor burnout protection, we offer an accessory with this capability, our Current Sensing Overload Relay module (KBAP-240D).
