LCR Electronics is launching the EC102 and EC103 series of 'smart' digital triac (triode for alternating current) closed-loop control boards that enable motor speed regulation down to +/-2 per cent. The boards' exceptional precision, combined with their low cost, makes both series suitable for commercial and consumer power tools, as well as small appliances such as blenders and mixers, or other applications where 'set and forget' pushbutton control is used.
To achieve precise speed regulation, the EC102 and EC103 can accept sensor feedback in variable voltage or variable frequency types, as set at the factory. The control method for both boards includes a soft-start that is optimised for use with universal motors to prolong the life of the end products.
Unlike the EC102 that uses a power system related to power line voltage, the inputs on the EC103 are isolated from the AC power, thereby simplifying the interface to remote equipment since fewer isolation points are needed for remote sources, such as a PLC.
Both boards feature a bidirectional electronic switch that conducts current in either direction when triggered. The closed-loop design allows users to regulate speed selection with variable inputs, such as a knob or lever, or presets, including buttons and switches. High-visibility LEDs indicate board power and status. Control inputs include a potentiometer for variable voltage applications or a tact switch, which is especially useful in lighting control applications.
With an operating temperature range from -40 to 85 degrees C and optional conformal coating, both series perform well in hot, humid and dusty environments as well as in lower-temperature applications.
The 12A maximum current load on the EC102 and EC103 is upgradeable, depending on application requirements. RoHS compliance and optional EMI filtered units are also available. Input voltage is 120/240V AC.
LCR's expertise in customization and rapid prototyping enables the extremely quick delivery of both the EC102 and EC103 boards for custom applications. As with many motor control boards from LCR, the EC102 and EC103 series are standard products with features and design elements that can be easily tailored to meet specific application requirements.
Pricing for 1000 EC102 units starts at $8 per unit. Pricing for 1000 EC103 units starts at $10 per unit. Delivery is 8-12 weeks.
