Norristown, Pa. April 2009 – LCR Electronics, a leading manufacturer of EMI filters, electronic products as well as high-end enclosures for military, telecom and commercial applications, now offers 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%.
The boards’ exceptional precision combined with their low cost makes both series beneficial to many commercial and consumer power tools as well as small appliances such as blenders and mixers, or wherever “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 optimized 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, simplifying the interface to remote equipment since less 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. Highly visible LEDs indicate board power and status. Control inputs include a potentiometer for variable voltage applications or a tact switch, especially useful in lighting control applications.
With an operating temperature range from -40°C to +85°C (-40°F to +185°F) and optional conformal coating, both series perform well in hot, humid and dusty environments as well as in lower temperature applications.
The 12 A 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 120/240 VAC.
LCR’s expertise in customization and rapid prototyping enables the extremely quick delivery of both the EC102 and EC103 boards for unique and specific applications. As with many motor control boards provided by LCR, the EC102 and EC103 series are a standard product with features and design elements easily tailored to meet specific application requirements.
Pricing for 1,000 EC102 units starts at $8 per unit. Pricing for 1,000 EC103 units starts at $10 per unit. Delivery is 8 -12 weeks ARO.
