Analog Front End for Motor Electronic Overload Relays with Enhanced Current Range
TIDA-00191: This reference design is the analog front end (AFE) for an electronic overload relay, used for monitoring and protecting motors from overcurrent or undercurrent events. It is an ideal tool for developers creating overload relays for sensitive AC motors in industrial applications. This programmable gain amplifier (PGA) based analog front end is intended to be an easy evaluation platform for an accurate, industry-leading 10:1 full load ampere (FLA) range and is repeatable over a -10 to +70°C temperature range.
Zero drift PGA based Analog Front End Design for Circuit Breakers (ACB/MCCB-ETU)
TIDA-00130: This reference design is intended for use in molded case circuit breakers (MCCB) electronic trip units. The programmable gain amplifier based design acts as the current monitoring for over-current earth fault relays. Utilizing a zero drift programmable amplifier, this design provides a ±10 % pick-up (A) accuracy and time delay (s) accuracy of 0 to -20%. Additionally, this solution was designed to handle harsh environment conditions by including features such as ambient insensitivity from -10 to 70 ⁰C and high electromagnetic immunity. Finally the analog front end of this design interfaces seemlessly with the TI MSP430 MCU for quicker evaluation and faster time-to-market.
Self or Dual-Powered Supply for Protection Relay, MCCBs & ACBs Ref Design
TIDA-00229: This power supply solution for Protection Relays & MCCBs handles both the current input from a Current Transformer (CT) or input from an Auxillary (Aux) source. The "self-powered" capability comes from being able to harness the power available in the grid through the CT. The flexibility of this solution's "dual-power" input comes from the ability to also handle the Aux input - which is often a battery source.
