An Electronic Trip Unit (ETU) is programmable device which measures and times current flowing through the low voltage circuit breaker (MCCB and ACB) and initiates a trip signal when appropriate. As modern low voltage power distribution system requires more communication/intelligent function to realize a higher level system features (e.g. zone Interlocking), a micro-processor based electronic controller unit is becoming more and more popular in the low voltage switchgear/breaker system. ADI offers a simple system solution.
ADP2450 from Analog Devices is an ASSP specially designed for low voltage circuit breaker like MCCB and ACB
It includes a low power shunt boost controller to convert a current source (output from current transformer) into voltage source and a buck regulator which can effective regulate out a 3.3V/5V/Adj power supply
4x programmable PGAs with 15 different gain setting option and one general purpose OPAMP have been integrated into the ADP2450
4x threshold value programmable analog trip unit inside, that support both single coil and dual coil user case
Simplify ETU system design that only use ADP2450, low power MCU and interface
