LINEAR AC SENSOR & OVER-CURRENT PROTECTOR
User Guide for SRCN-C253
Product Description
This module is used to measure and monitor current consumption by utilizing electromagnetic current transformer technology. A voltage output is
produced in direct proportion to the measured current. If the current exceeds a preset value, the relay on the module is activated. Uses include
building automation and facility management systems, where acquiring information on energy usage can lead to increased efficiency. They can also
detect equipment issues and help prevent damage by detecting over-current and/or short-circuit conditions.
Features
Integrated delay timer
Low power consumption
CT technology
High accuracy, ±3% of measured range
Relay output with adjustable time settings
35 mm DIN rail or board mount
Applications
Building and facilities management
HVAC
Electric fans
Electric pumps
Devices requiring over-current & short-circuit protection

  • Page 3 Board Mount Mount the PCB to the enclosure with screws. Mounting hole diameter is 3mm. Notes The potentiometer on the module is used for factory setting. All the modules have been set during manufacturing process. Do not adjust the potentiometer by yourself. After long term operation, if the error exceeds the accuracy, see correction method to set this. The modules are tested with pure resistance loads when they leave the factory.
