Thyristorized Switching Module

ONLINE’ Make “SmarTSM” is a micro-controller based intelligent Thyristorized Switching Module, especially suitable for switching delta connected power factor capacitors. The module comprises of solid-state Thyristor switch of suitable rating to switch on/off a capacitor bank. The special zero-cross switching circuit switches the capacitor without the electrical stress, avoids starting in-rush current in capacitor and avoids harmonics and power spikes generated during capacitor switching. This enables a fast switching cycle and a smooth and spike-free power quality. Each SmarTSM module has a built-in microcontroller to monitor various parameters and provide protection. Each module has its own heat-sink and temperature controlled cooling fan.
Salient Features:
Modular design Each module is fully integrated with its own heat-sink and cooling fan with temperature control.
Very easy to install. It can be wired like a contactor.
Each module has its own microcontroller with built-in intelligence for monitoring and protection. In addition to capacitor switching function, it has following additional features:
Seven segment LED display for capacitor current, voltage, temperature and error codes.
LED indications for control input/output, fan on, error & display freeze.
Programmable parameters: under/over voltage, over current, over temperature, fan on/off temperature and display scan time. These parameters can be set using built-in 4 keys keypad.
The zero-cross switching ensures a transient free, stress-less switching of the capacitor. It ensures better power quality and long life to capacitors. It also allows capacitor switching without a discharge delay.
Very fast switching every 500 msec
Suitable for switching capacitors, and capacitors with reactors.
Can be switched using APFC relay having either transistor or relay output.
Designed for critical switching application in fluctuating loads.
Protections against under / over Voltage, over current and over temperature.
Two limb Control latest technology trend
No Auxiliary Supply required
Very compact in size ( 280 (H) X 115 (W) X 180 (D) )
