Intelligent static transfer switches - Insta switch, Mega switch - Ensures maximum reliability to critical
loads by eliminating system failures that are caused by power distribution problems.
INTRODUCTION
The INSTA & MEGA switches allows instantaneous
transfer of load between two power sources. It can be
used to ensure complete redundancy of power supply
upto the last piece of wire. It is useful in many applications,
where redundant power supply is available, either from
two UPS systems or one UPS and bypass source.
These switches are comprising of semiconductor
switches, they ensure continuity of power to the load in the
event of failure of one of the power sources. They have
different user selectable parameters and in-built
microprocessor. Typical applications include Data
centers, Call centers, Process control and Automation
etc.

FEATURES
Uses Power Semiconductors as Switching Element
It acts like protective barrier to the load. When power supply
feeding to the load goes beyond the preset limits (Frequency
or voltage) the switch instantly disconnects from load and
protects it.
Independent Micro-controller
Makes it independent of source functioning and its control
scheme. The smart control enables user to select the
priority of source.
Simple & Rugged design
Low component count, giving high level of reliability.
User friendly display & Control
Display provides status of incoming power source and the
condition of static switch.
Exceptional Performance
It is tailored to suit the requirements of different operating
conditions. It tracks the Input Voltage, Phase & Frequency,
Distortion levels at the terminal points. If these parameters
are within the limits then depending upon the priority selection,
it activates the respective switch. This ensures the power
availability to the load
FUNCTION
In a typical connection (see diagram) two different power
sources (UPS, Stabiliser, Power conditioner etc.) are
connected to the critical load through INSTA / MEGA
switch, which will intelligently monitor the power from the
sources. Depending upon the preset limits, it will allow the
power to be passed to the critical load & thus making it as
the best solution for mission critical applications.
MODBUS RS 232 / 485 Interface (optional)
To connect your building Management System (BMS) for
monitoring of all status & alarms
Potential Free contacts (optional)
For remote monitoring of the switch activity
