Techmartsupp Voltage Switch Plus (TVS+) AC Switch

Application:

Techmartsupp voltage switch (TVS+) is designed for the protection of single phase air conditioners with rated voltage of 220V and
frequency of 50 Hz. The main purpose of TVS+ is to protect the A/C unit from unallowable voltage drops, fluctuations in the main
power circuit, overload, and automatic turning ON the unit after the voltage recover and return to normal values with the user defined
time delay. Total maximum power that could be connected to TVS+ is 4.0kw (20A AC-1).
TVS+ contains built-in high frequency filter which additionally protects air conditioners from impulse interruptions.
On the front panel there is a digital display indicating the acting value of input voltage during operation and when pressing the
setting keys it shows the precise parameter values adjusted by user. Additional LED indicator “LOAD’’ shows the ON/OFF state
of the output relay (ON/OFF state for the connected equipment).

General Description:

TVS+ has three main functional states:
NORMAL OPERATION MODE: In this mode, if the controlled voltage within range and the auto reclosing time after the voltage
interruption has expired, TVS+ will keep on working in this mode. Equipment in this mode is connected to the power supply and turned
ON, LED light green and instantaneous voltage value is indicated on the digital display.

  • VOLTAGE FAULT ALARM MODE: If the voltage exceeds the preset threshold, the TVS+ switches load off and the LED light RED. If
    the fault is voltage related, the digital display will blink continuously showing the value of the unacceptable voltage. When the voltage is
    restored within the pre-set range, voltage is restored after the expiration of the delay time and the LED turns GREEN.
  • AUTO RECLOSING TIME MODE: In this mode, TVS+ resumes back to its normal operation mode when the voltage parameters return
    back to normal values on the digital display of the switch, the remaining time of auto- reclosing is display in seconds.
  • OVERLOAD TRIP MODE: This protective mode is activated when load current exceeds 20A. The circuit breaker (switch) trips off to
    disconnect the input of the relay. Reset after a technical person has been called to investigate the actual cause of the trip.

Programming:

  • MAXIMUM VOLTAGE: Press 7 for 3s, it’ll enter the maximum voltage adjust mode and display "S-H", release the
    key and press again (within 3s) to decrease voltage in steps of 5V; press 6 to increase voltage in steps of 5V between 230-
    280 volts . Release both buttons for 3 Sec and the set value will be remembered.
  • MINIMUM VOLTAGE: Press 7 for 3s, it will enter program mode, and display "S-H" While still holding 7, press 6
    once, it’ll enter the minimum voltage adjust mode and at this point you’ll see "S-L”, Release both buttons and press 7 again
    (within 3s) to decrease voltage in steps of 5V; or Press 6 to increase voltage in steps of 5V between 140-230 Volts. . Release
    both buttons for 3 Sec and the set value will be remembered.
  • DELAY TIME: Press 7 for 3s, it will enter program mode, and display: "S-H" While still holding 7, press 6 twice, it’ll
    enter the time adjust mode and at this point you’ll see "S-t” , Release the 2 keys and press 6 again (within 3s) to increase time
    in step of 5s (between 0-60s) or step of 30s (between 60-900s), and press 7 to decrease time in step of 5s (between 0-60s) or
    step of 30s (between 60-900s). . Release both buttons for 3 Sec and the set value will be remembered.
    In a case of overload (i.e current >20A) the switch will trip off automatically and after the problem is solved, manual press
    the switch to put it on and reset it.

NOTE: When the input voltage is within the pre-set value and the delay time has expired, the output loads is energized and
the LED light is GREEN, otherwise, the LED light RED and the voltage parameter continue to blink.
