TRS®
Single-phase uninterruptible power supply
Highly functionalization of TRS® TYPE!
Silent demonstration with state-of-the-art UPST with synchronous switching function using Korea’s first IGBT device
overview
This product is an uninterruptible power supply TRS series with synchronous switching supply, and it is an inverter control method using IGBT, a state-of-the-art device. The inverter control configuration has a frequency control range of 20kHz or more, and it is a state-of-the-art circuit that has a synchronous switchover function in the event of a fault or an overload and an abnormality in the load (withstands the load short), and has a function of shut-down if the short of the load is not canceled even in this state.
This control method has been a problem of other types of UPSs, such as the synchronous switching function · Noise · Instantaneous blackouts · Low efficiency · It is a breakthrough product that completely improves unstable voltages.
feature
This UPS is divided into TRS100, TRS502, TRS701, and TRS800 types.
The configuration consists of a converter, battery charger, inverter, filter, base driver, static switch, and main control PCB, and the PWM control range is more than 20kHz, and there is almost no noise, and the efficiency is high due to the SMPS-type design of the live part, and there is a static function in high-frequency PWM control. It has the characteristics of constant voltage,
sine wave, and constant frequency in normal operation, and the LED is indicated in case of fault, and the cooling FAN operates according to the state of temperature. The
front panel is divided into Digital Type, LCD (Micro Processor) Type, and FND Type according to the user’s convenience. In addition, it is small in size and produces almost no noise compared to the size of the same capacity, so it is easy to install even in small places.

Protection of TRS Type
Input overvoltage and undervoltage protection characteristics
– Buzzer alarm (cuts off input voltage, protects the instrument)
Output overcurrent protection characteristic
– Static operation over 120% of the rated output current to switch by pass
– Inverter transfer at By pass at normal load with rated output current of 100% or less
Temperature protection
– In the event of an overtemperature due to an abnormality in the FAN function, the power supply from the inverter to the By Pass
– When the overtemperature occurs above 80°C
in the peninsula stay, the power supply from the inverter to the By Pass
Battery protection
– SMPS configuration for improved precision
– constant voltage · Constant current charging prevents overcharging
– DC low monitoring device prevents over-discharge
Output overvoltage and undervoltage protection characteristics
– When the rated voltage fluctuates by more than ±10% due to failure or abnormality of the inverter unit, it is switched by pass
Remote derivation using DIAL MODEM communication
feature
Remote control and monitoring function – A function to monitor and control the
operation status of the UPS using a PC with a monitoring function using RS232/C
– A function to monitor the UPS
