Online Double Conversion UPS systems are ideal for the protection of the mission critical processes with its transformer based architecture. The inverter topology uses 3 full-bridge, 6 IGBT modules switching at 20kHz frequency with ideal output isolation transformer. It is reliable, easy to install, control and use.
Battery Charger is thyristor controlled AC/DC rectifier with automatic constant voltage and constant current ability. Input is fully isolated with isolation transformer. DC output is filtered by L/C, so DC ripple at full load always lower than 1% to increase battery life. The Charger has a modular design to provide service and maintenance simplicity.
Servo Stabilizers are micro-controlled with pulse width modulation controlled servo motors. Each phase is regulated separately thus unbalanced phase voltages regulated at optimum level.
Static Stabilizers are micro-controlled with isolated gate drive switching at zero current, increasing the stability without any voltage and current distortion.
Electronic pf Corrector provides inductive and capacitive compensation with semiconductor architecture. It has excellent correction with 20ms response time. The unit is able to work on small loads with its 32 step capacitive and minimum 2 inductive correction capability. Harmonic suppression is sustained through harmonic filters.
Off-Grid Inverter topology uses 3 full-bridge, 6 IGBT modules switching at 20kHz frequency with ideal output isolation transformer. The output waveform has no distortion for neither non-linear nor reactive loads thanks to this architecture. Ideal for telecommunication and alternative energy applications.
