Pure Sine Wave Inverter for Telecom

タイトルまたは説明

1.Introduction: a) With micro-CPU control, good designing and reliability are the advantages.  b) good compatibility, built-in by-pass switch, high overload feature for reliable and continuous power supply.  c) AC power type and DC power type: AC power type means the city power supply is main when the city power is normal, when city power is off, inverter comes into work state.   DC power type means the inverter power supply is main when the city power is normal, when inverter power is off, city power comes into work state automatically.  d) With the excellent designing, can be auto switched to bypass on the running state, its easy to maintain and replace the battery without effecting load power supply. This function is very suitable for the communication station in which there is no person on duty.  e) support network communication system, power working state can be monitored by the supervision software.  2.  Features 1)      SET-IVS***0 series inverter is the intelligent power inverter, using intelligent microcomputer CPU control technology, the control circuit is simple, reliable, and fast response to changes in the external environment; 2)      SET-IVS***0 series inverter adopting SPWM technology, the output is pure sine-wave with stabilized voltage and frequency, filtering noise and low distortion; 3)      The SET –IVS***0 series inverter has strong load capacity, good load compatibility, built-in bypass switch, which improve the continuity and reliability of the inverter power supply; 4)      SET-IVS***0 series inverter DC adopts advanced reflected noise suppression technology, without interfering with other communication devices which shared DC power, and AC use multiple filtering technology to eliminate mains interference, which meet the application needs of using main AC power; 5)      SET-IVS***0 series inverter has 2 working types: AC power type and DC power type (It can be modified via LCD panel or communication background software); (1) AC power type means the city power supply is main when the city power is normal, when city power off, inverter comes into work state; (2) DC power type means the inverter power supply is main when the city power is normal, when inverter power is off, city power comes into work state automatically; 6)      With the excellent design, SET-IVS***0 series inverter can be automatically switched to bypass on the running state. It’s easy to maintain and replace the battery without effecting load power supply; 7)      In case battery voltage is high/low or overload, the inverter will shut off. When battery voltage returns to normal, the inverter will automatically switch on; when overload was eliminated, the inverter will also automatically switch on. This feature is especially suitable for unattended communication base stations; 8)      SET-IVS***0 series inverter with LCD display, users can see the data anytime. LCD screen uses ***2B, **2 * *2 dot matrix, blue background, silver-white subtitles; 9)      SET-IVS***0 Series Inverter support AC power on, in case of DC power fault conditions; *0)    SET-IVS***0 series inverter can support network communication system, power working state can be monitored by the supervision software (optional); *1) SET-IVS***0 series inverter supports TCP / IP protocol functions. It uses monitoring software  to remote control single / multiple inverters via Ethernet(optional); *2) SET-IVS***0 series inverter provides three sets of passive dry contacts (with separate dry contact interface), respectively for the DC failure (1,2 pin), AC failure (5,6 pin) and AC output failure (3,4 pin) alarms.
