Low frequency ups 3B Series

3B3 series includes 10-15-20-30-40-60-80-100-120 three-input&three-outpu models, use online double conversion technology (VFI), with output isolation transformer .

Inverter provided the filted, stable, continuous sine wave to the load. Input and output EMI filters greatly increase the load on the AC against interference and surge, even in bypass mode

Due to its outstanding mechanical and electronic design, 3B3 series provide maximum protection to critical network security applications (medical electronics) and industrial applications

Through the monitoring software, it can easily monitor action of UPS, battery back-up time can be extended to several hours by counter.

3B3 series application: industrial process control, servers, local area network (LAN), data center, internet centers, industrial PLC, building back-up power supply, emergency equipment (power supply / alarm), electronic medical equipment, telecommunications equipment.

Performance characteristic:

1,Reliable and stable sine wave output (double conversion online VFI, in line with requirement of  en50091-3 for interference suppression filter)

2, High reliability:  use fourth-generation IGBT power devices and multi-protection technology, full digital control, high output current transient to enable ups to adapt to a variety of loads: transformers, emergency lights, electrical equipment, industrial control equipment, use classical and stable output with isolation transformer structure.

3, Anti-human misoperation design ,manual bypass switch functions, does not require a fixed strictly step to operate, without suddenly power off or damage of UPS.

4, A direct parallel distributed technology to ensure online capacity expansion and system redundancy, up to 6 ring redundancy in a standardized way, the instantaneous value of a significant reduction technology system can reduce parallel circulation.

5, Human friendly interface, easy operation, high-level diagnostic features, multi-language display, 120 events, status, measurement and alarm information.

6,’Economic mode’ function (100/120kva), large machinery to improve efficiency 98%; during certain hours provide ”non-critical load”online interactive technology (VI) directly from the AC supply,this function can be set.

7,Simple installationset the output voltage (phase voltage 200-244), ups can be connected to the various distribution systems (TN-C TN-S TN-CS TT IT), electricity can be 2-way input (rectifier and bypass)

8, Fully automated intelligent battery management: according to the battery discharge curve ,automatic adjust terminal discharge voltage, to avoid setting a fixed value which may cause excessive discharge of the battery; intelligent temperature compensation based on the charging and discharging battery management which can extend battery life more than 50% ,automatically on a regular basis carry out battery self-test to reduce the maintenance work and ensure reliable back-up time of battery; temperature compensation of battery charging characteristics , low ripple (<;1% c10).

9、Smart RS 232 interface, EPO (emergency shutdown) input for remote control of ups shut-down.
