Single Phase : SB rack type
Sag-Backup(SB Series)
Rack Mount Type (EIA:19 inch rack type)
Voltage sag is common failure of very short period of time of voltage drop/disturbance caused by grid change duirng lightning or tight demand of electricity which affect machine’s oepration. SB is a voltage sag compensator to solove the problem for customer continuous oepration. SB rack type is small capacity and suitable for back up control circuit of machines.
Key benefits
– The best solution for voltage sags (short period voltage drop and interruption)
– 10 years maintenance free design (No part replacement needed)
– Superior TCO (Total Cost of Ownership)
– Uninterruptable compensation (response time within 3 msec)
– Smaller footprint and lighter weight
Key features
– High efficiency due to Off-line circuit configuration (Efficiency more than 95%)
– Higher inrush current withstand SCR requires no external bypass circuit*1
– No stoppage/interruption by internal bypass circuit when major failure occur
– Conformity with SEMI-F47
Typical applications
– Semiconductor / LCD / Film / Food and beverage / Pharmaceuticals
‐ Conveyer / Precision processing equipment / Injection machine / Robot / Contactor
