Chapter 2. Product Introduction
Characteristics:
There are two operation modes offered by the Maintenance Bypass Switch:
One is UPS Mode(UPS Available) and the other is Utility Mode(Maintenance
Bypass).
1. UPS MODE (UPS available): When the MTBS works on the UPS mode, the
UPS is supplied energy from the Utility, then the UPS feeds it to the load
connected.
Figure 1: UPS mode of operation
2. UTILITY MODE(Maintenance bypass)When the MTBS works on the Utility
Mode, the load connected is supplied energy from the Utility directly, then the
UPS can be turned off. No affection of the connected load will occur while
maintenance or repair.
