Toshiba G9000 specification

Guide Specification – 3-Phase Static Uninterruptible Power Supply

If the bypass source is beyond the conditions stated below, interrupted transfer shall be made upon detection of a fault condition.

Bypass voltage greater than + 10%, -10% from the UPS rated output voltage. Bypass frequency greater than + 1 Hz from the UPS rated output frequency.

5.4.2Overload Capacity in Bypass:

Continuous duty	: 125% of the system rated capacity
Overload duty	: 1000% of ampere rating for 1 cycle.

5.4.3Retry function:

When an internal warning has been detected, power flow will automatically switch from the main circuit (inverter) to the bypass circuit without interruption to the load. If the internal warning is cleared, UPS will automatically switch the power flow from the bypass circuit to the main circuit (inverter) without interruption.
