1SU21003 Reliance

Indications
• DC bus voltage: left LED lights when UDC > 50 V
• braking current : right LED lights when IB > 0
Switched output S1-2 (UDC > 50V)
Wearless transistor switch between terminals 1 (-) and 2 (+)
• S1-2 is closed, when UDC > 50 V and IB = 0
• S1-2 is open, when UDC > 50V and IB > 0, or when UDC < 50 V.
As shown in figure 2-4, switch S1-2 is closed after charging of the DC bus, at motor stand still or in
motoring operation mode.
