QT40.241, QT40.242
Q-Series
24V, 40A, THREE PHASE INPUT
10. REMOTE CONTROL OF OUTPUT VOLTAGE
The shut-down input can also be used to remotely adjust the output voltage between typically 22Vdc and 28Vdc. All
other functions of shut-down input remain the same.
The control voltage is referenced to the main ground (negative output voltage)
