1.15. Digital Inputs
IN1: Enable/Disable
This input serves as the primary Enable / Disable logic-switch of the
rectifying bridge.
In order to activate the rectifying bridge of the Tambourine 100,
and maintain it in operation, the IN1 input must be kept energized.
Whenever this input is disabled, the main bridge is being shut
down and the DC BUS output voltage is diminished to zero.
IN2 : VDCBUS Discharge
Whenever there is an applicative need in an immediate-discharge
of the DC BUS voltage, upon any AC failure – then, this input must
be kept energized.
When AC loss event occurs (either temporary or permanent), this
input activates the shunt regulator, for draining the voltage from
the DCBUS capacitors.
