Low voltage signals: minimum connections needed for powering the electric device
Minimum wiring and connections
Pin Signal name Description
13
VIN_N
Power supply negative
1
VIN_P
Power supply positive (continuous). Typically 12-24 V, see data sheets.
2
POWER_ON
Power supply positive (from on/off key). Typically the same voltage as VIN_P.
24
STOP_1
Stop input 1. Needs to be pulled up (same range as VIN_P) for the converter to run.
Disconnecting the STOP input or pulling it low externally causes the power semiconductor
switch drivers to be disabled, which makes the converter a diode bridge. Stopping the converter
with one of the STOP inputs causes also a fault, which needs to be cleared before continuing
operation.
3
STOP_2
Stop input 2. Identical to stop input 1. Both need to be pulled up in order to be able to run.
