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.
A minimal wiring scheme is shown in the gure below. The main point is that the POWER_ON
input is the one that should be used to turn the electric device ON or OFF. In particular, shut-down
by disconnecting VIN_N or VIN_P may in some circumstances result in the corruption of
the parameters of the electric device or other data.
Figure 34. Example of the minimum connections
The switch (SW1) is used to turn the converter on and off. VIN_P and VIN_N are continuously
connected to the power supply. There is an internal pull-down in the POWER_ON input. Use
appropriate fuse (F1) for protection. See values and information for fuse selection from the
product data sheets.
