Compensation Load Line Voltage Drop (Sense ++/--) battery charger operation mode
Remote Sensing as a battery charger
If the HSEUiREG power supply unit is used as a battery charger, it is recommended to refrain from sensing. It
can lead to severe damage to the power supply, if the polarity of the sense line is confused (field experience:
such error often occurs when system service is required, e.g., when the batteries are changed). If it is
necessary to use sensing, proceed as described in the figure below. Proven approaches are 250mA for the
fuses and 3...5A load capacity of diodes.
WARNING!
Reverse polarity of the sense lines can cause damages to the power supply unit.
External Shutdown (SD)
The power supply is set to the Shutdown mode, when the
control input is either shorted via a relay contact, a switch
contact or an NPN transistor with open collector (voltage drop
<1V, current typ. 2mA).
If the shutdown repeals the power supply starts again.
Using the soft-start, the current and the voltage rises within
continuously to the default set values.
Power-OK Relay (DC Power Good)
The alarm signal DC OK has potential-free relay contacts. The contacts are closed (relay
coil is energized) when the power output is active. In shut dwon mode (SD) the contacts
are closed.
The contacts are open when the power output is inhibited by OT or low AC supply voltage
at the AC inputs. Contact load (resistive load): 30Vdc/1A, 60Vdc/0.3A, 30Vac/0.5A.
Over Voltage Protection (OVP)
If an over-voltage occurs to the output (for example, defective components, external feed voltage), it is followed
by the shutdown of the power output. A periodic restart attempts (ticker operation period 400ms).
Over Temperature Shutdown (OT)
The alarm LED OT lits when the temperature of the power supply is higher than the over-temperature
protection threshold.
