Figure 4.17 Electrical isolation concept, BG5 and BG6a
4.6 Electrical isolation concept
The control electronics with their logic (µP), the inputs and outputs, are electrically
isolated from the power section (power supply/DC link). All control connections are
designed as safety extra low voltage/protective extra low voltage (SELV/PELV) circuits
and are only allowed to be operated with 5 V to 50 V as per the relevant specification.
This provides reliable protection against electric shock on the control side. The
control electronics therefore require a separate control supply that corresponds to the
requirements of a SELV/PELV.
The overview opposite shows the potential references for the individual connections in
detail. This concept also delivers higher operational safety and reliability of the supply
unit.
SELV = Safety Extra Low Voltage
PELV = Protective Extra Low Voltage
NOTe:
The terminal X5 (for KTY on the step-up choke) represents a special case in
relation to insulation and isolation.
The temperature sensor for the step-up choke must be designed as a minimum
with a basic insulation in relation to the choke winding as per EN61800-5-1.
