Instructions for DC use:
a) Use a battery or similar DC source.
For other sources contact PULS
b) Connect +pole to L1 and –pole to L2.
c) Use appropriate external fuses in the + and – lines which
are suitable for the DC-voltage.
d) Connect the PE terminal to a earth wire or to the machine
ground.
e) DC-operation is not included in the UL approval.
Additional testing might be necessary.
5. INPUT INRUSH CURRENT
An active inrush limitation circuit limits the input inrush current after turn-on of the input voltage and after short
input voltage interruptions.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
