DC/DC Insulated converters
output power 120 W
• DC wide range input
•
Short circuit, overload, over temperature protection
• Compact design
NOTES BLOCK DIAGRAM
The depth dimension includes the terminal blocks and the DIN
clamp.
(1) Inrush current is measured with input supplied by a battery;
the current peak vary depending on the internal impedance of
the current source and depending on cables and connections
resistance.
(2) Over 50°C (122°F) apply a derating -3 W/°C, max 60°C
(3) According to EN60950 insulation tests on input side must be
made only with DC instruments.
