1. This product is not designed for use in critical life support systems, equipment
used in hazardous environment, nuclear control systems or other such
applications which necessitate specific safety and regulatory standards other
the ones listed in this datasheet.
Over-load
protection
Protection type:
105% to 150% maximum rating, auto-recovery
2. Output connector options: Z=T ( Terminal block type, pitch 8.25mm) or Z=M (
Mini-fit type, pitch 4.2mm) or Z=C ( Connector type, pitch=3.96mm ).
3. All models are equiped with 5Vsb & 12V fan outputs.
4. Ripple and noise are measured at oscilloscope 20MHz bandwidth by a 47uF elec-
trolytic capacitor and a 0.1uF ceramic capacitor in parallel at output connector.
