PSL Series Extended Data Sheet
Positive Switching Regulators (Rugged)
REV. APR 26, 2004
Page 11 of 16
Isolation
Electric strength test voltage between input interconnected
with output against case: 1500 VDC, 1 s.
This test is performed in the factory as routine test in
accordance with EN 50116, IEC/EN 60950 and UL 1950
and should not be repeated in the field. Power-One will not
honour any guarantee claims resulting from electric
strength field tests.
Installation Instruction
Installation of the switching regulators must strictly follow
the national safety regulations in compliance with the enclo-
sure, mounting, creepage, clearance, casualty, markings
and segregation requirements of the end-use application.
Check for hazardous voltages before altering any connec-
tions. Connections can be made using fast-on or soldering
technique.
The input and the output circuit are not separated, i.e. the
negative path is internally interconnected!
The units should be connected to a secondary circuit.
Do not open the modules.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also
Safety of
operator accessible output circuit.
Standards and Approvals
All switching regulators are UL recognized according to
UL 1950, UL recognized for Canada to CAN/CSA C22.2
No. 234-M90.
The units have been evaluated for:
Building in
Operational insulation from input/output to case
The use in a pollution degree 2 environment
Connecting the input to a secondary circuit which is sub-
ject to a maximum transient rating of 1500 V
The switching regulators are subject to manufacturing sur-
veillance in accordance with the above mentioned UL and
CSA and with ISO 9001 standards.
Safety of Operator Accessible Output Circuit
If the output circuit of a switching regulator is operator ac-
cessible, it shall be an SELV circuit according to IEC/EN
60950 related safety standards.
The following table shows some possible installation con-
figurations, compliance with which causes the output circuit
of the switching regulator to be an SELV circuit according to
IEC/EN 60950 up to a configured nominal output voltage of
30 V, or 48 V if option C is fitted.
However, it is the sole responsibility of the installer or user
to assure the compliance with the relevant and applicable
safety regulations.
