PSL Series Extended Data Sheet
Positive Switching Regulators (Benign)
REV. APR 5, 2004
Page 8 of 10
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 500 V
The switching regulators are subject to manufacturing sur-
veillance in accordance with the above mentioned UL and
CSA and with ISO 9001 standards.
Isolation
Electric strength test voltage between input interconnected
with output against case: 500 VDC, 1 s.
This test is performed in the factory as routine test in
accordance with EN50116, 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.

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.
However, it is the sole responsibility of the installer or user
to assure the compliance with the relevant and applicable
safety regulations.
