• Connecting the input to a circuit, which is subject to a
maximum transient rating of 1500 V.
CB Scheme is available.
The converters are subject to manufacturing surveillance in
accordance with the above mentioned standards and with ISO
9001:2000.
(max. 0.1 Ω) and the electric strength test (table 19) are
performed in the factory as routine tests in accordance with EN
50116 and IEC/EN 60950-1, and should not be repeated in the
field. Power-One will not honor any warranty claims resulting
from electric strength field tests.
Safety of Operator-Accessible Output Circuits
Railway Applications
The Q Series converters have been designed by observing the
railway standards EN 50155, EN 50121-3-2, and EN 50121-4.
All boards are coated with a protective lacquer.
The converters comply with class S1 of the fire protection
standard E DIN 5510-2 (Oct. 2007).
Isolation and Protective Earth
The test of the resistance of the protective earthing circuit
If the output circuit of a DC-DC converter is operator-
accessible, it shall be an SELV circuit according to IEC 60950.
Table 21 shows some possible installation configurations,
compliance with which causes the output circuit of the DC-DC
converter to be SELV up to a configured output voltage (sum of
nominal voltages, if in series configuration) of 35 V.
However, it is the sole responsibility of the installer to ensure
the compliance with the relevant and applicable safety
regulations.
Description of Options
Option P: Output Voltage Adjustment
Option P provides a built-in multi-turn potentiometer, which
allows an output voltage adjustment of ±10% of V_{o nom}. The
potentiometer is accessible through a hole in the front cover.
With double-output models, both outputs are affected by the
potentiometer. If converters are parallel-connected, their in-
dividual output voltage should be set within a tolerance of ±1%.
If V_o is set higher than V_{o nom}, the output currents should be
