The general equation (1) for changing the output
voltage on the standard trim modules is invariant,
but the constants in the equation change due to
different internal design.

Optional Positive Trim (suffix –T)
The -T option units trim up with a resistor from the
TRIM pin to the +Sense pin and trim down with a
resistor from the TRIM pin to the –Sense pin as
shown in the Figure 9.

Notes:
1. When the output voltage is trimmed up, the
output power from the converter must not
exceed its maximum rating. This is
determined by measuring the output voltage
on the output pins, and multiplying it by the
output current.
2. In order to avoid creating apparent load
regulation degradation, it is important that the
trim resistors are connected directly to the
remote sense pins, and not to the load or to
traces going to the load.
3. The HLS30 series converters will trim down
further than the 10% limit. In general, this is
permissible. The user must confirm that the
results are acceptable in his application.
Safety Considerations
The HLS30 series converters feature 1500 Volt
DC isolation from input to output. The input to
output DC resistance is greater than 10MOhm.
These converters are provided with Basic
insulation between input and output circuits
according to all IEC60950 based standards.
Nevertheless, if the system using the converter
needs to receive safety agency approval, certain
rules must be followed in the design of the
system. In particular, all of the creepage and
clearance requirements of the end-use safety
requirements must be observed. These
documents include UL60950, CSA60950-00 and
EN60950, although other additional requirements
may be needed for user’s specific applications.
The HLS30 series converters have no internal
fuse. An external fuse must be provided to
protect the system from catastrophic failure, as
illustrated in Figure 7. The fuse with a rating not
greater than 10A is recommended. The user can
select a lower rating fuse based upon the highest
inrush transient at the maximum input voltage
and the maximum input current of the converter at
the minimum input voltage. Both input traces and
the chassis ground trace (if applicable) must be
capable of conducting a current of 1.5 times the
