HLS Series DC-DC Converter Data Sheet
48VDC Input, 30 & 40 Amp Half-Bricks
When the ON/OFF pin is used to achieve remote
control, the user must take care to insure that the pin
reference for the control is really the -Vin pin. The
control signal must not be referenced ahead of EMI
filtering or remotely from the unit. Optically coupling
the information and locating the optical coupler
directly at the module will solve any of these
problems.
Typical Application
Figure 6 shows the recommended connections for
the HLS Series converter.
Note:
If the ON/OFF pin is not used, it can be left floating (positive logic),
or connected to the -Vin pin (negative logic).
Output Voltage Trim
The trim feature allows the user to adjust the output
voltage from the nominal value. This can be used to
compensate distribution drops, perform margining in
production, or accommodate other requirements
when output voltage needs to be adjusted from the
nominal. There are two trim options available in the
HLS Series.
Figure 6. Typical Application of HLS Series
The HLS Series converters do not require any
external components for proper operation. However,
if the distribution of the input voltage to the converter
contains significant inductance, the capacitor C1
may be required to enhance performance of the
converter.
A minimum of a 47µF electrolytic
Negative-Trim (No P/N suffix)
capacitor with the ESR<0.7Ω is recommended for
the HLS Series.
All HLS negative-trim models trim up with a resistor
connected 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 Figure 7.
Refer to the “Inrush Current Control Application
Note” on www.power-one.com for suggestions on
how to limit the magnitude of the inrush current.
For output decoupling we recommend using one
10µF tantalum and one 1µF ceramic capacitors
connected directly across the output pins of the
converter. Note, that the capacitors do not substitute
the filtering required by the load.
Shutdown Feature Description
The ON/OFF pin in the HLS Series converters
functions as a normal soft shutdown. It is referenced
to the –Vin pin (see Figure 6). With positive logic,
when the ON/OFF pin is pulled low, the output is
turned off and the unit goes into a very low input
power mode.
With negative logic, when the
ON/OFF pin is pulled low, the unit is turned on.
An open collector switch is recommended to control
the voltage between the ON/OFF pin and the -Vin
pin of the converter. The ON/OFF pin is pulled up
internally, so no external voltage source is required.
The user should avoid connecting a resistor between
the ON/OFF pin and the +Vin pin.

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 all models (–T, P/N suffix)
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 8.

from the converter must not exceed its maximum rating. This

pins, and multiplying it by the output current.

degradation, it is important that the trim resistors are

Safety Considerations
Thermal Considerations
The HLS Series converters feature 1500 Volt DC
isolation from input to output. The input to output DC
resistance is greater than 10MΩ. 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 HLS Series converters are designed for natural
or forced convection cooling.
The maximum
allowable output power of the converters is
determined by meeting the derating criteria of all
electronic components used in the power supplies.
An example of the derating criteria for the
semiconductor junction temperature is not to exceed
120°C to provide reliable, long-term operation of the
converters.
The graphs in Figures 10-14 show the maximum
output current of the HLS Series converters at
different ambient temperatures under both natural
and forced (longitudinal airflow direction, from pin 1
to pin 4) convection. This is further illustrated in Fig.
9 as arrow ‘A’. As an example, from Figure 10, the
HLS30ZG operating at 55°C can deliver up to 22A
reliably with 100LFM forced air, while up to 25A
reliably with 200LFM forced air.
The HLS Series converters have no internal fuse.
An external fuse must be provided to protect the
system from catastrophic failure, as illustrated in
Figure 6. 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 value of the fuse without
opening. The fuse must not be placed in the
grounded input line, if any.
C
In order for the output of the HLS Series converter to
be considered as SELV (Safety Extra Low Voltage)
or TNV-1, according to all IEC60950 based
standards, one of the following requirements must be
met in the system design:
A
Pin side down
•
If the voltage source feeding the module is SELV
or TNV-2, the output of the converter may be
grounded or ungrounded.
B
•
If the voltage source feeding the module is ELV,
the output of the converter may be considered
SELV only if the output is grounded per the
requirements of the standard.
Figure 9. HLS Forced Airflow Directions (A, B, C)
Airflow directions ‘A’ and ‘C’ should be considered
equivalent in terms of the cooling effectiveness each
provides. Direction ‘B’ can offer a marginal (< 3.5%)
power capability improvement over that offered by ‘A’
or ‘C’. This characteristic is demonstrated in Fig. 15.
•
If the voltage source feeding the module is a
Hazardous Voltage Secondary Circuit, the
voltage source feeding the module must be
provided with at least Basic insulation between
the source to the converter and any hazardous
voltages. The entire system, including the HLS
converter, must pass a dielectric withstand test
Note:
Figure 15 was established with Vin=48Vdc, and figures 10-14 at
Vin=52Vdc. The resulting small difference in converter efficiency
introduces an error term that prevents accurate correlation directly
between figures 10 and 15.)
for Reinforced insulation. Design of this type of
system requires expert engineering and
understanding of the overall safety requirements
and should be performed by qualified personnel.
