Description
The HHS40 is a series of high efficiency, high-density, single output dc-dc converters for onboard conversion of
standard telecom and datacom input voltages into isolated low voltage outputs in a through-hole mounting
package. The two-board construction provides a cool environment for control components and the integrated
metal substrate PCB provides superior thermal management for power components resulting in enhanced product
reliability. A heat sink can be conveniently and effectively attached to the IMS base plate for operations in
elevated ambient conditions or where airflow is minimal.

The user should avoid connecting a resistor
between the ON/OFF pin and the +Vin (# 4) pin.
Typical Application
Figure 5 shows the recommended connections for the
HHS40 Series converter.
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 actually 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.

Remote Sense
Figure 5. Typical Application of the HHS40 Series
The HHS40 Series converters have the capability
to remotely sense both lines of the output. This
feature moves the effective output voltage
regulation point from the output of the unit to the
point of connection of the remote sense pins.
This feature automatically adjusts the real output
voltage of the converter in order to compensate
for voltage drops in distribution and maintain a
regulated voltage at the point of load. This is
shown in Figures 6 & 7.
These converter modules 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 68 μF electrolytic capacitor with the
ESR<0.7Ω is recommended for the HHS40 Series.
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.
If the remote sense feature is not to be used, the
sense pins should be connected locally. The
+Sense (#8) pin should be connected to the
+Vout (#9) pin directly at the output of the
converter and the –Sense (#6) pin should be
connected to the -Vout (#5) pin directly at the
output of the converter.
For output decoupling we recommend to use a 10 μF
tantalum and a 0.1 μF ceramic capacitors connected
directly across the output pins of the converter. Note,
that the capacitors do not substitute the filtering
required by the load.
If sense pins are not connected to load, or the
respective output pins, the converter will not be
damaged, but may not meet the output voltage
regulation specifications.
Shutdown Feature Description
The ON/OFF (# 3) pin of the HHS40 Series converters
are referenced to the –Vin (# 1) pin (see Figure 5).
Both negative and positive logic models are available.
With negative logic (which is denoted by the suffix “–N”
in the part number), when the ON/OFF pin is pulled low,
the unit is turned on.
With the 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.
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.

OUTPUT VOLTAGE TRIM
Negative-Trim Models (No P/N suffix)
All HHS40 negative-trim models trim up with a
resistor connected from the TRIM (#7) pin to the
(-) Sense (#6) pin and trim down with a resistor
from the TRIM pin to the (+) Sense (#8) pin as
shown in Figure 7.
Industry Standard (Positive) Trim (-T suffix)
The trim feature allows the user to adjust the output
voltage from its nominal value.
The HHS40 positive-trim (-T) models trim up with a
resistor from the Trim (#7) pin to the +Sense (#8) pin
and trims down with a resistor from the Trim pin to the –
Sense (#6) pin as shown in the Figure 6.

1. When the output voltage is trimmed up, the output power from

determined by measuring the output voltage on the output pins,
and multiplying it by the output current.

including the HHS40 converter, must pass a
dielectric withstand test for Reinforced
insulation. Design of this type of systems
requires expert engineering and under-
standing of the overall safety requirements
and should be performed by qualified
personnel.
4. Either Rup or Rdown should be used to adjust the output voltage
according to the equations above. If both Rup and Rdown are
used simultaneously, they will form a resistive divider and the

Thermal Considerations
Safety Considerations
The HHS40 Series converters are designed for
The HHS40 Series converters feature 1500 Volt DC
isolation from input to output. The input-to-output
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 or additional requirements
may be needed for specific applications.
natural or forced convection cooling.
The
maximum allowable output current of the
converters is determined by meeting the derating
criteria for all components used in the converters.
For example, the maximum semiconductor
junction temperature is not allowed to exceed
120 °C to ensure reliable long-term operation of
the converters.
The graphs in Figures 8 & 9 show the maximum
output current of the HHS40 Series converters at
different ambient temperatures under both natural
and forced convection. (longitudinal airflow
direction, from pin 1 to pin 4).
The HHS40 Series converters have no internal fuse.
An external fuse must be provided to protect the system
from catastrophic failure, as illustrated in figure 5. Refer
to the “Input Fuse Selection for DC/DC converters”
application note on www.power-one.com for proper
selection of the input fuse. 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.
For example, from Figure 8, the HHS40ZE
operating at 55 °C can deliver up to 27 A reliably
with 200 LFM forced air, while up to 36 A reliably
with 400 LFM forced air.
In order for the output of the HHS40 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:
•
If the voltage source feeding the module is SELV or
TNV-2, the output of the converter may be
grounded or ungrounded.
•
If the voltage source feeding the module is ELV, the
output of the converter may be considered SELV
