Typical Application

Figure 6 shows the recommended connections for

the HLS Series converter.

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

capacitor with the ESR<0.7Ω is recommended for

the HLS 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.

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.

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.

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.

Negative-Trim (No P/N suffix)

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.

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 HLS 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 HLS Series converters feature 1500 Volt DC

isolation from input to output. The input to output DC

resistance is greater than 10M. 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 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.

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:

• 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 only if the output is grounded per the

requirements of the standard.

• 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

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.

Thermal Considerations

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.

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.

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.)
