QM48T/S14120 DC-DC Converter Data Sheet

36-75 VDC Input; 12 VDC @ 14 A Output

Protection Features

Input Undervoltage Lockout

Safety Requirements

Input undervoltage lockout is standard with this

converter. The converter will shut down when the

input voltage drops below a pre-determined voltage.

The converters meet North American and

International safety regulatory requirements per

UL60950-1,

CSA60590-1,

EN60950-1,

and

The input voltage must be typically 34 V for the

converter to turn on. Once the converter has been

turned on, it will shut off when the input voltage

drops typically below 32 V. This feature is beneficial

in preventing deep discharging of batteries used in

telecom applications.

IEC60950-1. Basic Insulation is provided between

input and output.

To comply with safety agencies’ requirements, an

input line fuse must be used external to the

converter. A 12 A fuse is recommended for use with

this product.

All QM converters are UL approved for a maximum

fuse rating of 15 Amps. To protect a group of

converters with a single fuse, the rating can be

increased from the recommended value above.

Output Overcurrent Protection (OCP)

The converter is protected against overcurrent or

short circuit conditions. Upon sensing an overcurrent

condition, the converter will switch to constant

current operation and thereby begin to reduce output

voltage. When the output voltage drops below 60%

of the nominal value of output voltage, the converter

will shut down.

Electromagnetic Compatibility (EMC)

EMC requirements must be met at the end-product

system level, as no specific standards dedicated to

EMC characteristics of board mounted component

dc-dc converters exist. However, Power-One tests its

converters to several system level standards,

primary of which is the more stringent EN55022,

Once the converter has shut down, it will attempt to

restart nominally every 100 ms with a typical 3% duty

cycle. The attempted restart will continue indefinitely

until the overload or short-circuit conditions are

removed or the output voltage rises above 60% of its

nominal value.

Information

equipment

Radio

disturbance characteristics-Limits and methods of

measurement.

Once the output current is brought back into its

specified range, the converter automatically exits the

hiccup mode and continues normal operation.

An effective internal LC differential filter significantly

reduces input reflected ripple current, and improves

EMC.

Output Overvoltage Protection (OVP)

With the addition of a simple external filter, all

versions of the QM-Series of converters pass the

requirements of Class B conducted emissions per

EN55022 and FCC requirements. Please contact

Power-One Applications Engineering for details of

this testing.

The converter will shut down if the output voltage

across Vout(+) (Pin 8) and Vout(-) (Pin 4) exceeds

the threshold of the OVP circuitry. The OVP circuitry

contains its own reference, independent of the output

voltage regulation loop. Once the converter has shut

down, it will attempt to restart every 100 ms until the

OVP condition is removed.

Overtemperature Protection (OTP)

The converter will shut down under an

overtemperature condition to protect itself from

overheating caused by operation outside the thermal

derating curves, or operation in abnormal conditions

such as system fan failure. After the converter has

cooled to a safe operating temperature, it will

automatically restart.
