QBC DC-DC Series Data Sheet

132-Watt Quarter-Brick Bus Converter

Safety Considerations

Output Voltage Trim

The QBC11ZH-T converter features 1500 VDC

isolation from input to output. The input-to-output

resistance is greater than 10 MΩ. This converter is

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.

The trim feature allows the user to adjust the output

voltage from the nominal. This can be used to

accommodate a different requirement or to do

production margin testing.

Industry Standard Trim (suffix –T)

The -T option units trim up with a resistor from the

Trim (#6) pin to the +Sense (#7) pin and trim down

with a resistor from the Trim (#6) pin to the –Sense

(#5) pin as shown in Figure 4.

The QBC11ZH-T converter has no internal fuse.

The external fuse must be provided to protect the

system from catastrophic failure as shown in

Figure 3. The fuse with a rating not greater than 6A

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, which occurs 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.

Figure 4. QBC11ZH-T Trim Schematic

In order for the output of the QBC11ZH-T 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:

The equations below determine the trim resistor

value required to achieve a ΔV change in the output

voltage.

Notes:

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

from the converter must not exceed its maximum rating. The

power 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.

voltages.

The entire system, including the

QBC11ZH-T converter, must pass a dielectric

withstand test for Reinforced insulation. Design

of this type of systems requires expert

engineering and understanding of the overall

safety requirements and should be performed by

qualified personnel.

3. The output voltage increase can be accomplished by either

the trim or by the remote sense or by a combination of both.

In any case the absolute maximum output voltage increase

shall not exceed 10% of the nominal output voltage
