QUINT-PS/24DC/24DC/ 5/CO

Data sheet

QUINT DC/DC converter – superior system availability from

SFB technology

Compact DC/DC converters from the new QUINT POWER

generation maximize your system availability. With SFB

technology (Selective Fuse Breaking Technology), 6-fold

nominal current for 12 ms, it is possible to trigger even

standard circuit breakers reliably and quickly. Faulty current

paths are switched off selectively, the fault is located, and

important system parts remain in operation. Comprehensive

diagnostics are provided through constant monitoring of the

input voltage, output voltage and output current. Preventive

function monitoring visualizes critical operating states and

indicates them to the controller before errors can occur.

The application fields for DC/DC converters are numerous

– Changing the voltage level

– Refreshing the output voltage for constant voltage at

the end of long cables

– Setup of independent supply systems by electrical

isolation

Features

– Wide-range voltage input

– Galvanic isolation

– Reverse polarity protection

– Preventive function monitoring

– Reliable starting of difficult loads with POWER BOOST

static power reserve

– Fast tripping of standard circuit breakers with dynamic

SFB technology power reserve

– High MTBF > 890000 h (40 °C)

Flexible use

– Dip coating enables use in oxidizing and sulfidizing

atmospheres with humidities of up to 100 %

– Adjustable output voltage

– Can be used in Class I, Division 2, Groups A, B, C, D

(Hazardous Location) ANSI-ISA 12.12

10 Mounting on DIN rails

10.1 Normal mounting position

Assembly:

Position the DC/DC converter with the DIN rail guide on the

top edge of the DIN rail and snap it in by pushing downward.

Removing:

Pull back the snap-on catch using a screwdriver and detach

the DC/DC converter from the bottom edge of the DIN rail.

10.2 Rotated mounting position (270° Y-axis)

A rotated mounting position can be achieved for the DC/DC

converter by mounting the device on the DIN rail at a 270°

angle. Mount the DIN rail adapter (UTA 107/30) as shown in

the figure. No additional mounting material is required.

Mounting screws: Torx® T10 (0.8 Nm ... 0.9 Nm tightening

torque).

Figure 5 Rotated mounting position (270° Y-axis)

11 Input

Connection to the input voltage is established via the screw

connectors on the DC input screw connection.

The DC/DC converter converts a DC voltage of 18...32V

into adjustable, regulated, and electrically isolated output

voltage.

The DC/DC converter requires an input voltage of 18V.

During operation, this can drop down to 14V, then observe

the voltage-dependent derating.

Figure 6 Input

11.1 Protection of the primary side

Installation of the DC/DC converter must correspond to EN

60950 regulations.

An internal fuse is provided for device protection. Additional

device protection is not required.

The connecting cables on the primary side should have

large cross sections to keep the voltage drops in the cables

as low as possible.

Other mounting positions are also possible.

Always observe position-dependent derating.

NOTE: Device may be damaged

If an internal fuse trips, this is due to a device

fault. In this case, the DC/DC converter must

be inspected in the factory.

12 Output

Connection of the output voltage is established via the

screw connectors on the DC output screw connection.

The output voltage can be set on the potentiometer.

Figure 7 Output

12.1 Protection of the secondary side

The DC/DC converter is electronically short-circuit-proof

and idling-proof. In the event of an error, the output voltage

is limited. It must be ensured that all output cables are

dimensioned accordingly for the maximum output current or

have separate protection.

The connecting cables on the secondary side should have

large cross sections to keep the voltage drops in the cables

as low as possible.

13 Output characteristic curve

The DC/DC converter works with the POWER BOOST

power reserve as shown in the U/I characteristic curve in the

figure. At ambient temperatures < 40°C, IBOOST is

permanently available. It is also available at higher

temperatures for a few minutes.

In the event of a secondary-side short circuit or overload, the

output current is limited to IBOOST. In this case, the DC/DC

converter does not switch off but supplies output current

continuously. The secondary voltage is then reduced until

the short circuit is eliminated. The U/I characteristic curve

with the POWER BOOST power reserve ensures that high

inrush currents of capacitive loads in the primary circuit can

be supplied reliably.

14 SFB technology

SFB (Selective Fuse Breaking) technology reliably switches

off faulty current paths in the event of a short circuit. In this

case, it supplies up to six times the nominal current for 12

ms. SFB technology therefore reliably triggers standard

circuit breakers. Faults are located reliably and important

system parts remain in operation.

14.1 Circuit breaker tripping characteristics

Typically, a circuit breaker trips within 3 ... 5 ms. Fast

enough to avoid voltage drops of parallel connected loads.

Figure 9 Quick tripping of circuit breakers with SFB

technology

14.2 Installation notes

To use the SFB technology of the QUINT DC/DC converter,

you must observe the following requirements:

– When designing the secondary side, consider the

configuration matrix that describes the maximum cable

lengths depending on the performance class of the DC/

DC converters, the conductor cross section, and the

circuit breaker.

– Make sure that the source to be supplied is able to

deliver a corresponding current pulse to supply the DC/

DC converter. Forexample, this can be achieved by

upstream connection of a QUINT SFB power supply

(see accessories) or suitable battery capacity.

– Ensure the lowest possible cable impedance at the

input of the DC/DC converter by using short cable

lengths and large cable cross sections.

14.3 Deactivating SFB technology

The DC/DC converter is equipped with an additional SFB

switch which can be used to deactivate SFB technology.

The SFB switch is located on the top side of the housing and

is accessible for suitable tools, such as a small screwdriver

through the vents.

The current configuration matrix can be found

The following parameters are the basis for calculation:

– Circuit breaker from Siemens, B and C characteristics

(e.g., B6: 5SY6106-6)

– B characteristic: electromagnetic tripping of the circuit

breaker at the latest at (5-fold rated current) x

(correction factor 1.2 at 0Hz) = 6-fold rated current

– C characteristic: electromagnetic tripping of the circuit

breaker at the latest at (10-fold rated current) x

(correction factor 1.2 at 0Hz) = 12-fold rated current

– Ambient temperature: +20°C

– The internal resistances of the circuit breakers are

considered.

– In addition to short circuit current, the relevant power

supply unit supplies half of the nominal current for paths

connected in parallel.
