- 5 A charging current ensures fast availability
- Battery start-up without mains power
- Parameter setting via interface and rotary switch
Capacitive UPS:- Easy to expand by adding capacitive modules

EasyB - The modular 24 V circuit breaker system
- The modular 24 V circuit breaker system of the EasyB
series offers its users an explicit added value by numerous equipment
versions and extensive accessories in addition to the tailored circuit
protection. The circuit breaker modules, optionally with communication
interface, can be operated individually or create one electrical and
mechnical unit by attaching them to each other. With a width of only 12 mm,
flexibility and space savings are two big advantages of EasyB. The system
doubles space saving with the new 2-channel circuit breaker. It combines two
independent protection channels within the same enclosure. Installation and
wiring are significantly easier since the signal terminals are connected
automatically by attaching them. For power circuits in which more than two
loads are to be supplied, output distribution modules with eight additional
outputs are available. Besides the Modbus RTU, the new IO-Link module is
available for communication purposes.
Isolating Transformers TT3 Neo
- For reliable protection, the ideal solution is to use
isolating transformers with electrical isolation between the windings. TT3
Neo, the next generation of BLOCK TT3 transformers, guarantees safe
isolation in high power ranges from 10 kVA to 1 MVA.
Integrated safety
- Application benefits
In order to protect Transformers against overcurrent according to standards,
specific protective measures are to be initiated by the user. Such measures
are now no longer required, thanks to the BLOCK FAIL-SAFE transformer. The
following examples illustrate the unique range of advantages of the
FAIL-SAFE transformer.
The basic power supply
- The economic Power supplies in the Power Compact series
set new standards in their class. Above-average robustness against transient
overvoltages and equipped with essential additional aspects for a worldwide
high plant availability.
- Resistant to transient overvoltages up to 4 kV
- Fast tripping of standard bi-metal circuit breakers
- DC OK signal contact
- Push-in terminals
- Parallel operation
- Robust DIN rail mounting
Electronic circuit breakers
- Electronic circuit breakers are used for selective
protection of DC circuits. They protect circuits against overcurrents and
short circuits with a much higher degree of precision compared to classic
circuit breakers.
- Reliable switch-on of high capacities (> 50.000 μF)
- Group alarm signal for simple diagnosis
- Optimum tripping characteristic for any application
- Sequential and load-dependent switching-on of channels
- Adjustable tripping current per channel
- Comprehensive single-channel diagnosis
- Remote switch-on/off of any channels
- Remote reset of tripped channels

LED Driver – reliable and durable
- Extremely durable
The economic LED drivers of the PLED series set standards in their class.
They provide outstanding performance against transient overvoltages and
therefore are extremely reliable and durable. LED drivers are the first
choice no matter if simple switching or dimming is necessary.
High service life
Very high efficiency, a highly sophisticated topology and the right
component dimensioning lead to a very high service life of more than 50.000
h at maximum ambient temperature up to 60 °C.
Dimming
In addition to an output current selector switch with two positions the LED
drivers provide dimming via an optional 1-10 V interface. With this
interface the output current can optionally be set passively by an external
resistor or actively with a separate control unit. The range for setting the
output current varies from 10-100 %.
The 1-10 V interface provides a reinforced insulation against line input as
well as LED output, thus providing total flexibility when installing dimming
controllers in the driver.
LED protection against overtemperature
To protect the LEDs against overtemperature an external NTC can be connected
to the driver. When exceeding the maximum temperature the driver reduces the
output current to 50 % of the adjusted LED currents, thus safely preventing
the LED from overheating.

100% interference-free washing
- With its industrial washing machines, offering capacities
from 5 kg to 73 kg, Belgian company IPSO has made a name for itself
worldwide. And it was the mobile BLOCKLAB that made this possible, since
BLOCK Belgium performed comprehensive EMC tests directly on site during the
development phase. This rapid production-based application resulted in an
excellent price/performance ratio for the customer. However, BLOCK engineers
did not have a great deal of space to work with, as the filter-transformer
combination had to be fitted in the last available space within the machine.
The complete solution, developed and produced by BLOCK, keeps the machines
permanently free of interference: Shielding as per class B (EN 55011) at 17
to 37 A, controlled by a transformer at 63 to 500 VA, insulated with
BLOCKIMPEX.
High-frequency access
- An aircraft ground power supply provides aircraft with
power after landing and before taking off. This involves a considerable
amount of power, based on 400 Hz. To ensure high reliability, even over a
long service life, BLOCK developed a high performance transformer
specifically tailored to these requirements for mobile use. The BLOCKIMPEX
sealing system keeps everything running safely, whatever the weather.
Interference-free error messages
- For fire alarm control centres manufactured by detectomat,
BLOCK supplies a "complete unit", consisting of a toroidal transformer and
an interference filter mounted within a single housing. The components are
prewired and connected to a terminal. The unit has been matched precisely to
the size of the fire alarm control centre.

Future Winding for next power generation
- Launching into a new technology
BLOCK's new in-house developed winding technology 4D PowerCoil is taking
performance optimization of inductive winding products into a new dimension.
The extraordinary variability in the design of the winding structure comes
with a number of benefits for winding products: Optimal cooling by
maximizing the heat-emitting conductor surface while also creating cooling
ducts via the winding structure and minimal proximity losses with rising
switching frequencies are just some of the strengths of this
state-of-the-art technology.
- COOL
excellent heat dissipation achieved by our all new winding technology - LOW LOSSES
reduced proximity effect losses due to optimized winding design - FREE STYLE
BLOCK winding technology 4D PowerCoil allows free geometrical shaping - LONG LIFE
maximum reliability by using minimum insulation material - POTENTIAL CONTROL
controllable electrical field for low partial discharge - FORCED COOLING

SFA 500
- All-pole sine filters solve EMI problems on frequency
inverters
Due to the increase in system networking and in light of Industry 4.0,
high-frequency interference pulses pose a constant risk for communication
across the entire production process.
Not only does the new SFA 500 all-pole sine filter series from BLOCK solve a
multitude of such EMI problems, it also increases the efficiency of drive
systems controlled by frequency inverters.
SFA 500 Highlights - Compact Design
- Use of extremly long motor cable lenghts possible
- Significant reduction of leakage currents
- Elimination of bearing currents
- Efficiency optimisaton of the drive system
Liquid cooling
- During operation, inductive components generate losses
which must be discharged into the surroundings in the form of heat. By
employing fluid cooling, significantly greater heat dissipation can be
achieved, which allows an increased performance and reductions in size.
With the present test station, the most diverse challenges from cooling
circuits can be understood. Our products can therefore be adapted optimally
to respective applications.
