Power supplies for 24 V and 48 V DC
Beckhoff's comprehensive portfolio offers 1- and 3-phase DIN rail power supplies with output currents from 2.5 A to 40 A. Every series wins over customers with consistently high efficiency and low heat loss throughout the range. This has a positive effect on the lifetime and reliability of the power supply units and on machine and system availability.
Power supplies with an integrated EtherCAT interface also enable monitoring of the DC output and AC input ranges and thus allow the network and system to be monitored – the operating status of the system can be optimally analyzed, and errors can be detected at an early stage. TwinCAT supports application-oriented parameterization, reading, and resetting of the device-internal values here.
In terms of output, the DIN rail power supplies operate in line with the UI characteristic curve and can provide up to 1.44 kW of power. Depending on the variant type, the constant current or hiccup mode, extra power, and reliable tripping of circuit breakers are included in the power supply unit's functionality. This enables heavy loads to be started and protects the machines and plant parts in the event of a failure. A wide-range input allows these products to be used worldwide. In addition, industries with special requirements such as the semiconductor industry (SEMI F47), shipbuilding (DNV GL), and hazardous areas (Class I Division 2, IECEx, and ATEX) can also be served.
Advantages at a glance
High efficiency
The efficiency describes the ratio of input power to output power of a power supply. The difference between input and output power is lost as heat. High efficiencies mean a low heat loss, a long lifetime and high reliability.
The Beckhoff power supplies impress with high efficiencies of up to 96.3%. The low heat loss preserves all the components in the control cabinet and reduces energy costs. The higher the efficiency, the smaller the devices can be made. On this basis, Beckhoff offers a portfolio of power supplies with universally space-saving and compact housings.
High reliability
When using power supplies, high long-term reliability is an important feature. The Beckhoff power supplies meet this requirement by being developed according to a special electronic principle. This relies on a special construction with good, convection-cooling properties. Components are thus exposed to lower thermal stress and achieve a long lifetime. In addition, components that are exposed to less stress are able to retain their technical properties, which has a positive effect on reliability and is a genuine quality feature of the Beckhoff power supplies. Every single device is tested accordingly to rule out early failures (100% inspection).
Wide-range input
Mains voltages that are different worldwide place high demands on power supplies. So that they can be used worldwide without problems, the Beckhoff power supplies are equipped with so-called wide-range inputs. For example, most single-phase power supplies have a large input voltage range of 100…240 V AC for 50…60 Hz.
Extra power
The extra power feature describes the permitted overloading of the power supply.
It is divided into two categories:
- permanent output power, up to 120%
- output power for 4 seconds, up to 150%
This is advantageous for loads with a changing power requirement. Dynamic load peaks on the consumers are served and intercepted by the extra power. In addition, motors with high starting currents or consumers with large input capacities can be started.
Precise fuse tripping
The load circuits in the 24 V DC environment are often individually protected with circuit breakers or fuses. If there is a short-circuit in a power circuit, the fuse or circuit breaker needs a certain amount of overcurrent to open in time. These currents are called peak currents. They are available for a few milliseconds and are many times higher than the rated current.
The Beckhoff power supplies from the PS2000 and PS3000 series are able to allow a precise tripping of the fuse with the peak current. In addition, the peak current helps when starting large power-consuming loads such as magnetic coils, pneumatic modules or contactors.
Back EMF
In the course of the application, special loads such as braking motors or inductors can feed a voltage back to the power supply. The Beckhoff power supplies are resistant to these so-called power feedbacks and react without malfunctions. Due to appropriately well-dimensioned output capacitors, the power supply units are particularly suitable for motion applications.
