Block's PowerVision power control modules were developed for applications where an IEC61131-2 compliant output voltage is satisfactory.
Block has released the PowerVision range of integrated power control modules.
For many applications, a primary switch mode power supply with stabilised output voltage is unnecessary.
Normally, a regulated outpout voltage that complies with the tolerances specified in the international standard IEC61131-2 is perfectly adequate.
The PowerVision was developed to meet these requirements.
The system is not only better value than conventional primary switch mode power supplies, but is also significantly smaller and lighter.
The system is ideal for PLC-based control applications and comprises a power supply unit with programmable control module for set up of parameters.
With its slim, compact design, the Block PV 400 with integrated control module enables users to recall, control and set up performance limits/controls via a PC connection or the internet.
In case of over-current, the PV range has a Real Power Boost function that provides 200% load in reserve for up to four seconds, after which the safety programme steps in.
This makes it possible, using selective fusing, to supply multiple circuits so that in the event of a single circuit fault, the installation as a whole is not brought to a standstill.
Other features include an LCD and three coloured LEDs positioned on the side of the unit.
These LEDs alert the user to safe operation (green), warnings (yellow) and faults (red).
With the latest efficient switch mode technology, the PowerVision is also up to 50% smaller than standard power supplies, making it ideal for companies that need to save space in control panels.
Another design feature on the Power Vision is its single-handed mounting system.
A single screw opens or locks the the mounting latch, ensuring safe installation or removal.
The user requires only one hand to mount the unit onto a standard DIN rail.
A screwless design ensures a snug fit with the mounting wall.
If required, this mounting system can also be fixed on the right side of the unit to enable a flat mounting on the DIN rail.
Conventional screw mounting is also provided via mounting holes.
One of the PV range goes even further with integrated line monitoring functionality.
An integrated monitor enables the user to view incoming supply voltages.
